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 1.7.1
11 =================================
13 * gEDA is now compatible with Guile 2.0.
15 * gEDA/gaf applications no longer complain when trying to load an rc
16 file twice, or when an rc file doesn't exist.
18 * `gschem' allows objects to be moved by dragging without having to
21 * `gschem' now supports keybindings with more than one modifier key,
22 and "Deselect" is bound to <Control Shift A> by default.
24 * `gnetlist' correctly handles multiple renames of the same net. This
25 resolves some long-standing bugs with multipage schematics.
27 * The `spice-sdb' backend for `gnetlist' now has built-in support for
28 `SUBCKT_NMOS' and `SUBCKT_PMOS' devices.
30 * Visibility of embedded component attributes are now preserved by
33 * `gsch2pcb' correctly handles footprint names with hyphens (`-').
35 * `gsch2pcb' project files support quoting and escaping in
38 * Considerable enhancements to Unicode support when printing
39 schematics or exporting PostScript.
41 Notable changes in gEDA/gaf 1.7.0
42 =================================
44 * All gEDA/gaf applications now handle configuration files much more
45 strictly, and provide much more useful feedback when an error
48 * Several changes to `gschem' command-line options:
50 - The `-t' option is no longer supported.
52 - Several command-line options now support a long-form alternative.
54 - The `-s' option can now be used to run multiple Scheme scripts
55 during `gschem' startup.
57 - A new `-c' option is available, which runs a Scheme expression
58 during `gschem' startup.
60 - A new `-L' option is available, which adds a directory to the
63 - A new `-V' or `--version' option is available, which displays
66 * `gschem' now provides a "Select All" function, which is bound to
67 <Control a> by default, along with a corresponding "Deselect"
70 * In the `gschem' "Add component" dialog, filtering the component
71 library will expand matching libraries. If the filter is cancelled,
72 all libraries are collapsed. Components can now be selected by
73 double-clicking on them in the component list.
75 * The `gschem' "Edit Text Properties" dialog now has an easier to use
78 * Printed text size now better matches on-screen text size in
81 * Special characters, including commas, are now escaped or quoted
82 appropriately in `gattrib' CSV output.
84 * Several changes to `gnetlist' command-line options:
86 - Four command-line options specific to the `spice-sdb' backend have
87 been removed. They can be replaced with `-O <option>' according
88 to the following table:
90 -e, --embedd -O embedd_mode
91 -I, --include -O include_mode
92 -n, --nomunge -O nomunge_mode
93 -s, --sort -O sort_mode
95 - The list of available backends is now obtained using a new
96 `--list-backends' option. `-g help' no longer outputs a list of
99 - A new `-L' option is available, which adds a directory to the
102 - A new `-V' or `--version' option is available, which displays
105 - When run with invalid command-line arguments, `gnetlist' now exits
106 with non-zero exit status.
108 * Several `gnetlist' backends have now been fixed so that it should no
109 longer be necessary to set an expanded Guile stack in gEDA's config
112 * The `spice-sdb' backend for `gnetlist' now supports probes
113 (`TESTPOINT' devices).
115 * The undocumented `mk_verilog_syms' program is no longer installed.
116 The symbols it creates are still installed to
117 `${prefix}/share/gEDA/sym/verilog'.
119 Notable changes in gEDA/gaf 1.6.2
120 =================================
122 * PNG export from `gschem' will now be cropped correctly.
124 * The `partlist' backends for `gnetlist' now handle hierarchical
127 * On Windows, `gschem' and `gattrib' will no longer launch with a

154 Notable changes in gEDA/gaf 1.6.0
155 =================================
157 * Fixed the GtkItemEntry code inside of gattrib code so that it builds
160 * In gschem, rubberband pin to pin connections by adding nets.
162 * Cleanup of the slot handling code in libgeda.
164 * Fixes/updates to the MinGW port.
166 * Updated the shipped documentation from the online wiki.
168 Notable changes in gEDA/gaf 1.5.3/1.5.4
169 =======================================
171 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
172 it was withdrawn before it was widely distributed.
174 * Text rendering using native system fonts:
176 - The various programs in gEDA/gaf no longer uses its own built-in
179 - Native system fonts are used for rendering, giving support for a
180 wider range of symbols, and better looking schematics.
182 * Always use PostScript fonts in gschem's PostScript output. The
183 "output-text", "text-output" and "output-vector-threshold" config
184 functions have been removed.
186 * Image rendering in 'gschem' uses cairo instead of GDK.
188 * Numerous build system changes:
190 - gEDA/gaf is now distributed as a single source archive, called
191 gEDA-<version>.tar.gz.
193 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
195 - `intltool' is no longer required.
197 - Documentation is now installed to ${docdir} (usually
198 ${prefix}/share/doc/gEDA).

201 common attribute names.
203 * The multi-attribute edit dialog in `gschem' now shows unpromoted
206 * Menu items in `gschem' now have icons and properly aligned key
207 bindings. They also support accelerator keys.
209 * The `gschem2pcb' and `PCBboard' netlist backends have been removed.
210 It is recommended to use `gsch2pcb' instead.
212 * Check for and reject non-footprint PCB files in 'gsch2pcb'.
214 * Removed unimplemented "File->Open" feature in 'gattrib'.
216 * Added --disable-gattrib command line flag to ./configure to disable the
217 building of 'gattrib'. This is useful if you are building against
218 gtk+ 2.17.x which breaks 'gattrib'.
220 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
221 backend is only useful in certain circumstances.
223 * Assign shortcuts "vd" and "vl" for changing between color schemes
226 * Fix problem with attached net attribute not being honored in 'gnetlist'.
228 * Focus the "save" button in the close confirmation dialog in 'gattrib' and
231 * Accept empty attributes in the src file in 'tragesym'.
233 * Cleaned up the slot dialog box in 'gschem'.
235 * Changed the grip size rendering in 'gschem' to be reasonably sized when
238 * Introduction of a new attribute searching API in 'libgeda' and 'gschem'.
240 * Improvements and cleanup to the 'gnetlist' and 'gsymcheck' test suites.
242 * Fixed the following bugs:

247 - 2430369: gschem: Deselect invisible attribs with their parent object.
248 - 2449060: Graphic state left inconsistent cancelling from net mode
249 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
250 and libgeda: Make o_complex_copy() actually copy.
251 - 2455061: Gnetlist output changed, and tests fail with recent GLib
252 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
253 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
254 or close parenthesis.
255 - 2823755: gnetlist: Fix DEBUG builds.
256 - 2836109: build-sys: Add check for groff html driver.
258 * Spanish translation were updated.
260 * Lots of code, infrastructure, and doxygen documentation cleanup and
263 Notable changes in gEDA/gaf 1.5.2
264 =================================

267 everything to be rendered anti-aliased.
269 * `gschem' now uses a mesh grid instead of dots by default.
271 * Net junction cues in `gschem' are drawn smaller now.
273 * Copy and paste now works between different `gschem' instances (using
276 * Recent files are no longer opened in a new `gschem' window.
278 * Major, *backwards-incompatible* changes to color handling in
279 `libgeda' and `gschem'.
281 - All colors are specified using hexadecimal `#RRGGBB' or
284 - The print and display color maps are now separate.
286 - A new Scheme syntax is used to inspect and modify color maps.
288 - If you wish to use a light background in `gschem', add the line:
290 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
292 to your personal or project gschemrc file.
294 * Attributes of embedded objects are now shown in the right color.
296 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
297 properly supported by the netlister. The pin type can be modified
298 by selecting a pin, then right-clicking it and selecting `Edit pin
301 * All of the symbols were modified to use overbar markup tags ("like
302 \_this\_") instead of separate lines.
304 * Log files are now saved to $HOME/.gEDA/logs rather than being
305 dropped in the current directory.
307 Notable changes in gEDA/gaf 1.5.1
308 =================================
310 * GTK+ version 2.8.x or later is now required.

314 - Lines, unfilled boxes, unfilled circles, arcs, pins, nets, and
315 buses must be selected by clicking on the drawn path itself.
317 - Filled boxes, circles, text, and components, may be selected by
318 clicking anywhere in the bounding box.
320 - The default mouse click distance required to select an element was
321 increased to 10 pixels.
323 - Double-clicking on a net segment selects all connected net
326 * The percentage step in or out while zooming the display in `gschem'
327 is now configurable with the `zoom-gain' gschemrc parameter. The
328 default value is 20%.
330 * The size of steps when panning with the mouse wheel or with a
331 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
332 gschemrc parameter. The default setting scrolls in steps of 1/8 of
335 * A number of improvements were made to the `gschem' component
338 - The dialog now shows a table of top-level attributes in the
341 - It is now possible to expand/collapse a library by clicking
344 * Changes to fill- and line-styles in `gschem' can now be undone.
346 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
347 can be accessed by selecting an arc and selecting Edit->Edit.
349 * It is now possible to rotate objects while placing them in `gschem'.
351 * Support for arbitrary filled and unfilled paths, using a subset of
352 the SVG path syntax. For more information, please see the file
353 format specification.
354 <http://geda.seul.org/wiki/geda:file_format_spec>
356 - `gschem' does not yet provide a GUI for creating or editing path
357 elements. However, it does support rendering them. They can also
360 - Some of the symbols in the component library were updated to use
363 * A Scheme evaluation prompt was added to `gschem'. It can be
364 accessed by typing `:'.
366 * Improved algorithm for drawing hatched fills both on screen and in
369 * Color selection dialogs and menus in `gschem' now show the actual
370 color as well as the description. Color names are now translatable.
372 * `gattrib' now prompts to save changes.
374 * All of the unimplemented menu items and pages in `gattrib' were
377 * The `always-promote-attributes' gafrc parameter now takes a list of
378 strings as an argument. The space-delimited string syntax is
381 * Some optimisations were made to the `gnetlist' connection traversal
382 algorithm to speed up netlisting large designs.
384 * A new netlist backend was added to support Liquid PCB.
385 <http://www.liquidpcb.org/>
387 * The `bom2' netlist backend now generates a `qty' column.
389 * Several improvements and fixes were made to the `systemc' backend.
391 * The `--gnetlist-arg' option to gsch2pcb can now be used to pass
392 extra `gnetlist' arguments.
394 * `gsch2pcb' now emits files with the latest `pcb' file format.
396 * The `gxyrs' pick-and-place tool was added.
398 Notable changes in gEDA/gaf 1.5.0
399 =================================
401 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
402 automatically connect to valid end points (such as pins and other
403 nets). The `magnetic-net-mode' gschemrc parameter can be used to
404 enable/disable this feature.
406 * Rotating a component while moving it in `gschem' now rotates around
407 the current mouse location.
409 * The `verilog' and `vhdl' backends now work again.
