8 more information, please consult the `ChangeLog' file.
10 Notable changes in gEDA/gaf 1.7.2
11 =================================
13 * A greatly expanded Scheme API has been added to gEDA/gaf for use by
14 extension authors. See the `geda-scheme' Info manual for more
15 details. Existing extensions may need to be modified to load the
16 `(geda deprecated)' or `(gschem deprecated)' modules.
18 Notable changes in gEDA/gaf 1.7.1
19 =================================
21 * gEDA is now compatible with Guile 2.0.
23 * gEDA/gaf applications no longer complain when trying to load an rc
24 file twice, or when an rc file doesn't exist.
26 * `gschem' allows objects to be moved by dragging without having to
29 * `gschem' now supports keybindings with more than one modifier key,
30 and "Deselect" is bound to <Control Shift A> by default.
32 * `gnetlist' correctly handles multiple renames of the same net. This
33 resolves some long-standing bugs with multipage schematics.
35 * The `spice-sdb' backend for `gnetlist' now has built-in support for
36 `SUBCKT_NMOS' and `SUBCKT_PMOS' devices.
38 * A new `makedepend' backend has been added to `gnetlist'. It
39 generates Makefile code for SPICE simulation dependencies.
41 * Visibility of embedded component attributes are now preserved by
44 * `gsch2pcb' correctly handles footprint names with hyphens (`-').
46 * `gsch2pcb' project files support quoting and escaping in
49 * Considerable enhancements to Unicode support when printing
50 schematics or exporting PostScript.
52 Notable changes in gEDA/gaf 1.7.0
53 =================================
55 * All gEDA/gaf applications now handle configuration files much more
56 strictly, and provide much more useful feedback when an error
59 * Several changes to `gschem' command-line options:
61 - The `-t' option is no longer supported.
63 - Several command-line options now support a long-form alternative.
65 - The `-s' option can now be used to run multiple Scheme scripts
66 during `gschem' startup.
68 - A new `-c' option is available, which runs a Scheme expression
69 during `gschem' startup.
71 - A new `-L' option is available, which adds a directory to the
74 - A new `-V' or `--version' option is available, which displays
77 * `gschem' now provides a "Select All" function, which is bound to
78 <Control a> by default, along with a corresponding "Deselect"
81 * In the `gschem' "Add component" dialog, filtering the component
82 library will expand matching libraries. If the filter is cancelled,
83 all libraries are collapsed. Components can now be selected by
84 double-clicking on them in the component list.
86 * The `gschem' "Edit Text Properties" dialog now has an easier to use
89 * Printed text size now better matches on-screen text size in
92 * Special characters, including commas, are now escaped or quoted
93 appropriately in `gattrib' CSV output.
95 * Several changes to `gnetlist' command-line options:
97 - Four command-line options specific to the `spice-sdb' backend have
98 been removed. They can be replaced with `-O <option>' according
99 to the following table:
101 -e, --embedd -O embedd_mode
102 -I, --include -O include_mode
103 -n, --nomunge -O nomunge_mode
104 -s, --sort -O sort_mode
106 - The list of available backends is now obtained using a new
107 `--list-backends' option. `-g help' no longer outputs a list of
110 - A new `-L' option is available, which adds a directory to the
113 - A new `-V' or `--version' option is available, which displays
116 - When run with invalid command-line arguments, `gnetlist' now exits
117 with non-zero exit status.
119 * Several `gnetlist' backends have now been fixed so that it should no
120 longer be necessary to set an expanded Guile stack in gEDA's config
123 * The `spice-sdb' backend for `gnetlist' now supports probes
124 (`TESTPOINT' devices).
126 * The undocumented `mk_verilog_syms' program is no longer installed.
127 The symbols it creates are still installed to
128 `${prefix}/share/gEDA/sym/verilog'.
130 Notable changes in gEDA/gaf 1.6.2
131 =================================
133 * PNG export from `gschem' will now be cropped correctly.
135 * The `partlist' backends for `gnetlist' now handle hierarchical
138 * On Windows, `gschem' and `gattrib' will no longer launch with a
139 command window visible.
141 * `gnetlist-arg' is no longer valid in `gsch2pcb' project files.
143 Several other bugs were fixed, including a major crash bug in
146 Notable changes in gEDA/gaf 1.6.1
147 =================================

162 - Cherry picked some other bug fixes from master that should be in
165 Notable changes in gEDA/gaf 1.6.0
166 =================================
168 * Fixed the GtkItemEntry code inside of gattrib code so that it builds
171 * In gschem, rubberband pin to pin connections by adding nets.
173 * Cleanup of the slot handling code in libgeda.
175 * Fixes/updates to the MinGW port.
177 * Updated the shipped documentation from the online wiki.
179 Notable changes in gEDA/gaf 1.5.3/1.5.4
180 =======================================
182 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
183 it was withdrawn before it was widely distributed.
185 * Text rendering using native system fonts:
187 - The various programs in gEDA/gaf no longer uses its own built-in
190 - Native system fonts are used for rendering, giving support for a
191 wider range of symbols, and better looking schematics.
193 * Always use PostScript fonts in gschem's PostScript output. The
194 "output-text", "text-output" and "output-vector-threshold" config
195 functions have been removed.
197 * Image rendering in 'gschem' uses cairo instead of GDK.
199 * Numerous build system changes:
201 - gEDA/gaf is now distributed as a single source archive, called
202 gEDA-<version>.tar.gz.
204 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
206 - `intltool' is no longer required.
208 - Documentation is now installed to ${docdir} (usually
209 ${prefix}/share/doc/gEDA).

212 common attribute names.
214 * The multi-attribute edit dialog in `gschem' now shows unpromoted
217 * Menu items in `gschem' now have icons and properly aligned key
218 bindings. They also support accelerator keys.
220 * The `gschem2pcb' and `PCBboard' netlist backends have been removed.
221 It is recommended to use `gsch2pcb' instead.
223 * Check for and reject non-footprint PCB files in 'gsch2pcb'.
225 * Removed unimplemented "File->Open" feature in 'gattrib'.
227 * Added --disable-gattrib command line flag to ./configure to disable the
228 building of 'gattrib'. This is useful if you are building against
229 gtk+ 2.17.x which breaks 'gattrib'.
231 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
232 backend is only useful in certain circumstances.
234 * Assign shortcuts "vd" and "vl" for changing between color schemes
237 * Fix problem with attached net attribute not being honored in 'gnetlist'.
239 * Focus the "save" button in the close confirmation dialog in 'gattrib' and
242 * Accept empty attributes in the src file in 'tragesym'.
244 * Cleaned up the slot dialog box in 'gschem'.

259 - 2449060: Graphic state left inconsistent cancelling from net mode
260 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
261 and libgeda: Make o_complex_copy() actually copy.
262 - 2455061: Gnetlist output changed, and tests fail with recent GLib
263 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
264 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
265 or close parenthesis.
266 - 2823755: gnetlist: Fix DEBUG builds.
267 - 2836109: build-sys: Add check for groff html driver.

271 * Lots of code, infrastructure, and doxygen documentation cleanup and
274 Notable changes in gEDA/gaf 1.5.2
275 =================================

282 * Net junction cues in `gschem' are drawn smaller now.
284 * Copy and paste now works between different `gschem' instances (using
287 * Recent files are no longer opened in a new `gschem' window.
289 * Major, *backwards-incompatible* changes to color handling in
290 `libgeda' and `gschem'.
292 - All colors are specified using hexadecimal `#RRGGBB' or
295 - The print and display color maps are now separate.
297 - A new Scheme syntax is used to inspect and modify color maps.
299 - If you wish to use a light background in `gschem', add the line:
301 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
303 to your personal or project gschemrc file.
305 * Attributes of embedded objects are now shown in the right color.
307 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
308 properly supported by the netlister. The pin type can be modified
309 by selecting a pin, then right-clicking it and selecting `Edit pin
312 * All of the symbols were modified to use overbar markup tags ("like
313 \_this\_") instead of separate lines.
315 * Log files are now saved to $HOME/.gEDA/logs rather than being
316 dropped in the current directory.

326 buses must be selected by clicking on the drawn path itself.
328 - Filled boxes, circles, text, and components, may be selected by
329 clicking anywhere in the bounding box.
331 - The default mouse click distance required to select an element was
332 increased to 10 pixels.
334 - Double-clicking on a net segment selects all connected net
337 * The percentage step in or out while zooming the display in `gschem'
338 is now configurable with the `zoom-gain' gschemrc parameter. The
339 default value is 20%.
341 * The size of steps when panning with the mouse wheel or with a
342 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
343 gschemrc parameter. The default setting scrolls in steps of 1/8 of
346 * A number of improvements were made to the `gschem' component
349 - The dialog now shows a table of top-level attributes in the
352 - It is now possible to expand/collapse a library by clicking
355 * Changes to fill- and line-styles in `gschem' can now be undone.
357 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
358 can be accessed by selecting an arc and selecting Edit->Edit.
360 * It is now possible to rotate objects while placing them in `gschem'.
362 * Support for arbitrary filled and unfilled paths, using a subset of
363 the SVG path syntax. For more information, please see the file
364 format specification.
365 <http://geda.seul.org/wiki/geda:file_format_spec>
367 - `gschem' does not yet provide a GUI for creating or editing path
368 elements. However, it does support rendering them. They can also
371 - Some of the symbols in the component library were updated to use
374 * A Scheme evaluation prompt was added to `gschem'. It can be
375 accessed by typing `:'.
377 * Improved algorithm for drawing hatched fills both on screen and in
380 * Color selection dialogs and menus in `gschem' now show the actual
381 color as well as the description. Color names are now translatable.
383 * `gattrib' now prompts to save changes.
385 * All of the unimplemented menu items and pages in `gattrib' were
388 * The `always-promote-attributes' gafrc parameter now takes a list of
389 strings as an argument. The space-delimited string syntax is

393 algorithm to speed up netlisting large designs.
395 * A new netlist backend was added to support Liquid PCB.
396 <http://www.liquidpcb.org/>
398 * The `bom2' netlist backend now generates a `qty' column.
400 * Several improvements and fixes were made to the `systemc' backend.
402 * The `--gnetlist-arg' option to gsch2pcb can now be used to pass
403 extra `gnetlist' arguments.

407 * The `gxyrs' pick-and-place tool was added.
409 Notable changes in gEDA/gaf 1.5.0
410 =================================
412 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
413 automatically connect to valid end points (such as pins and other
414 nets). The `magnetic-net-mode' gschemrc parameter can be used to
415 enable/disable this feature.
417 * Rotating a component while moving it in `gschem' now rotates around
418 the current mouse location.
