* Version 6.32
 :PROPERTIES:
 :VISIBILITY: content
 :CUSTOM_ID: v6.32
 :END:

** Rewrite of org-mobile.org, for MobileOrg 1.0 (build 20)

MobileOrg is currently under review at the iPhone App Store.  You
will need Org-mode version 6.32 to interact with it.

** Added support for habit consistency tracking
    
/org-habit.el/ contains new code to track habits.  Please
configure the variable org-modules to activate it.  When active,
habits (a special TODO entry) will be displayed in the agenda
together with a "consistency graph".  Habit tracking is described
in a new [[http://orgmode.org/manual/Tracking-your-habits.html][manual section]].

Thanks to John Wiegley for this contribution.
    
** New context-aware tag auto-exclusion 

After writing a function relating to location and context
information, you will be able to press =/ RET= in the agenda to
exclude tasks that cannot be done in the current context. 
For details, see the information about filtering in the manual.

Thanks to John Wiegley for a patch to this effect.

** New clock resolving tools

When clocking into a new task while no clock is running, Org now
checks for orphaned CLOCK lines and offers to repair these before
starting the clock.  You can also configure this feature to check
for idle time and prompt you to subtract that time from the
running timer.
    
See the new [[http://orgmode.org/manual/Resolving-idle-time.html][manual section]] for more details.
    
Thanks to John Wiegley for a patch to this effect.

** Mutually exclusive tag groups can now have a name in the tags interface

The customize interface allows to optionally add a string to the
beginning or end of such a group.
    
Thanks to James TD Smith for a patch to this effect.

** Agenda Search view: Search for substrings
    
The default in search view (/C-c a s/)is now that the search
expression is searched for as a /substring/, i.e. the different
words must occur in direct sequence, and it may be only part of
a word.  If you want to look for a number of separate keywords
with Boolean logic, all words must be preceded by =+= or =-=.

This was, more-or-less, requested by John Wiegley.

** Make space and backspace scroll the show window in the agenda

Pressing SPC again after using it to show an agenda item in
another window will make the entire subtree visible, and show
scroll it.  Backspace and DEL will scroll back.

This was a request by Eric Fraga.
    
** File tags are now offered for completion during a tag prompts

Requested by Matt Lundin.

** Make `- SPC' an agenda filter that selects entries without any tags
    
Request by John Wiegley.

** Better way to edit multi-line macro definitions

The editing tool key =C-c '= now also edits =#+MACRO=
definitions, including multiline macros.

** Restructured Manual

The manual has been slightly reorganized.  The archiving stuff,
which was - somewhat obscurely - hidden in the /Document
Structure/ chapter, has been moved into the new chapter
/Capture-Refile-Archive/.  Also, there is a new chapter /Markup/
which contains both the markup rules (moved there from the Export
chapter) and the documentation for embedded LaTeX.

** Improved figure placement in LaTeX and HTML export
    
Text can now be wrapped around figures.  See the manual for
details.

** Allow date to be shifted into the future if time given is earlier than now
    
By setting

:     (setq org-read-date-prefer-future 'time)

you indicate to Org that, if you only give a time at the
date/time prompt, and if this time is earlier then the current
time, then the date of tomorrow will be assumed to be valid for
this event.  A similar mechanism was already in place for dates,
but now you can make it work for times as well.

** Collected changes in org-babel
- Source blocks can now reference source-blocks in other files
  using =filepath:srcname= syntax.
- Inline code blocks like =src_python{2+2}= are now exported
- Remote source block calls using the =#+lob: srcname(arg=val)=
  syntax can now be exported.
- When =:file= is supplied with an =R= block, graphics are
  automatically sent to file and linked from the org buffer, thus
  appearing on export.  The image format is obtained from the
  filename extension.  Possible values are =.png, .jpg, .jpeg,
  .tiff, .bmp, .pdf, .ps, .postscript=, defaulting to =png=.
- Results can be returned as parseable code using =:results code=,
  and as pretty-printed code using =:results pp= (emacs-lisp,
  python, ruby).  Thanks to Benny Andresen for the idea and patch
  for emacs-lisp.
- When =:file filename= is supplied, =:exports file= is unnecessary
- Header args are taken from org-file-properties in addition to
  properties active in the subtree.
- =:noweb= header argument now expands noweb references before
  source-block evaluation.
- Tangling honours the new org variable
  org-src-preserve-indentation, so that correct code is output for
  a language like python that depends on indentation.

** Changes in org-exp-blocks.el
- Interblocks export has been simplified.
- Support for R code (=begin_R= blocks and inline =\R{}=) has been
  removed.  Please use org-babel instead.

* Version 6.31
 :PROPERTIES:
 :CUSTOM_ID: v6.31
 :END:

** Org-babel is now part of the Org distribution

Org-babel provides the ability to execute source code in many
different languages within org-mode documents.  The results of
code execution -- text, tables and graphics -- can be integrated
into Org-mode documents and can be automatically updated during
publishing.  Since Org-babel allows execution of arbitrary code,
the range of tasks that can be addressed from within an Org mode
file becomes very large.  Examples of ways in which Org-babel
might be used include

- Documenting a task that involves some programming so that it is
  automatically repeatable
- Creating dynamic (executable) reports that respond to changes
  in the underlying data (Reproducible Research)
- Exportation of code contained in an Org-mode document into
  regular source code files (Literate Programming)

Additionally, Org-babel provides a programming environment within
Org files, in which data can be transmitted between parameterised
source code blocks in different languages, as well as between
source code blocks and Org-mode tables.

A simple API is defined so that users can add support for new
"languages" (broadly construed).  Languages currently supported
are:

- asymptote
- css
- ditaa
- dot
- emacs-lisp
- gnuplot
- haskell
- ocaml
- python
- R
- ruby
- sass
- sh
- sql

Org-babel was designed and implemented Eric Schulte with continued
significant help on both accounts from Dan Davison.

** MobileOrg support

Richard Morelands iPhone/iPod Touch program [[http://mobileorg.ncogni.to/][MobileOrg]] can view
Org files, mark entries as DONE, flag entries for later
attention, and capture new entries on the road.  Org-mode has now
support to produce a staging area where MobileOrg can download
its files, and to integrate changes done on the phone in a half
automatic, half interactive way.  See the new appendix B in the
manual for more information.


** Indented lines starting with "#+ " are treated as comments

To allow comments in plain lists without breaking the list
structure, you can now have indented comment lines that start
with "#+ ".

** New STARTUP keyword `showeverything'
    
This will make even drawer contents visible upon startup.
Requested by Jeff Kowalczyk.

** New contributed package org-invoice.el

This package collects clocking information for billing
customers.

Thanks to Peter Jones for this contribution.

** Encrypting subtrees

/org-crypt.el/ by John Wiegley and Peter Jones allows encryption
of individual subtrees in Org-mode outlines.  Thanks to John and
Peter for this contribution.

** Agenda: Support for including a link in the category string
    
The category (as specified by an #+CATEGORY line or CATEGORY
property can contain a bracket link.  While this sort-of worked
in the past, it now is officially supported and should cause no
problems in agenda display or update.  The link can be followed
by clicking on it, or with =C-c C-o 0=.

This was a request by Peter Westlake.

** Inconsistent changes

*** Agenda now uses =f= and =b= to move through time

Up to now, the Org-mode agenda used the cursor keys =left= and
=right= to switch the agenda view forward an backward through
time.  However, many people found this confusing, and others
wanted to be able to do cursor motion in the agenda, for example
to select text.  Therefore, after an extensive discussion on
=emacs-orgmode@gnu.org=, it was decided to use the =b= and 
=f= keys instead, and to let the cursor keys do cursor motion
again.

*** Agenda follow mode is now on the =F= key

This was necessary to free up the =f= key, see above.

** Details

*** Maintenance

**** New command to submit a bug report

There is now a special command =M-x org-submit-bug-report=.  This
command will create a mail buffer with lots of useful details.
In particular, it contains complete version information for Emacs
and Org-mode.  It will also (if you agree to it) contain all
non-standard settings of org-mode and outline-mode related
variables.  Even if you do not sent your emails from within
Emacs, please still use this command to generate the information
and then copy it into your mail program.

The command will not generate and include a =*Backtrace*= buffer,
please do this yourself if you have hit an error.  For more
information, see the [[http://orgmode.org/manual/Feedback.html#Feedback][feedback section]] of the manual.

**** New contributed package org-track.el

This package allows to keep up-to-date with current Org
development, using only Emacs on-board means.  So if you don't
want or cannot use =git=, but still want to run the latest and
hottest Org-mode, this is for you.

Thanks to Sebastian Rose for this contribution.

*** Agenda

**** Agenda now uses =f= and =b= to move through time

Up to now, the Org-mode agenda used the cursor keys =left= and
=right= to switch the agenda view forward an backward through
time.  However, many people found this confusing, and others
wanted to be able to do cursor motion in the agenda, for example
to select text.  Therefore, after an extensive discussion on
=emacs-orgmode@gnu.org=, it was decided to use the =b= and 
=f= keys instead, and to let the cursor keys do cursor motion
again.

**** Agenda follow mode is now on the =F= key

This was necessary to free up the =f= key, see above.

**** The agenda can be put into a dedicated frame

When the variable =org-agenda-window-setup= has the value
=other-frame=, then the new frame created to show the agenda
will now have the window marked as /dedicated/.  As a
consequence, exiting the agenda while the agenda is the only
window on the frame will kill that frame.

This was a request by Henry Atting.

**** New mode to show some entry body text in the agenda

There is now a new agenda sub-mode called
=org-agenda-entry-text-mode=.  It is toggled with the =E= key.
When active, all entries in the agenda will be accompanied by a
few lines from the outline entry.  The amount of text can be
customized with the variable =org-agenda-entry-text-maxlines=.

This was a request by Anthony Fairchild, Manish, and others.

**** Improve following links from the agenda
    
=C-c C-o= in the agenda will now offer all links in the headline
and text of an entry.  If there is only a single link, it will be
followed immediately.

**** Avoid some duplicate entries

There is a new variable that can be used to avoid some duplicate
agenda entries: =org-agenda-skip-scheduled-if-deadline-is-shown=
If that is set, it avoids that an entry shows up in the agenda for
today for both a scheduling and a deadline entry.  See the
docstring of the variables for more details.

This partially addresses a request by Samuel Wales. 

**** Mark the running clock in the agenda.

If the entry currently being clocked is present in the agenda, it
will be highlighted with the face =org-agenda-clocking=.

This was a request by Rainer Stengele.


*** Export

**** Allow LaTeX export to use the listings package

The LaTeX =listings= package can now be used for formatting
fontified source code in many programming languages.  For more
information, see
http://thread.gmane.org/gmane.emacs.orgmode/16269 and
http://orgmode.org/worg/org-faq.php#fontified_source_code_w_latex

Thanks to Eric Schulte for this patch.

**** Remove table rows that only contain width and alignment markers
    
The width and alignment in table columns can be set with a cookie
like "<10>" or "<r>" or "<r10>".  In order to keep Org from
exporting such lines, the first column of a line should contain
only "/".  However, for convenience, there is now a special case:
If the entire row contains only such markers, the line will
automatically be discarded during export, even is the first
column is not "/".

**** Allow Macro calls to span several lines.

Macro calls may now span several lines, to write several
arguments in a cleaner way.  The result of a macro call can also
span several lines, by inserting the string "\n" (backslash
followed by n) into the value in the macro definition.

These were requests by Stefan Vollmar.

*** Misc

**** Quick access to all links in an entry

If =C-c C-o= is called while the cursor is in a headline, but not
directly on a link, then all links in the entry will be offered
in a small menu.  If there is only a single link, it will be
followed without a prompt.

**** Visibility Cycling: Allow to show all empty lines after a headline
    
=org-cycle-separator-lines= can now be set to a negative value,
to indicate that, if the number of empty lines before a visible
entry is greater than the specified number, then *all* empty
lines should be shown.

This was a request by "PT" whatever this means.

**** Allow language names to replace some strange major mode names

Sometimes a language uses a major mode which can't be guessed
from it's name.  There is now a new variable =org-src-lang-modes=
which can be used to map language names to major modes when this
is the case.  This is used when editing a source-code 
block, or when exporting fontified source-code with htmlize.

Thanks to Eric Schulte for a patch to this effect.

**** iswitchb support for many completion prompts
    
This is enabled using =org-completion-use-iswitchb=, and follows
the same model of usage as for ido users.

Thanks to John Wiegley for a patch to this effect.

**** New commands to set the effort property of an entry

There is now a special command, =C-c C-x e= to set the =Effort=
property of an entry.  From the agenda you can even use =e=.
If you have set up allowed values for the =Effort= property, then
using a prefix argument will directly select the nth allowed
value.  For example, in the agenda, =5 e= will select the 5th
allowed value.

This was a request by Michael Gilbert

**** Edit src works now better with killing buffer

Thanks to Dan Davison for a patch to this effect


* Version 6.29
 :PROPERTIES:
 :CUSTOM_ID: v6.29
 :END:

** Structure editing and cycling

*** New minor mode =org-indent-mode=

This mode implements outline indentation similar to clean view,
but in a dynamic and virtual way, at display time.  I have wanted
this functionality for years and tried several implementations,
all unworkable.  Emacs 23 has finally made it possible.  So this
solution is for Emacs 23 only, and I am not sure yet how stable
it really is.  Time will tell.

Currently I do not recommend to turn it on globally using
the variable =org-startup-indented=.  But you can turn it on
for a particular buffer using

#+begin_src org
  ,#+STARTUP: indent
#+end_src

Turning on this minor mode automatically turns on
=org-hide-leading-stars=, and it turns off
=org-adapt-indentation=.

*** Skip CHILDREN state if there are no children

When a subtree does not have any children, visibility
cycling now skips the CHILDREN state.  You can customize
this behavior with the variable
=org-cycle-skip-children-state-if-no-children=.

*** Nodes without keyword can now be counted for statistics

See the variable =org-provide-todo-statistics= for details.
It can be the symbol =all-headings=, or a list of TODO
states to consider.

This was requested by David A. Gershman.

*** New function =org-list-make-subtree=

This function converts the plain list at point into a
subtree, preserving the list structure.  The key for this
command is =C-c C-*=.  Thanks to Ilya Shlyakhter for this
suggestion.

*** Headlines can be fontified to the right window border

Use the variable =org-fontify-whole-heading-line= to turn
this on.  Then headline fontification will include the final
newline.  If your setup for headline faces includes a
background different from the default background, this setup
creates a visual line across the window.

*** Inline tasks have become better citizens

The new key =C-c C-x t= inserts an inline task including an
END line.  Inline tasks play along with (i,e, are ignored
by) link creation and footnotes.  Inline tasks with an =END=
line can be refiled and archived.  During the refile/archive
operation, the tasks become normal tasks and the =END= line
disappears.

These improvements reflect reports and requests by Peter
Westlake and Matt Lundin.

*** Archive subtree and move to next visible task

When archiving a task, the cursor now ends up on the next
headline, so the repeated application of the archiving
command will archive successive tasks.

Thanks to Bernt Hansen for a patch to this effect.

*** Renumbering the fn:N-like footnotes

The new footnote action =r= will renumber simple =fn:N=
footnotes in the current document.  The action =S= will
first do the renumbering and then sort the footnotes (the
=s= action).

This was a request by Andreas Röhler.

*** Automatic sorting and renumbering

Customize the new variable =org-footnote-auto-adjust= or use
the =#+STARTUP= option =fnadjust= to get automatic
renumbering and sorting of footnotes after each
insertion/deletion.

This was a request by Andreas Röhler.

*** Improvements to plain-list-cycling with TAB.

TAB now by default cycles visibility in plain lists if the
cursor is at a plain list item.  This corresponds to the new
default value =t= of =org-cycle-include-plain-lists=.  If
you want to treat plain list items as part of the outline
hierarchy during cycling of outline headings (this is what a
=t= value used to mean), set this variable to =integrate=.

*** Force bullet type changes during plain list demotion

We now have a mechanism to force a particular bullet type
when demoting a plain list item.  See the variable
=org-list-demote-modify-bullet= for details.

This was a request by Rainer Stengele.


** Tables

*** Relative row references may now cross hlines

A relative row reference like @-1 in a table may now reach
across a horizontal separator line.  I hope this will not
break any important tables out there, but I think it is the
right thing to do.

The sole original reason for not allowing such crossing was
to implement running averages of one column in the next.
This can now be done using field formulas near the beginning
and end of the column, and a column formula for the central
part.

See the variable =org-table-relative-ref-may-cross-hline=
for more details.

*** Cut or copy single fields

=C-c C-x C-w= and =C-c C-x M-w= now act on single table
fields if there is no active region defined.

** Links

*** Find agenda files linking to the current location

The new command =org-occur-link-in-agenda-files= creates a
link like =org=store-link= would, and then searches all
agenda files for this link.  So for example, you could be in
a GNUS message, trying to find tasks that have links to this
message.

*** Include stored links into link completion

When inserting a link with =C-c C-l=, TAB completion will
now not only access link prefixes, but also the stored
links.


** Agenda

*** Bulk commands: Add Schedule and Deadline processing

Agenda bulk commands on marked entries now can also set the
scheduling date or a deadline.  Normally, all entries will
be set to the specified date.  However, when writing the
change as "++5d" or "++2w", then each time stamp will
independently be shifted by that amount.

*** Tags-todo searches: No longer force to list sublevels

For historic reasons, =org-tags-match-list-sublevels= was
forced to =t= in tags-todo agenda searches.  Now we no
longer do this and accept the user setting of this variable.

Thanks to Patrick Bahr for bringing this up.


** Export

*** Use file-source.org format instead of file.org-source

When publishing the source Org file to the source directory
(i.e. if the publishing directory is the same as the source
directory), then the file name will now look like
=file-source.org= and =file-source.org.html=.  Note that if you
do use this kind of setup, you probably want to specify

#+begin_src emacs-lisp
:exclude "-source\.org"
#+end_src

in your publishing project, to avoid that a new generation of
=-source= files is created each time you publish the project.

*** LaTeX export: Skip title command when there is no title

Using =#+TITLE:= without a value makes the LaTeX export
ignore the value of =org-export-latex-title-command=.

*** New option =org-export-html-footnote-format=

This defines the format for footnote references.  This
string must contain =%s= which will be replaced by the
footnote label.

*** More export options for source code examples

Allow whitespace in code references.  Allow the =-r= switch
to remove the references in the source code even when the
lines are not numbered: the labels can be explicit enough.
Note that =-r -k= is the same as no switch at all.

Thanks to Ulf Stegemann for bring this up.

*** LaTeX export: Allow more environment for low-level headings

The user can now define a non-standard environment or macro
to handle export of low-level headings to LaTeX.

For details, see the variable =org-export-latex-low-levels=.

*** LaTeX export: Add postscript file extensions for images

Some people process LaTeX files not directly to pdf, but go
through dvi and then to ps or pdf.  In that case, allowed
images are ps and eps files, not pdf and jpg.

This commit adds the two extensions, so that export using
that alternative path can be supported better.  However, it
is up to the user to make sure that the images are actually
compatible with the backend.

*** HTML export: Show UP and HOME links

=org-export-html-link-up= and =org-export-html-link-home=
are now also inserted into normal HTML export, above the
page title.

*** General mechanism for local variable settings

Many different people want to set many different variables
in a buffer-local way for export.  This cannot be done with
file variables, because the Org buffer is not current while
the exporter is running.

Lots of variables can be set with the =#+OPTIONS= lines, but
finding abbreviations goes only so far.

Therefore we have now a general mechanism that can be used
to bind variables during export operations.

A line like:

#+begin_src org
  ,#+BIND: variable value
#+end_src

will bind the variable to value.  For example, the line

#+begin_src org
  ,#+OPTIONS: toc:nil
#+end_src

can now equivalently be written as

#+begin_src org
  ,#+BIND: org-export-with-toc nil
#+end_src

*** Clean out publishing timestamp directory

When changing the publishing setup, old timestamp files can
be left behind.  Forcing publishing of all projects with
=C-u C-c C-e E= will remove all existing timestamp files.

** Miscellaneous

*** Calendar for reading a date forced into current frame.

Separate-frame setup for calendar had caused problems in
AquaEmacs.

*** Set timers for headlines

You can now set a timer related to any headline, like an
alarm clock.  Three new commands have been defined:

- org-timer-set-timer :: bound to =C-c C-x ;= in Org buffers
  and to =;= in Org agenda buffers.  This function sets a
  timer for the headline the cursor is currently it.  Up to
  three timers can be used at any time.

- org-timer-show-remaining-time :: Show the remaining time
  for the last timer set.

- org-timer-cancel-timers :: Cancel all timers.

This functionality was requested by Samuel Wales and
emulates that of /tea-time.el/ -- see the emacswiki doc at

      http://www.emacswiki.org/emacs/tea-time

*** Clock reports may include a time stamp

Using =:timetamp t= as an option in a clock report now
allows insertion of the timestamp for the clocked entry.
Timestamps are searched for in this order: =SCHEDULING=,
=TIMESTAMP=, =DEADLINE= and =TIMESTAMP_IA=.

*** New option =org-id-uuid-program=

On some systems, =uuidgen= is named =uuid=.

*** Clock notification handler made configurable

See the variable =org-show-notification-handler=.

*** New option =org-tags-sort-function=.

This allows tags to be sorted by =string<=, =string>=, or a
custom function.

Thanks to James TD Smith for a patch to this effect.

*** Improvements for org-feed.el

But fixes, and allowing to choose between =wget= and =curl=.

Thanks to Christopher League for a patch to this effect.


* Version 6.28
 :PROPERTIES:
 :CUSTOM_ID: v6.28
 :END:


** Agenda changes
*** Refiling now works from the agenda

The command =C-c C-w= can be executed to refile an entry shown in
the agenda.  After the command, the entry will no longer be shown
in the agenda.  It it is still in an agenda file, refresh the
agenda to bring it up from it's new context.

*** Bulk action

You can now use the =m= key to mark entries in the agenda.  =u=
will unmark the etry at point, and =U= will unmark everything.
When one or more entries have been selected, the =B= key will
execute an action on all selected entries.  I believe this bulk
action makes mainly sense for the commands that require answering
interactive prompts.  So far the supported actions are

 - Refile all selected entries to a single destination
 - Archive all selected entries
 - Set the TODO state of all selected entries, bypassing any
   blocking or note-taking.
 - Add or remove a tag to/from all selected entries

We can add more actions, if you convince me they make sense.

*** Modified keys

To make room for the new Bulk action commands, some keys in the
agenda buffer had to move:

There is a new command bound to the =v= key, it dispatches
various view mode changes.  Month and year view are now only
available as =v m= and =v y=, respectively.  Turning on
inclusion of archive trees and files (unsed to be on =v=) is
now on =v a= and =v A=.

** Improvements related to =#+begin= blocks

*** Indented blocks

=#+begin_ ... +#end_...= blocks may now be indented along
with the structure of your document.  So the =#+= lines no
longer need to start in column 0, these lines can be, along
with the block contents, indented arbitrarily.  Org supports
this during editing with "C-c '", and now finally treats them
consistently during export across all backends.  This makes
these blocks work much better with plain list structure
editing, and it also looks better if you like to indent text
under outline headings.  For example:

#+begin_src org
  ,*** This is some headline
  ,    #+begin_example
  ,    here we have an example
  ,    #+end_example
  ,
  ,    - a plain list
  ,      - a sublist item
  ,        - a second sublist item

  ,          #+begin_center
  ,           centering within the plain list item
  ,          #+end_center

  ,      #+begin_example
  ,       This example does terminate the sublist,
  ,       the indentation of the #+begin line counts.
  ,      #+end_example

  ,    - but the top level plain lists continues here
#+end_src

From now on, the indentation of such a block decides whether
it is part of a plain list item or if it is actually
terminating the list.  This was so far inconsistent between
editing behavior and export, now it is consistent.

The content of the block, i.e. the text between the #+ lines
gets an extra indentation of two space characters, which I
find visually pleasing.  You can change the amount of extra
indentation using the variable
=org-src-content-indentation=.

This was a pretty complex change, achieved in many small
steps over the last couple of weeks.  It cleans up one of the
more annoying inconsistencies in Org.  I hope it will work,
but I am sure you will let me know if not.

*** Indented tables

Also tables can be fully indented now.  What is new here is
that the =#+TBLFM= line, and also things like =#+caption=,
=#+label=, =#+attr_...= etc can be indented along with the
table.  Again, this makes the look of the document better and
allows for proper plain list structure editing.

*** Protected blocks

Some =#+begin_ ... +#end_...= blocks contain text that should not
be processed like normal Org-mode text.  =example= and =src=
block fall into this class, and so do =ditaa= blocks, for
example.  The content in such blocks is now properly fontified in
a single face (called =org-block=).  This was a frequently
requested feature.  The list of blocks that should be protected
from normal Org-mode fontification is defined in the variable
=org-protecting-blocks=.  Modules defining new blocks should add
to this variable when needed.  =org-exp-blocks.el= does this
already.

*** Hide and show the contents of blocks

Blocks can now be folded and unfolded with =TAB=.  If you
want to have all blocks folded on startup, customize
=org-hide-block-startup= or use the =#+STARTUP= options
=hideblocks= or =showblocks= to overrule this variable on a
per-file basis.

Thanks to Eric Schulte for a patch to this effect.

*** Moved Eric Schulte's org-exp-blocks.el into the core

This seems to be getting a lot of use now, so it is now part of
the core and loaded automatically.  This package can now also be
used to define new blocks.  Customize the variable
=org-export-blocks= or use the function
=org-export-blocks-add-block=.


** New and updated contributed modules
*** org-export-generic.el is now a contributed package.

This new module allows users to export an Org page to any type of
output by constructing the output using a list of prefixes,
format specifications and suffixes for the various types of org
data (headlines, paragraphs, list bullets, etc).  Use the
=org-set-generic-type= function to define your own export types
and have them bound to a key (use an upper-case letter for user
export definitions).

Thanks to Wes Hardaker for this contribution with a lot of
potential.
*** New contributed modules org-mac-iCal.el by Christopher Suckling

See the [[http://orgmode.org/worg/org-contrib/org-mac-iCal.php][documentation on Worg]].

*** org-jira.el: New file, by Jonathan Arkell

Links to Jira tickets.

*** org-R.el: Updated.

/org-R.el/ has been updated, thanks to Dan Davison for this.

*** =[ TABLE-OF-CONTENTS]= is now also used for LaTeX export

This cookie will mark the location of the =\tableofcontents=
macro.  Triggered by a report by Yuva.


** Changes to the clocking system
*** New option `org-clock-out-switch-to-state'.

Clocking out can now switch the task to a particular state.

This was a request by Manish.

*** More control about what time is shown in mode line while clocking

- If you have an =Effort= property defined, its value is also
  shown in the mode line, and you can configure =org-clock-sound=
  to get an alert when your planned time for a particular item is
  over.

- When an entry has been clocked earlier, the time shown in the
  mode line while the item is being clocked is now the sum of all
  previous, and the current clock.

- The exception to the previous rule are repeating entries: There
  the clock time will only be clocking instances recorded since
  the last time the entry when through a repeat event.  The time
  of that event is now recorded in the =LAST_REPEAT= property

- You can use the property CLOCK_MODELINE_TOTAL to get
  control over what times are displayed in the mode line, see
  the manual for more information.

- The new command =C-c C-x C-e= can be used to change the Effort
  estimate and therefore to change the moment when the clock sound
  will go off.

- The clock string in the modeline now has a special font,
  =org-mode-line-clock=.  This was a proposal by Samuel Wales.

- Clicking on the mode line display of the clock now offers a
  menu with important clock functions like clocking out, or
  switching the clock to a different task.

Thanks to Konstantin Antipin for part of the implementation, and
thanks to Bernt Hansen for helping to iron out the issues related
to repeated tasks.


** Miscellaneous changes

*** Allow to specify the alignment in table columns by hand

Similar to the =<20>= cookies that allow to specify a maximum
width for a table column, you can now also specify the alignment
in order to overrule the automatic alignment choice based on the
dominance of number or non-number fields in a column.  The
corresponding cookies are =<l>= and =<r>= for left and right side
alignment, respectively.  These can be combined with maximum
width specification like this: =<r15>=.

This was a proposal by Michael Brand.

*** Stop logging and blocking when selecting a TODO state

Sometimes you want to quickly select or change a TODO state of an
item, without being bothered by your setup for blocking state
changes and logging entries.  So in this case, you don't want the
change be seen as a true state change.

You can now set the variable
=org-treat-S-cursor-todo-selection-as-state-change= to nil.
Then, when you use =S-left= and =S-right= to quickly flip through
states, blocking and logging will be temporarily disabled.

*** Export BBDB anniversaries to iCalendar

See the variable `org-icalendar-include-bbdb-anniversaries'.

This was a request by Richard Riley, thanks to Thomas Baumann
for the prompt implementation.

*** Macro definitions can be collected in an #+SETUPFILE

If you want to use many macros in different files, collect the
=#+macro= lines into a file and link to them with

: #+SETUPFILE: path/to-file

*** Subtree cloning now also shifts inactive dates

When using the command =org-clone-subtree-with-time-shift=, time
stamps will be shifted for each clone.  So far, this applied only
to active timestamps, but now it does apply to inactive
ones as well.

*** HTML table export: Assign alternating classes to rows

The new variable =org-export-table-row-tags= can now be set up in
a way so that different table lines get special CSS classes
assigned.  This can be used for example to choose different
background colors for odd and even lines, respectively.  The
docstring of the variable contains this example:

#+begin_src emacs-lisp
  (setq org-export-table-row-tags
        (cons '(if head
               "<tr>"
             (if (= (mod nline 2) 1)
                 "<tr class=\"tr-odd\">"
               "<tr class=\"tr-even\">"))
          "</tr>"))
#+end_src

It makes use of the local variables =head= and =nline= which are
used to check whether the current line is a header line, and whether
it is an odd or an even line.  Since this is fully programmable,
you can do other things as well.

This was a request by Xin Shi.

*** Remember: target headline may be a function

When setting up remember templates, the target headline may now
be a function, similarly to what is allowed for the target file.
The functions needs to return the headline that should be used.

*** Remove flyspell overlays in places where they are not wanted

We now keep flyspell from highlighting non-words in links.

*** Update targets in the Makefile

Some new targets in the default Makefile make it easier to update
through git to the latest version: =update= and =up2=.  Here are
the definitions.

#+begin_src BSDmakefile
update:
        git pull
        ${MAKE} clean
        ${MAKE} all

up2:    update
        sudo ${MAKE} install
#+end_src

This was a request by Konstantin Antipin.

* Version 6.27
  :PROPERTIES:
  :CUSTOM_ID: v6.27
  :END:

** Details

*** Macros for export

Macro processing for export has been enhanced:

- You can use arguments in a macro, for example
#+begin_src org
#+macro hello Greet the $1: Hello $1
#+end_src
  which would turn ={{{hello(world)}}}= into =Greet the world: Hello world=

- The macro value can be an emacs-lisp for to be evaluated at the
  time of export:

#+begin_src org
,#+macro: datetime (eval (format-time-string "$1"))
#+end_src

- More built-in default macros:
  - date(FORMAT_TIME_STRING) :: Time/Date of export
  - time(FORMAT_TIME_STRING) :: Same as date
  - modification-time(FORMAT_TIME_STRING) :: Last modification of file
  - input-file :: Name of the input file

  The new built-in macros have been requested by Daniel Clemente.

*** Link completion for files and bbdb names

Org now has a general mechanism how modules can provide enhanced
support (for example through completion) when adding a link.  For
example, when inserting a link with =C-c C-l=, you can now type
=file:= followed by =RET= to get completion support for inserting
a file.  After entering =bbdb:= and =RET=, a completion interface
will allow to complete names in the BBDB database.  These are the
only ones implemented right now, but modules that add a link type
=xyz:= can simple define =org-xyz-complete-link= that should
return the full link with prefix after aiding the used to create
the link.  For example, if you have =http= links that you have to
insert very often, you could define a function
=org-http-complete-link= to help selecting the most common ones.

*** Source file publishing

It is now easy to publish the Org sources along with, for
example, HTML files.  In your publishing project, replace

: :publishing-function org-publish-org-to-html

with

:  :publishing-function (org-publish-org-to-html org-publish-org-to-org)
:  :plain-source t
:  :htmlized-source t

to get both the plain org file and an htmlized version that
looks like your editing buffer published along with the HTML
exported version.

*** Push exported stuff to kill ring

All exporters now push the produced material onto the kill-ring
in Emacs, and also to the external clipboard and the primary
selection to make it easy to paste this under many circumstances.

*** Tables in LaTeX without centering
Set the variable `org-export-latex-tables-centered' to nil if you
prefer tables not to be horizontally centered.  Note that
longtable tables are always centered.

*** LaTeX export: TODO markup configurable

The markup for TODO keywords in LaTeX export is now configurable
using the variable =org-export-latex-todo-keyword-markup=.

*** ASCII export to buffer

ASCII export has now the same command variations as the other
export backends, for example exporting to a temporary buffer
instead of a file.

The was a request by Samuel Wales.

*** Accessibility improvements for HTTP tables

When exporting tables to HTML, Org now adds =scope= attributes to
all header fields, in order to support screen readers.
Setting the variable
=org-export-html-table-use-header-tags-for-first-column= will
request using =<th>= instead of =<td>= also in the entire first
column, so that also row information can be scoped.  This was
triggered by a request by Jan Buchal, and as usually Sebastian
Rose came up with the right implementation.

*** Timezone information in iCalendar files

The timezone information in iCalendar files is now written in the
correct format, and can be set in the variable
=org-ical-timezone=.  This variable is initialized from the =TZ=
environment variable.

*** New contributed package /org-special-blocks.el/

The package turns any "undefined" =#+begin_...= blocks into LaTeX
environments for LaTeX export, and into =<div>= tags for HTML
export.

Thanks to Chris Gray for this contribution.

*** More flexibility about placing logging notes.

Logging into a drawer can now also be set for individual
subtrees using the =LOG_INTO_DRAWER= property.

Requested by Daniel J. Sinder

*** New reload key

Reloading Org has moved to a new key, =C-c C-x !=, and is now
also available in the agenda.

*** Start Agenda with log mode active
Set the new option =org-agenda-start-with-log-mode= to have
log mode turned on from the start.  Or set this option for
specific custom commands.

Thanks to Benjamin Andresen for a patch to this effect.

*** Agenda speed optimizations

Depending on circumstances, construction the agenda has become a
lot faster.

Triggered by Eric S Fraga's reports about using Org on a slow
computer like a netbook.

*** New face for today in agenda

The date that is today can now be highlighted in the agenda by
customizing the face =org-agenda-date-today=.

Thanks to Dmitri Minaev for a patch to this effect.

*** Properties to disambiguate statistics

When an entry has both check boxes and TODO children, it is not
clear what kind of statistics a cookie should show  You can now use
the =COOKIE_DATA= property to disambiguate, by giving it a value
"todo" or "checkbox".

Thanks to Ulf Stegeman, who was persistent enough to push this
change past my initial resistance.

*** Checkboxes and TODO items: recursive statistics

Setting the variable =org-hierarchical-checkbox-statistics= to
=nil= will make statistics cookies count all checkboxes in the
lit hierarchy below it.

Setting the variable =org-hierarchical-todo-statistics= to
=nil= will do the same for TODO items.

To turn on recursive statistics only for a single subtree, add the
word "recursive" to the =COOKIE_DATA= property.  Note that you
can have such a property containing both "todo" or "checkbox" for
disambiguation, and the word "recursive", separated by a space
character.

The change for checkboxes was a patch by Richard Klinda.

*** New operators for column view

Column view has new operators for computing the minimum,
maximum, and mean of property values.

Thanks to Mikael Fornius for a patch to this effect.

* Version 6.26
  :PROPERTIES:
  :CUSTOM_ID: v6.26
  :END:

** Details

*** custom IDs

Entries can now define a =CUSTOM_ID= property.  This property
must be a valid ID according to HTML rules, and it will be used
in HTML export as the main target ID for this entry.  That means,
both the table of conents and other internal links will
automatically point to this ID instead of the automatic ID like
=sec-1.1=.  This is useful to create humar-readable permanent
links to these location in a document.

The user is responsible to make sure that  custom IDs are unique
within a file.

Links written like =[[#my-target-name] ]= can be used to target a
custom ID.

When using =C-c l= to store a link to a headline that has a
custom ID, Org will now create two links at the same time.  One
link will be to the custom ID.  The other will be to the globaly
unique ID property.  When inserting the line with =C-c C-l=, you
need to decide which one you want to use.  Use the ID links for
entries that are expected to move from one file to the next.  Use
custom ID links publishing projects, when you are sure that te
entry will stay in that file.  See also the variable
=org-link-to-org-use-id=.

*** Remember to non-org files

If the target headline part of a remember template definition
entry is =top= or =bottom=, the target file may now be a
non-Org-mode file.  In this case, the content of the remember
buffer will be added to that file without enforcing an Org-like
headline.  Sorry, Russel, that this took so long.

*** New property to turn off todo dependencies locally

Setting the property =NOBLOCKING= will turn off TODO dependency
checking for this entry.

*** Refile verify

A new function is called to verify tasks that are about to be
selected as remember targets.  See the new variable
=org-refile-target-verify-function=.

*** New version org ditaa.jar

Thanks to Stathis Sideris.

*** htmlize.el is now in the contrib directory

The latest version of htmlize.el is now the in the contrib
directory of Org.  Thanks to Hrvoje Niksic for allowing this.

* Version 6.25
  :PROPERTIES:
  :CUSTOM_ID: v6.25
  :END:

** Major new features

*** DocBook export

We now do have a fully functional DocBook exporter, contributed by
Baoqiu Cui.  Simple press =C-c e D= to export the current file to
DocBook format.  You can also get direct conversion to PDF if you have
made the correct setup, please see the manual for details.

Kudos to Baoqiu for this fantastic addition, and my personal thanks
for doing this in a such a smooth way that I did not have to do
anything myself.

*** Protocols for external access to Emacs and Org

/org-protocol.el/ is a new module that supersedes both
/org-annotation-helper.el/ and /org-browser.el/ and replaces them
with a more abstracted interface.  /org-protocol/ intercepts
calls from emacsclient to trigger custom actions without external
dependencies.  Only one protocol has to be configured with your
external applications or the operating system, to trigger an
arbitrary number of custom actions. Just register your custom
sub-protocol and handler with the new variable
=org-protocol-protocol-alist=.

org-protocol comes the with three standard protocol handlers (in
parenthesis the name of the sub-protocol):
- =org-protocol-remember= (=remember=) :: Trigger remember
- =org-protocol-store-link= (=store-link=) :: Store a link
- =org-protocol-open-source= (=open-source=) :: Find the local
     source of a remote web page.

Passing data to emacs is now as easy as calling

: emacsclient org-protocol://sub-protocol://data

For more information see the [[http://orgmode.org/worg/org-contrib/org-protocol.php][online documentation]]

Thanks to Sebastian Rose for this really beautiful module.

*** Inline tasks

Inline tasks are tasks that have all the properties of normal
outline nodes, including the ability to store meta data like
scheduling dates, TODO state, tags and properties.  But these
tasks are not meant to introduce additional outline structure, at
least as far as visibility cycling and export is concerned.  They
are useful for adding tasks in extensive pieces of text where
interruption of the flow or restructuring is unwanted.

This feature is not turned on by default, you need to configure
=org-modules= to turn it on, or simply add to you .emacs file:

: (require 'org-inlinetask)

After that, tasks with level 15 (30 stars when using
org-odd-levels-only) will be treated as inline tasks, and
fontification will make obvious which tasks are treated in this
way.

*** Input from RSS feeds

Org can now collect tasks from an RSS feed, a great method to get
stuff from online call and note-taking services into your trusted
system.  You need to configure the feeds in the variable
=org-feed-alist=.  The manual contains a short description, more
detailed information is [[http://orgmode.org/worg/org-contrib/org-feed.php][available on Worg]].

Full credit goes to Brad Bozarth who really [[http://thread.gmane.org/gmane.emacs.orgmode/12251][paved the way]] for this
exciting new feature.


** Export

*** Allow modification of table attributes in HTML export

The #+ATTR_HTML line can now be used to set attributes for a
table.  Attributes listed in that line will replace existing
attributes in =org-export-html-table-tag=, or will add new ones.
For example

: #+ATTR_HTML: border="2" rules="all" frame="all"
: #+CAPTION: Finally a table with lines!
: | a | b |
: |---|---|
: | 1 | 2 |

*** LaTeX low levels are now exported as itemize lists

LaTeX export now treats hierarchy levels 4,5, etc as itemize
lists, not as description lists as before.  This is more
consistent with the behavior of HTML export.  You can configure
this behavior using the variable =org-export-latex-low-levels=.

*** Markup for centering.

Text can be exported centered with

#+begin_src org
,#+BEGIN_CENTER
,Everything should be made as simple as possible, \\
,but not any simpler
,#+END_CENTER
#+end_src

*** Sitemap file is now /sitemap.org/

Org-publish can produce a list of all files in a project.
Previously the file containing this list was called "index.org",
really a brain-dead default because during publication it would
overwrite the "index.html" file of the website.

The default file name is now "sitemap.org"

*** Protect explicit target links in HTML export

If a link is =[[#name] [desc]]=, the href produced when exporting
the file will be exactly href="#name".  So starting a link target
with # will indicate that there will be an explicit target for
this.

*** HTML export: Allow "- ___" to explicitly terminate a list

If a list contains "- ___" (three underscores) as an item, this
terminates the list, ignoring this item.  This is an experimental
feature, it may disappear again if we find other ways to deal
with literal examples right after lists.

See [[http://thread.gmane.org/gmane.emacs.orgmode/12299/focus%3D12312][this mailing list thread]] for context.

** Agenda

*** Changing the time of an entry from the agenda

We now have a way to change not only the date, but also the start
time of an entry from the agenda.  The date is normally changed
with S-right/left.  Now, if you add a C-u prefix, the hour will
be changed.  If you immediately press S-right/left again, hours
will continue to be changed.  A double prefix will do the same
for minutes.  If the entry has a time range like 14:40-16:00,
then both times will change, preserving the length of the
appointment.

*** Show saved PDF agenda view with prefix arg

When writing an agenda view to a PDF file, supplying a a prefix
argument (=C-u C-x C-w=) will get the new file displayed
immediately.

This was a request by Alan E Davis.

*** Filter for entries with no effort defined

During secondary agenda filtering, pressing "?" now will install a
filter that selects entries which do not have an effort defined.

This new model was necessary because we needed to stop interpreting
entries with no effort defines as 0 effort.  This was inconsistent,
because for normal agenda sorting, the treatment of these entries
depends on the variable =org-sort-agenda-noeffort-is-high=.  Now this
variable is also respected during filtering.

This new feature resulted from a [[http://thread.gmane.org/gmane.emacs.orgmode/12493][discussion]] with Matt Lundin and
Bernt Hansen.

*** Introduce user-defined sorting operators

The new variable =org-agenda-cmp-user-defined= can contain a
function to test how two entries should be compared during
sorting.  The symbols =user-defined-up= and =user-defined-down=
can then be part of any sorting strategy.

This was a request by Samuel Wales.

*** Indentation of subitems in the agenda

When a tags/property match does match an entry and it's
sublevels, the sublevels used to be indented by dots, to indicate
that the matches likely result from tag inheritance.  This is now
no longer the default, so the subitems will not get special
indentation.  You can get this behavior back with

: (setq org-tags-match-list-sublevels 'indented)

*** Stuck projects search now searches subtrees of unstuck projects

When, during a stuck-project search, a project tree is identified
as not stuck, so far the search would continue after the end of
the project tree.  From now on, the search continues in the
subtree, so that stuck subprojects can still be identified.


** Miscellaneous

*** Citations: Use RefTeX to insert citations

RefTeX can now be used to create a citation in Org-mode buffers.
Setup the buffer with

#+begin_src org
,#+BIBLIOGRAPHY: bibbase style
#+end_src

and create citations with =C-c C-x [=.

Together with org-exp-bibtex.el by Taru Karttunen (available as a
contributed package), this provides a great environment for
including citations into HTML and LaTeX documents.

*** Changing time ranges as a block

When using the S-cursor keys to change the first time in a time
range like

: <2009-04-01 Wed 14:40-16:40>

then the end time will change along, so that the duration of the
event will stay the same.

This was a request by Anupam Sengupta.

*** New sparse tree command

A new sparse tree command shows entries with times after a certain
date.  Keys are =C-c / a=, this command is for symmetry
with =C-c / b=.

*** Cloning tasks

A new command allows to create clone copies of the current entry,
with shifted dates in all stamps in the entry.  This is useful to
create, for example, a series of entries for a limited time
period.  I am using it to prepare lectures, for example.

*** New face for checkboxes

Checkboxes now have their own face, =org-checkbox=.  This can be
used for nice effects, for example choosing a face with a box
around it:

#+begin_src emacs-lisp
(custom-set-faces
 (org-checkbox ((t (:background "#444444" :foreground "white"
                :box (:line-width 1 :style released-button)))))
#+end_src

*** M-a and M-e for navigation in a table field

In tables fields, the sentence commands =M-a= and =M-e= are
redefined to jump to the beginning or end of the field.

This was a request by Bastien Guerry.

*** Backup files for remember buffers

Sometimes users report that they lost data when not immediately
storing a new remember note, and then later exiting Emacs or
starting a new remember process.

Now you can set the variable =org-remember-backup-directory=.
Each remember buffer created will then get its own unique file
name in that directory, and the file will be removed only if the
storing of the note to an Org files was successful.

*** org-mac-message.el: New functions to access flagged mail

Christopher Suckling has added functionality to
/org-mac-message.el/.  In particular, you can now select a number
of messages and easily get links to all of them with a single
command.  For details, see the [[http://orgmode.org/worg/org-contrib/org-mac-message.php][online documentation]].

*** Read-date: New hook

The new hook =org-read-date-minibuffer-setup-hook= is called when
setting up the minibuffer for reading a date.  If can be used to
install new keys into the temporary keymap used there.


* Version 6.24
  :PROPERTIES:
  :CUSTOM_ID: v6.24
  :END:

** Incompatible changes


*** Tag searches are now case-sensitive

From this release on, tag searches will be case sensitive.  While
I still think it would be nice to have them case-insensitive,
this was both an inconsistency (TODO keyword searches have always
been case-sensitive), and trouble for coding some efficient
algorithms.  So please make sure that you give the tags with
correct casing when prompted for a match expression.

*** New key for creating tags/property sparse trees

The key to produce a sparse tree matching tags and properties is
now =C-c / m= instead of =C-c a T=.  This is also more consistent
with the =C-c a m= key for the corresponding agenda view.
=C-c / T= will still work for now, but it is no longer advertised
in the documentation and may go away at any time in the future.

*** IDs in HTML have "ID-" prefix when generated by uuidgen

/uuidgen/ generates IDs that often start with a number, not a
latter.  However, IDs and names in XHTML must start with a letter.
Therefore, IDs in HTML files will now get an "ID-" prefix if they
have been generated by uuidgen.  This means that id links from one
file to another may stop working until all files have been
exported again.

*** In agenda, only priority cookies get the special face

So far, an entire task would get a special face when
=org-agenda-fontify-priorities= was set.  Now, the default value
for this variable is the symbol =cookies=, which means that on
the cookie is fontified.  Set it to =t= if you want the entire
task headline to be fontified.

** Details

*** PDF export of agenda views

Agenda views can now be exported to PDF files by writing them to
a file with extension ".pdf".  Internally this works by first
producing the postscript version and then converting that to PDF
using the ghostview utility =ps2pdf=.  Make sure that this
utility is installed on your system.

The postscript version will not be removed, it will stay around.

*** Inline some entry text for Agenda View export

When exporting an agenda view to HTML or PDF for printing or
remote access, one of the problems can be that information stored
in entries below the headline is not accessible in that format.

You can now copy some of that information to the agenda view
before exporting it.  For this you need to set the variable
=org-agenda-add-entry-text-maxlines= to a number greater than 0.

#+begin_src emacs-lisp
(setq org-agenda-add-entry-text-maxlines 20)
#+end_src

Or you can do this with the settings in a custom agenda view,
for example

#+begin_src emacs-lisp
("A" "" agenda ""
 ((org-agenda-ndays 1)
  (org-agenda-add-entry-text-maxlines 5))
 ("agenda-today.pdf"))
#+end_src

*** Improved ASCII export of links

ASCII export of links works now much better.  If a link has a
link and a description part which are different, then the
description will remain in the text while the link part will be
moved to the end of the current section, before the next heading,
as a footnote-like construct.

Configure the variable =org-export-ascii-links-to-notes= if you
prefer the links to be shown in the text.  In this case, Org will
make an attempt to wrap the line which may have become
significantly longer by showing the link.

Thanks to Samuel Wales for pointing out the bad state of ASCII
link export.

*** Custom agenda commands can specify a filter preset

If a custom agenda command specifies a value for
=org-agenda-filter-preset= in its options, the initial view of
the agenda will be filterd by the specified tags.  Applying a
filter with =/= will then always add to that preset filter,
clearing the filter with =/ /= will set it back to the preset.
Here is an example of a custom agenda view that will display the
agenda, but hide all entries with tags =FLUFF= or =BLUFF=:

#+begin_src emacs-lisp
("A" "" agenda ""
 ((org-agenda-filter-preset '("-FLUFF" "-BLUFF"))))
#+end_src

This is in response to a [[http://thread.gmane.org/gmane.emacs.orgmode/11752][thread on the mailing list]], started by
Daniel Clemente and with great contributions by Bernt Hansen and
Matt Lundin.

*** Exporting of citations to LaTeX and HTML, using BibTeX

Citations can now me made using BibTeX, and will be exported to
LaTeX and HTML.  This is implemented in a contributed package by
Taru Karttunen, /org-exp-bibtex.el/.  Kudos to Taru for this
really nice addition.

*** Finally a way to specify keywords and description for HTML export

Use something like

#+begin_src org
#+DESCRIPTION: This page is all about ....
#+KEYWORDS: org-mode, indexing, publishing
#+end_src

To specify the content of the description and keywords meta tags
for HTML output.

*** org-collector.el is now a contributed package

/org-collector.el/ provides functions to create tables by
collecting and processing properties from entries in a specific
scope like the current tree or file, or even from all agenda
files.  General lisp expressions can be used to manipulate the
property values before they are inserted into an org-mode table,
for example as a dynamic block that is easy to update.

Thanks to Eric Schulte for yet another great contribution to
Org.

*** Update of org2rem.el

/org2rem.el/ has been updated significantly and now does a more
comprehensive job of exporting Org events to remind.

Thanks to Sharad Pratap for this update.

*** New div around the entire page in HTMP export

A new =<div id=content>= is wrapped around the entire page,
everything that is inside =<body>=.

This means that you need to update /org-info.js/ (if you have a
local copy).  It will be safe todo so, because the new
org-info.js still handles older pages correctly.  Thanks to
Sebastian Rose for making these changes so quicky.

*** Clustering characters for undo

When typing in Org-mode, undo will now remove up to 20 characters
at a time with a single undo command.  This is how things work
normally in Emacs, but the special binding of characters in
Org-mode made this impossible until now.

Thanks to Martin Pohlack for a patch which mimicks the behavior
of the Emacs command loop for the Org version of
=self-insert-command=.  Note that this will not work in headlines
and tables because typing there will do a lot of extra work.

There might be a small typing performance hit resulting from this
change - please report in the mailing list if this is noticeable
and annoying.

*** Separate settings for special C-a and C-e

The variable `org-special-ctrl-a/e' now allows separate settings
for =C-a= and =C-e=.  For example

#+begin_src emacs-lisp
(setq org-special-ctrl-a/e '(reversed . t))
#+end_src

Thanks to Alan Davis for this proposal.

*** orgstruct++-mode improvements

In addition to =orgstruct-mode= which allows to use some Org-mode
structure commands in other major modes, there is a more invasive
version of this mode: =orgstruct++-mode=.  This mode will import
all paragraph and line wrapping variables into the major mode, so
that, for example, during typing the auto-fill wrapping of items
will work just like in Org-mode.  This change is not reversible,
so turning off =orgstruct++-mode= will not remove these settings
again. =orgstruct++-mode= is most useful in text modes like
message-mode or =magit-log-edit-mode=.  Furthermore,
=orgstruct++-mode= will recognize plain list context not only in
the first line of an item, but also further down, so that =M-RET=
will correctly insert new items.

Thanks to Austin Frank for requesting some of these changes.

*** Promotion and demotion works for regions now

=M-right= and =M-left= now do demote and promote all headlines in
an active region.

*** Match syntax for tags/properties is now described in a single place

The manual chapters about tags and about properties now only
refer to the section about agenda views, where the general syntax
of tag/property matches is described.

*** Macro replacement

A string like ={{{ title }}}= will be replaced by the title of
the document, ={{{ email }}}= by the email setting of the author
and similarly for other export settings given in =#+...= lines.
In addition to that, you can define an arbitrary number of
macros, for example:

#+begin_src org
,#+MACRO: myaddress 41 Onestreet, 12345 New York, NY
...
,my address is {{{myaddress}}}, see you there.
#+end_src

Macro replacement is the very first thing that happens during
export, and macros will be replaced even in source code and other
protected regions.

*** New reload command, with keyboard access

There is now a special command to reload all Org Lisp files, so
that you can stay in your Emacs session while pulling and
compiling changes to Org.  The command to reload the compiled
files (if available) is =C-c C-x r=.  If no compiled files are
found, uncompiled ones will be loaded.  If you want to force
loading of uncompiled code (great for producing backtraces), use
a prefix arg: =C-u C-c C-x r=.  Both commands are available in
the menu as well.

This new command was inspired by one written earlier by Bernt
Hansen.

*** Faces for priority cookies can now be set freely

The new variable =org-priority-faces= can be used to set faces
for each priority.

*** New key for creating tags/property sparse trees

The key to produce a sparse tree matching tags and properties is
now =C-c / m= instead of =C-c a T=.  This is more consistent with
the =C-c a m= key for the corresponding agenda view.  =C-c / T=
will still work for now, but it is no longer advertised in the
documentation and may go away at any time in the future.

*** IDs in HTML have "ID-" prefix when generated by uuidgen

/uuidgen/ generates IDs that often start with a number, not a
letter.  However, IDs and names in XHTML must start with a letter.
Therefore, IDs in HTML files will now get an "ID-" prefix if they
have been generated by /uuidgen/.  This means that id links from one
file to another may stop working until all files have been
exported again, so that both links and targets have the new prefix.

*** In agenda, only priority cookies get the special face

So far, an entire task would get a special face when
=org-agenda-fontify-priorities= was set.  Now, the default value
for this variable is the symbol =cookies=, which means that on
the cookie is fontified.  Set it to =t= if you want the entire
task headline to be fontified.

*** Turning off time-of-day search in headline

Some people like to put a creation time stamp into a headline and
then get confused if the time-of-day found in there shows up as
the time-of-day of the deadline/scheduling entry for this
headline.  The reason for this is that Org searches the headline
for a free-format time when trying to sort the entry into the
agenda, and that search accidentally finds the time in the
creation time stamp or something else that happens to look like a
time.  If this is more painful than useful for you, configure the
new variable =org-agenda-search-headline-for-time=.


* Version 6.23
  :PROPERTIES:
  :CUSTOM_ID: v6.23
  :END:

** Incompatible changes

- CLOCK lines will now be captured into the LOGBOOK drawer.
  See below for details.

** Details

*** Capture state change notes into a drawer

State change notes can now be captured into a drawer =LOGBOOK=,
to keep the entry tidy.  If this is what you want, you will need
this configuration:

#+begin_src emacs-lisp
(setq org-log-into-drawer "LOGBOOK")
#+end_src

Thanks to Wanrong Lin for this proposal.

*** Clock lines are now captured into the LOGBOOK drawer as well

The =CLOCK= drawer will be abandoned, clock lines will now also
end up in a drawer =LOGBOOK=.  The reason for this is that it's a
bit useless to have two different drawers for state change notes
and clock lines.  If you wish to keep the old way, use

#+begin_src emacs-lisp
(setq org-clock-into-drawer "CLOCK")
#+end_src

*** Added org-R.el to contrib directory

Dan Davison has contributed /org-R.el/ which is now in the
contrib directory.  Org-R performs numerical computations and
generates graphics.  Data can come from org tables, or from csv
files; numerical output can be stored in the org buffer as org
tables, and links are created to files containing graphical
output.  Although, behind the scenes, it uses R, you do not need
to know anything about R.  Common operations, such as tabulating
discrete values in a column of an org table, are available "off
the shelf" by specifying options on lines starting with =#+R:=.
However, you can also provide raw R code to be evaluated.  The
documentation is currently the worg tutorial at
http://orgmode.org/worg/org-tutorials/org-R/org-R.php

Thanks to Dan for this great contribution.

*** Allow individual formatting of TODO keyword and tags in HTML export

TODO keywords in HTML export have the CSS class =todo= or =done=.
Tags have the CSS class =tag=.  In addition to this, each keyword
has now itself as class, so you could do this in your CSS file:

#+begin_src css
.todo { font-weight:bold; }
.done { font-weight:bold; }
.TODO { color:red; }
.WAITING { color:orange; }
.DONE { color:green; }
#+end_src

If any of your keywords causes conflicts with CSS classes used
for different purposes (for example a tag "title" would cause a
conflict with the class used for formatting the document title),
then you can use the variables =org-export-html-tag-class-prefix=
and =org-export-html-todo-kwd-class-prefix= to define prefixes
for the class names for keywords, for example "kwd-".

Thanks to Wanrong Lin for this request, and to Sebastian Rose for
help with the implementation.

*** New hooks for add-ons to tap into context-sensitive commands

Some commands in Org are context-sensitive, they will execute
different functions depending on context.  The most important
example is of course =C-c C-c=, but also the =M-cursor= keys fall
into this category.

Org has now a system of hooks that can be used by add-on packages
to install their own functionality into these keys.  See the
docstring of =org-ctrl-c-ctrl-c-hook= for details.  The other
hooks are named like =org-metaleft-hook= or
=org-shiftmetaright-hook=.

*** Publishing files irrespective of extension

If you set the =:base-extension= property for a publishing
project to the symbol =any=, all files in the directory will be
published, irrespective of extension.

Thanks to Richard Klinda for a patch to this effect.

*** New variable index in the manual

A new index in the manual lists all variables mentioned in the
manual, about 200 variables in total.

*** The ORDERED property also influences checkboxes

When an entry has the ORDERED property set, checkboxes in
the entry must be completed in order.  This was already the case
for children TODO items, now it also applies for checkboxes.

Thanks to Rainer Stengele for this proposal.

*** The ORDERED property can be tracked with a tag

The =ORDERED= property is used to flag an entry so that subtasks
(both children TODO items and checkboxes) must be completed in
order.  This property is most easily toggled with the command
=C-c C-x o=.  A property was chosen for this functionality,
because this should be a behavior local to the current task, not
inherited like tags.  However, properties are normally
invisible.  If you would like visual feedback on the state of
this property, configure the variable
=org-track-ordered-property-with-tag=.  If you then use =C-c C-x
o= to toggle the property, a tag will be toggled as well, for
visual feedback.

Note that the tag itself has no meaning for the behavior of TODO
items and checkboxes, and that changing the tag with the usual
tag commands will not influence the property and therefore the
behavior of TODO and checkbox commands.

*** You may now specify line breaks in the fast tags interface

Up to now, the fast tags interface tried to lump as many tags as
possible into a single line, with the exception that groups would
always be on a line by themselves.

Now, if you use several lines to define your tags, like

#+begin_src org
,#+TAGS: aa(a) bb(b) cc(c)
,#+TAGS: dd(d) ee(e) ff(f)
#+end_src

then there will also be a line break after the "cc" tag in the
fast tag selection interface.  You may also write

#+begin_src org
,#+TAGS: aa(a) bb(b) cc(c) \n dd(d) ee(e) ff(f)
#+end_src

to achieve the same effect, and you can use =\n= several times in
order to produce empty lines.  In =org-tag-alist=, newlines are
represented as =(:newline)=.

Thanks to Christopher Suckling for a patch to this effect.

*** When a TODO is blocked by checkboxes, keep it visible in agenda

When the variable =org-agenda-dim-blocked-tasks= is set to
=invisible=, tasks that are blocked will not be visible in the
agenda.  If the blocking is due to child TODO entries, this does
make sense because the children themselves will show up in the
TODO list.

However, as John Rakestraw has [[http://thread.gmane.org/gmane.emacs.orgmode/10939][pointed out]], if the blocking is
done by checkboxes, no trace of these subtasks is left.
Therefore, when the blocking is done by checkboxes, we now
overrule the =invisible= setting and replace it with mere dimming
of the task.

*** LaTeX can import Org's in-buffer definitions for TITLE, EMAIL etc.

If you configure =org-export-latex-import-inbuffer-stuff=,
in-buffer definitions like #+TITLE will be made available in the
LaTeX file as =\orgTITLE=.

This was a request by Russel Adams.

* Version 6.22
  :PROPERTIES:
  :CUSTOM_ID: v6.22
  :END:
** Details

*** org-choose.el by Tom Breton is now included

Org-choose helps documenting a decision-making process by using
TODO keywords for different degrees of /chosenness/, and by
automatically keeping a set of alternatives in a consistent state.

Documentation for /org-choose.el/ is available [[http://orgmode.org/worg/org-contrib/org-choose.php][here]].

This package inserts itself into Org using hooks, so if other
people would like to do interesting stuff with TODO keywords for
special purposes, looking at Tom's code might be a good way to
start.

Thanks to Tom for this interesting contribution!

*** orgmode.org and Worg css works now better on IE

Thanks to Sebastian Rose for making these changes.

*** When exporting a subtree, headline levels are now relative to parent

This was reported as a bug by William Henney and is fixed now.

*** Inactive dates in tables can be used for sorting.

When sorting table fields or entries by date, Org first tries to
find an active date, and, if none exist, uses a passive date if
present.

This was a request by Hsui-Khuen Tang

*** The default for =org-return-follows-link= is back to =nil=

Setting it to =t= violates Emacs rules to some extent.  The
internal implementation of this has been improved, so setting it
to =t= should now be pretty stable.

*** Automatic scheduling of siblings with org-depend.el

The sibling of a DONE task can now automatically be scheduled.

This was a patch by Andrew Hyatt.

*** New skipping conditions

The functions =org-agenda-skip-entry-if= and
=org-agenda-skip-subtree-if= now accept =timestamp= and
=nottimestamp= as additional conditions.

This was in response to a request by Saurabh Agrawal.

* Version 6.21

*** Support for simple TODO dependencies

John Wiegley's code for enforcing simple TODO dependencies has
been integrated into Org-mode.  Thanks John!

The structure of Org files (hierarchy and lists) makes it easy to
define TODO dependencies.  A parent TODO task should not be
marked DONE until all subtasks (defined as children tasks) are
marked as DONE.  And sometimes there is a logical sequence to a
number of (sub)tasks, so that one task cannot be acted upon
before all siblings above it are done.  If you customize the
variable =org-enforce-todo-dependencies=, Org will block entries
from changing state while they have children that are not DONE.
Furthermore, if an entry has a property =ORDERED=, each of its
children will be blocked until all earlier siblings are marked
DONE.  Here is an example:

#+begin_src org
,* TODO Blocked until (two) is done
,** DONE one
,** TODO two

,* Parent
,  :PROPERTIES:
,    :ORDERED: t
,  :END:
,** TODO a
,** TODO b, needs to wait for (a)
,** TODO c, needs to wait for (a) and (b)
#+end_src

The command =C-c C-x o= toggles the value of the =ORDERED=
property.

The variable =org-agenda-dim-blocked-tasks= controls how blocked
entries should appear in the agenda, where they can be dimmed or
even made invisible.

Furthermore, you can use the variable
=org-enforce-todo-checkbox-dependencies= to block TODO entries
from switching to DONE while any checkboxes are unchecked in the entry.

*** Support for shift-selection in Emacs 23

Customize the variable =org-support-shift-select= to use S-cursor
key for selecting text.  Make sure that you carefully read the
docstring of that variable first.

*** Adding and removing checkboxes from many lines

The command =C-c C-x C-b= normally toggles checkbox status in the
current line, or in all lines in the region.  With prefix
argument it now either adds or removes the checkbox.

This was a requested by Daniel Clemente.
