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 `bom' and `bom2' backends to `gnetlist' now give error messages
38 if no attribute file can be found. The `-O attrib_file=FILE' and
39 `-O attribs=ATTRIB,ATTRIB...' options have also been added.
41 * A new `ewnet' backend has been added to `gnetlist'. This outputs
42 netlists for use with the National Instruments ULTIboard layout
45 * `gsch2pcb' no longer supports the `m4_command' parameter in project
48 Notable changes in gEDA/gaf 1.7.1
49 =================================
51 * gEDA is now compatible with Guile 2.0.
53 * gEDA/gaf applications no longer complain when trying to load an rc
54 file twice, or when an rc file doesn't exist.
56 * `gschem' allows objects to be moved by dragging without having to
59 * `gschem' now supports keybindings with more than one modifier key,
60 and "Deselect" is bound to <Control Shift A> by default.
62 * `gnetlist' correctly handles multiple renames of the same net. This
63 resolves some long-standing bugs with multipage schematics.
65 * The `spice-sdb' backend for `gnetlist' now has built-in support for
66 `SUBCKT_NMOS' and `SUBCKT_PMOS' devices.
68 * A new `makedepend' backend has been added to `gnetlist'. It
69 generates Makefile code for SPICE simulation dependencies.
71 * Visibility of embedded component attributes are now preserved by
74 * `gsch2pcb' correctly handles footprint names with hyphens (`-').
76 * `gsch2pcb' project files support quoting and escaping in
79 * Considerable enhancements to Unicode support when printing
80 schematics or exporting PostScript.
82 Notable changes in gEDA/gaf 1.7.0
83 =================================
85 * All gEDA/gaf applications now handle configuration files much more
86 strictly, and provide much more useful feedback when an error
89 * Several changes to `gschem' command-line options:
91 - The `-t' option is no longer supported.
93 - Several command-line options now support a long-form alternative.
95 - The `-s' option can now be used to run multiple Scheme scripts
96 during `gschem' startup.
98 - A new `-c' option is available, which runs a Scheme expression
99 during `gschem' startup.
101 - A new `-L' option is available, which adds a directory to the
104 - A new `-V' or `--version' option is available, which displays
107 * `gschem' now provides a "Select All" function, which is bound to
108 <Control a> by default, along with a corresponding "Deselect"
111 * In the `gschem' "Add component" dialog, filtering the component
112 library will expand matching libraries. If the filter is cancelled,
113 all libraries are collapsed. Components can now be selected by
114 double-clicking on them in the component list.
116 * The `gschem' "Edit Text Properties" dialog now has an easier to use
119 * Printed text size now better matches on-screen text size in
122 * Special characters, including commas, are now escaped or quoted
123 appropriately in `gattrib' CSV output.
125 * Several changes to `gnetlist' command-line options:
127 - Four command-line options specific to the `spice-sdb' backend have
128 been removed. They can be replaced with `-O <option>' according
129 to the following table:
131 -e, --embedd -O embedd_mode
132 -I, --include -O include_mode
133 -n, --nomunge -O nomunge_mode
134 -s, --sort -O sort_mode
136 - The list of available backends is now obtained using a new
137 `--list-backends' option. `-g help' no longer outputs a list of
140 - A new `-L' option is available, which adds a directory to the
143 - A new `-V' or `--version' option is available, which displays
146 - When run with invalid command-line arguments, `gnetlist' now exits
147 with non-zero exit status.
149 * Several `gnetlist' backends have now been fixed so that it should no
150 longer be necessary to set an expanded Guile stack in gEDA's config
153 * The `spice-sdb' backend for `gnetlist' now supports probes
154 (`TESTPOINT' devices).
156 * The undocumented `mk_verilog_syms' program is no longer installed.
157 The symbols it creates are still installed to
158 `${prefix}/share/gEDA/sym/verilog'.

209 Notable changes in gEDA/gaf 1.5.3/1.5.4
210 =======================================
212 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
213 it was withdrawn before it was widely distributed.
215 * Text rendering using native system fonts:
217 - The various programs in gEDA/gaf no longer uses its own built-in
220 - Native system fonts are used for rendering, giving support for a
221 wider range of symbols, and better looking schematics.
223 * Always use PostScript fonts in gschem's PostScript output. The
224 "output-text", "text-output" and "output-vector-threshold" config
225 functions have been removed.
227 * Image rendering in 'gschem' uses cairo instead of GDK.
229 * Numerous build system changes:
231 - gEDA/gaf is now distributed as a single source archive, called
232 gEDA-<version>.tar.gz.
234 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.

251 It is recommended to use `gsch2pcb' instead.
253 * Check for and reject non-footprint PCB files in 'gsch2pcb'.
255 * Removed unimplemented "File->Open" feature in 'gattrib'.
257 * Added --disable-gattrib command line flag to ./configure to disable the
258 building of 'gattrib'. This is useful if you are building against
259 gtk+ 2.17.x which breaks 'gattrib'.
261 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
262 backend is only useful in certain circumstances.
264 * Assign shortcuts "vd" and "vl" for changing between color schemes
267 * Fix problem with attached net attribute not being honored in 'gnetlist'.
269 * Focus the "save" button in the close confirmation dialog in 'gattrib' and
272 * Accept empty attributes in the src file in 'tragesym'.

289 - 2449060: Graphic state left inconsistent cancelling from net mode
290 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
291 and libgeda: Make o_complex_copy() actually copy.
292 - 2455061: Gnetlist output changed, and tests fail with recent GLib
293 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
294 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
295 or close parenthesis.
296 - 2823755: gnetlist: Fix DEBUG builds.

319 * Major, *backwards-incompatible* changes to color handling in
320 `libgeda' and `gschem'.
322 - All colors are specified using hexadecimal `#RRGGBB' or
325 - The print and display color maps are now separate.
327 - A new Scheme syntax is used to inspect and modify color maps.
329 - If you wish to use a light background in `gschem', add the line:
331 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
333 to your personal or project gschemrc file.
335 * Attributes of embedded objects are now shown in the right color.
337 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
338 properly supported by the netlister. The pin type can be modified
339 by selecting a pin, then right-clicking it and selecting `Edit pin
342 * All of the symbols were modified to use overbar markup tags ("like
343 \_this\_") instead of separate lines.
345 * Log files are now saved to $HOME/.gEDA/logs rather than being
346 dropped in the current directory.

356 buses must be selected by clicking on the drawn path itself.
358 - Filled boxes, circles, text, and components, may be selected by
359 clicking anywhere in the bounding box.
361 - The default mouse click distance required to select an element was
362 increased to 10 pixels.
364 - Double-clicking on a net segment selects all connected net
367 * The percentage step in or out while zooming the display in `gschem'
368 is now configurable with the `zoom-gain' gschemrc parameter. The
369 default value is 20%.
371 * The size of steps when panning with the mouse wheel or with a
372 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
373 gschemrc parameter. The default setting scrolls in steps of 1/8 of
376 * A number of improvements were made to the `gschem' component
379 - The dialog now shows a table of top-level attributes in the
382 - It is now possible to expand/collapse a library by clicking
385 * Changes to fill- and line-styles in `gschem' can now be undone.
387 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
388 can be accessed by selecting an arc and selecting Edit->Edit.
390 * It is now possible to rotate objects while placing them in `gschem'.
392 * Support for arbitrary filled and unfilled paths, using a subset of
393 the SVG path syntax. For more information, please see the file
394 format specification.
395 <http://geda.seul.org/wiki/geda:file_format_spec>
397 - `gschem' does not yet provide a GUI for creating or editing path
398 elements. However, it does support rendering them. They can also
401 - Some of the symbols in the component library were updated to use
404 * A Scheme evaluation prompt was added to `gschem'. It can be
405 accessed by typing `:'.
407 * Improved algorithm for drawing hatched fills both on screen and in
410 * Color selection dialogs and menus in `gschem' now show the actual
411 color as well as the description. Color names are now translatable.

442 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
443 automatically connect to valid end points (such as pins and other
444 nets). The `magnetic-net-mode' gschemrc parameter can be used to
445 enable/disable this feature.
447 * Rotating a component while moving it in `gschem' now rotates around
448 the current mouse location.
