7 This file documents important user-visible changes in gEDA/gaf. For
8 more information, please consult the `ChangeLog' file.
10 Notable changes in gEDA/gaf 1.7.2
11 =================================
13 * `geda-gaf' now requires GTK+ 2.16.0 or later.
15 * A greatly expanded Scheme API has been added to gEDA/gaf for use by
16 extension authors. See the `geda-scheme' Info manual for more
17 details. Existing extensions may need to be modified to load the
18 `(geda deprecated)' or `(gschem deprecated)' modules.
20 * `gschem' keybinding improvements:
22 - Keybindings are now unaffected by Caps Lock.
24 - Keystrokes are displayed using the same characters as on keycaps
25 (e.g. `:' instead of `colon').
27 - Keystrokes may use extended modifiers (Super, Hyper and Meta).
29 - Key bindings can be modified in any rc file or interactively using
30 the `global-set-key' function. See notes in `system-gschemrc' for
33 * `gschem' now displays help files and component documentation on all
34 platforms, including Windows. The `locate' tool is no longer used
35 to search for component documentation files.
37 * The `schdiff' tool for generating visual diffs of schematics and
38 symbols has been added. It can be used with most version control
39 systems. See `man schdiff' for more details.
41 * The `bom' and `bom2' backends to `gnetlist' now give error messages
42 if no attribute file can be found. The `-O attrib_file=FILE' and
43 `-O attribs=ATTRIB,ATTRIB...' options have also been added.
45 * A new `ewnet' backend has been added to `gnetlist'. This outputs
46 netlists for use with the National Instruments ULTIboard layout
49 * The `verilog' backend to `gnetlist' now supports concatenated net
50 naming like "{a,b,c[3:0]}".
52 * `gsch2pcb' no longer supports the `m4_command' parameter in project
55 * The `--m4-pcbdir' and `--m4-file' arguments to `gsch2pcb' now work
58 Notable changes in gEDA/gaf 1.7.1
59 =================================
61 * gEDA is now compatible with Guile 2.0.
63 * gEDA/gaf applications no longer complain when trying to load an rc
64 file twice, or when an rc file doesn't exist.
66 * `gschem' allows objects to be moved by dragging without having to
69 * `gschem' now supports keybindings with more than one modifier key,
70 and "Deselect" is bound to <Control Shift A> by default.
72 * `gnetlist' correctly handles multiple renames of the same net. This
73 resolves some long-standing bugs with multipage schematics.
75 * The `spice-sdb' backend for `gnetlist' now has built-in support for
76 `SUBCKT_NMOS' and `SUBCKT_PMOS' devices.
78 * A new `makedepend' backend has been added to `gnetlist'. It
79 generates Makefile code for SPICE simulation dependencies.
81 * Visibility of embedded component attributes are now preserved by
84 * `gsch2pcb' correctly handles footprint names with hyphens (`-').
86 * `gsch2pcb' project files support quoting and escaping in
89 * Considerable enhancements to Unicode support when printing
90 schematics or exporting PostScript.
92 Notable changes in gEDA/gaf 1.7.0
93 =================================
95 * All gEDA/gaf applications now handle configuration files much more
96 strictly, and provide much more useful feedback when an error
99 * Several changes to `gschem' command-line options:
101 - The `-t' option is no longer supported.
103 - Several command-line options now support a long-form alternative.
105 - The `-s' option can now be used to run multiple Scheme scripts
106 during `gschem' startup.

109 during `gschem' startup.
111 - A new `-L' option is available, which adds a directory to the
114 - A new `-V' or `--version' option is available, which displays
117 * `gschem' now provides a "Select All" function, which is bound to
118 <Control a> by default, along with a corresponding "Deselect"
121 * In the `gschem' "Add component" dialog, filtering the component
122 library will expand matching libraries. If the filter is cancelled,
123 all libraries are collapsed. Components can now be selected by
124 double-clicking on them in the component list.
126 * The `gschem' "Edit Text Properties" dialog now has an easier to use
129 * Printed text size now better matches on-screen text size in
132 * Special characters, including commas, are now escaped or quoted
133 appropriately in `gattrib' CSV output.
135 * Several changes to `gnetlist' command-line options:
137 - Four command-line options specific to the `spice-sdb' backend have
138 been removed. They can be replaced with `-O <option>' according
139 to the following table:
141 -e, --embedd -O embedd_mode
142 -I, --include -O include_mode
143 -n, --nomunge -O nomunge_mode
144 -s, --sort -O sort_mode
146 - The list of available backends is now obtained using a new
147 `--list-backends' option. `-g help' no longer outputs a list of
150 - A new `-L' option is available, which adds a directory to the
153 - A new `-V' or `--version' option is available, which displays
156 - When run with invalid command-line arguments, `gnetlist' now exits
157 with non-zero exit status.
159 * Several `gnetlist' backends have now been fixed so that it should no
160 longer be necessary to set an expanded Guile stack in gEDA's config
163 * The `spice-sdb' backend for `gnetlist' now supports probes
164 (`TESTPOINT' devices).
166 * The undocumented `mk_verilog_syms' program is no longer installed.
167 The symbols it creates are still installed to
168 `${prefix}/share/gEDA/sym/verilog'.
170 Notable changes in gEDA/gaf 1.6.2
171 =================================
173 * PNG export from `gschem' will now be cropped correctly.

213 * Cleanup of the slot handling code in libgeda.
215 * Fixes/updates to the MinGW port.
217 * Updated the shipped documentation from the online wiki.
219 Notable changes in gEDA/gaf 1.5.3/1.5.4
220 =======================================
222 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
223 it was withdrawn before it was widely distributed.
225 * Text rendering using native system fonts:
227 - The various programs in gEDA/gaf no longer uses its own built-in
230 - Native system fonts are used for rendering, giving support for a
231 wider range of symbols, and better looking schematics.
233 * Always use PostScript fonts in gschem's PostScript output. The
234 "output-text", "text-output" and "output-vector-threshold" config
235 functions have been removed.
237 * Image rendering in 'gschem' uses cairo instead of GDK.
239 * Numerous build system changes:
241 - gEDA/gaf is now distributed as a single source archive, called
242 gEDA-<version>.tar.gz.
244 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
246 - `intltool' is no longer required.
248 - Documentation is now installed to ${docdir} (usually
249 ${prefix}/share/doc/gEDA).

252 common attribute names.
254 * The multi-attribute edit dialog in `gschem' now shows unpromoted
257 * Menu items in `gschem' now have icons and properly aligned key
258 bindings. They also support accelerator keys.
260 * The `gschem2pcb' and `PCBboard' netlist backends have been removed.
261 It is recommended to use `gsch2pcb' instead.
263 * Check for and reject non-footprint PCB files in 'gsch2pcb'.
265 * Removed unimplemented "File->Open" feature in 'gattrib'.
267 * Added --disable-gattrib command line flag to ./configure to disable the
268 building of 'gattrib'. This is useful if you are building against
269 gtk+ 2.17.x which breaks 'gattrib'.
271 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
272 backend is only useful in certain circumstances.
274 * Assign shortcuts "vd" and "vl" for changing between color schemes
277 * Fix problem with attached net attribute not being honored in 'gnetlist'.
279 * Focus the "save" button in the close confirmation dialog in 'gattrib' and
282 * Accept empty attributes in the src file in 'tragesym'.
284 * Cleaned up the slot dialog box in 'gschem'.
286 * Changed the grip size rendering in 'gschem' to be reasonably sized when

299 - 2449060: Graphic state left inconsistent cancelling from net mode
300 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
301 and libgeda: Make o_complex_copy() actually copy.
302 - 2455061: Gnetlist output changed, and tests fail with recent GLib
303 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
304 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
305 or close parenthesis.
306 - 2823755: gnetlist: Fix DEBUG builds.

311 * Lots of code, infrastructure, and doxygen documentation cleanup and
314 Notable changes in gEDA/gaf 1.5.2
315 =================================

322 * Net junction cues in `gschem' are drawn smaller now.
324 * Copy and paste now works between different `gschem' instances (using
327 * Recent files are no longer opened in a new `gschem' window.
329 * Major, *backwards-incompatible* changes to color handling in
330 `libgeda' and `gschem'.
332 - All colors are specified using hexadecimal `#RRGGBB' or
335 - The print and display color maps are now separate.
337 - A new Scheme syntax is used to inspect and modify color maps.
339 - If you wish to use a light background in `gschem', add the line:
341 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
343 to your personal or project gschemrc file.
345 * Attributes of embedded objects are now shown in the right color.
347 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
348 properly supported by the netlister. The pin type can be modified
349 by selecting a pin, then right-clicking it and selecting `Edit pin
352 * All of the symbols were modified to use overbar markup tags ("like
353 \_this\_") instead of separate lines.
355 * Log files are now saved to $HOME/.gEDA/logs rather than being
356 dropped in the current directory.

366 buses must be selected by clicking on the drawn path itself.
368 - Filled boxes, circles, text, and components, may be selected by
369 clicking anywhere in the bounding box.
371 - The default mouse click distance required to select an element was
372 increased to 10 pixels.
374 - Double-clicking on a net segment selects all connected net
377 * The percentage step in or out while zooming the display in `gschem'
378 is now configurable with the `zoom-gain' gschemrc parameter. The
379 default value is 20%.
381 * The size of steps when panning with the mouse wheel or with a
382 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
383 gschemrc parameter. The default setting scrolls in steps of 1/8 of
386 * A number of improvements were made to the `gschem' component
389 - The dialog now shows a table of top-level attributes in the
392 - It is now possible to expand/collapse a library by clicking
395 * Changes to fill- and line-styles in `gschem' can now be undone.
397 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
398 can be accessed by selecting an arc and selecting Edit->Edit.
400 * It is now possible to rotate objects while placing them in `gschem'.
402 * Support for arbitrary filled and unfilled paths, using a subset of
403 the SVG path syntax. For more information, please see the file
404 format specification.
405 <http://geda.seul.org/wiki/geda:file_format_spec>
407 - `gschem' does not yet provide a GUI for creating or editing path
408 elements. However, it does support rendering them. They can also
411 - Some of the symbols in the component library were updated to use
414 * A Scheme evaluation prompt was added to `gschem'. It can be
415 accessed by typing `:'.
417 * Improved algorithm for drawing hatched fills both on screen and in
420 * Color selection dialogs and menus in `gschem' now show the actual
421 color as well as the description. Color names are now translatable.
423 * `gattrib' now prompts to save changes.
425 * All of the unimplemented menu items and pages in `gattrib' were
428 * The `always-promote-attributes' gafrc parameter now takes a list of
429 strings as an argument. The space-delimited string syntax is

447 * The `gxyrs' pick-and-place tool was added.
449 Notable changes in gEDA/gaf 1.5.0
450 =================================
452 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
453 automatically connect to valid end points (such as pins and other
454 nets). The `magnetic-net-mode' gschemrc parameter can be used to
455 enable/disable this feature.
457 * Rotating a component while moving it in `gschem' now rotates around
458 the current mouse location.
