10 Notable changes in gEDA/gaf 1.7.1
11 =================================
13 * `gschem' allows objects to be moved by dragging without having to
16 * `gnetlist' correctly handles multiple renames of the same net. This
17 resolves some long-standing bugs with multipage schematics.
19 * Visibility of embedded component attributes are now preserved by
22 * `gsch2pcb' correctly handles footprint names with hyphens (`-').
24 * `gsch2pcb' project files support quoting and escaping in
27 * Considerable enhancements to Unicode support when printing
28 schematics or exporting PostScript.
30 Notable changes in gEDA/gaf 1.7.0
31 =================================
33 * All gEDA/gaf applications now handle configuration files much more
34 strictly, and provide much more useful feedback when an error
37 * Several changes to `gschem' command-line options:
39 - The `-t' option is no longer supported.
41 - Several command-line options now support a long-form alternative.
43 - The `-s' option can now be used to run multiple Scheme scripts
44 during `gschem' startup.
46 - A new `-c' option is available, which runs a Scheme expression
47 during `gschem' startup.
49 - A new `-L' option is available, which adds a directory to the
52 - A new `-V' or `--version' option is available, which displays
55 * `gschem' now provides a "Select All" function, which is bound to
56 <Control a> by default, along with a corresponding "Deselect"
59 * In the `gschem' "Add component" dialog, filtering the component
60 library will expand matching libraries. If the filter is cancelled,
61 all libraries are collapsed. Components can now be selected by
62 double-clicking on them in the component list.
64 * The `gschem' "Edit Text Properties" dialog now has an easier to use
67 * Printed text size now better matches on-screen text size in
70 * Special characters, including commas, are now escaped or quoted
71 appropriately in `gattrib' CSV output.
73 * Several changes to `gnetlist' command-line options:
75 - Four command-line options specific to the `spice-sdb' backend have
76 been removed. They can be replaced with `-O <option>' according
77 to the following table:
79 -e, --embedd -O embedd_mode
80 -I, --include -O include_mode
81 -n, --nomunge -O nomunge_mode
82 -s, --sort -O sort_mode
84 - The list of available backends is now obtained using a new
85 `--list-backends' option. `-g help' no longer outputs a list of
88 - A new `-L' option is available, which adds a directory to the
91 - A new `-V' or `--version' option is available, which displays
94 - When run with invalid command-line arguments, `gnetlist' now exits
95 with non-zero exit status.
97 * Several `gnetlist' backends have now been fixed so that it should no
98 longer be necessary to set an expanded Guile stack in gEDA's config
101 * The `spice-sdb' backend for `gnetlist' now supports probes
102 (`TESTPOINT' devices).
104 * The undocumented `mk_verilog_syms' program is no longer installed.
105 The symbols it creates are still installed to
106 `${prefix}/share/gEDA/sym/verilog'.

143 Notable changes in gEDA/gaf 1.6.0
144 =================================
146 * Fixed the GtkItemEntry code inside of gattrib code so that it builds
149 * In gschem, rubberband pin to pin connections by adding nets.
151 * Cleanup of the slot handling code in libgeda.
153 * Fixes/updates to the MinGW port.
155 * Updated the shipped documentation from the online wiki.
157 Notable changes in gEDA/gaf 1.5.3/1.5.4
158 =======================================
160 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
161 it was withdrawn before it was widely distributed.
163 * Text rendering using native system fonts:
165 - The various programs in gEDA/gaf no longer uses its own built-in
168 - Native system fonts are used for rendering, giving support for a
169 wider range of symbols, and better looking schematics.
171 * Always use PostScript fonts in gschem's PostScript output. The
172 "output-text", "text-output" and "output-vector-threshold" config
173 functions have been removed.
175 * Image rendering in 'gschem' uses cairo instead of GDK.
177 * Numerous build system changes:
179 - gEDA/gaf is now distributed as a single source archive, called
180 gEDA-<version>.tar.gz.
182 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
184 - `intltool' is no longer required.
186 - Documentation is now installed to ${docdir} (usually
187 ${prefix}/share/doc/gEDA).

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

237 - 2449060: Graphic state left inconsistent cancelling from net mode
238 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
239 and libgeda: Make o_complex_copy() actually copy.
240 - 2455061: Gnetlist output changed, and tests fail with recent GLib
241 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
242 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
243 or close parenthesis.
244 - 2823755: gnetlist: Fix DEBUG builds.
245 - 2836109: build-sys: Add check for groff html driver.
247 * Spanish translation were updated.
249 * Lots of code, infrastructure, and doxygen documentation cleanup and
252 Notable changes in gEDA/gaf 1.5.2
253 =================================
255 * `gschem' now uses Cairo for all rendering. This allows for
256 everything to be rendered anti-aliased.
258 * `gschem' now uses a mesh grid instead of dots by default.
260 * Net junction cues in `gschem' are drawn smaller now.
262 * Copy and paste now works between different `gschem' instances (using
265 * Recent files are no longer opened in a new `gschem' window.
267 * Major, *backwards-incompatible* changes to color handling in
268 `libgeda' and `gschem'.
270 - All colors are specified using hexadecimal `#RRGGBB' or
273 - The print and display color maps are now separate.
275 - A new Scheme syntax is used to inspect and modify color maps.
277 - If you wish to use a light background in `gschem', add the line:
279 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
281 to your personal or project gschemrc file.
283 * Attributes of embedded objects are now shown in the right color.
285 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
286 properly supported by the netlister. The pin type can be modified
287 by selecting a pin, then right-clicking it and selecting `Edit pin
290 * All of the symbols were modified to use overbar markup tags ("like
291 \_this\_") instead of separate lines.
293 * Log files are now saved to $HOME/.gEDA/logs rather than being
294 dropped in the current directory.
296 Notable changes in gEDA/gaf 1.5.1
297 =================================
299 * GTK+ version 2.8.x or later is now required.

304 buses must be selected by clicking on the drawn path itself.
306 - Filled boxes, circles, text, and components, may be selected by
307 clicking anywhere in the bounding box.
309 - The default mouse click distance required to select an element was
310 increased to 10 pixels.
312 - Double-clicking on a net segment selects all connected net
315 * The percentage step in or out while zooming the display in `gschem'
316 is now configurable with the `zoom-gain' gschemrc parameter. The
317 default value is 20%.
319 * The size of steps when panning with the mouse wheel or with a
320 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
321 gschemrc parameter. The default setting scrolls in steps of 1/8 of
324 * A number of improvements were made to the `gschem' component
327 - The dialog now shows a table of top-level attributes in the
330 - It is now possible to expand/collapse a library by clicking
333 * Changes to fill- and line-styles in `gschem' can now be undone.
335 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
336 can be accessed by selecting an arc and selecting Edit->Edit.
338 * It is now possible to rotate objects while placing them in `gschem'.
340 * Support for arbitrary filled and unfilled paths, using a subset of
341 the SVG path syntax. For more information, please see the file
342 format specification.
343 <http://geda.seul.org/wiki/geda:file_format_spec>
345 - `gschem' does not yet provide a GUI for creating or editing path
346 elements. However, it does support rendering them. They can also
349 - Some of the symbols in the component library were updated to use
352 * A Scheme evaluation prompt was added to `gschem'. It can be
353 accessed by typing `:'.
355 * Improved algorithm for drawing hatched fills both on screen and in
358 * Color selection dialogs and menus in `gschem' now show the actual
359 color as well as the description. Color names are now translatable.
361 * `gattrib' now prompts to save changes.
363 * All of the unimplemented menu items and pages in `gattrib' were
366 * The `always-promote-attributes' gafrc parameter now takes a list of
367 strings as an argument. The space-delimited string syntax is
370 * Some optimisations were made to the `gnetlist' connection traversal
371 algorithm to speed up netlisting large designs.
373 * A new netlist backend was added to support Liquid PCB.
374 <http://www.liquidpcb.org/>
376 * The `bom2' netlist backend now generates a `qty' column.
378 * Several improvements and fixes were made to the `systemc' backend.
380 * The `--gnetlist-arg' option to gsch2pcb can now be used to pass
381 extra `gnetlist' arguments.

385 * The `gxyrs' pick-and-place tool was added.
387 Notable changes in gEDA/gaf 1.5.0
388 =================================
390 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
391 automatically connect to valid end points (such as pins and other
392 nets). The `magnetic-net-mode' gschemrc parameter can be used to
393 enable/disable this feature.
395 * Rotating a component while moving it in `gschem' now rotates around
396 the current mouse location.
398 * The `verilog' and `vhdl' backends now work again.
