29 Notable changes in gEDA/gaf 1.6.0
30 =================================
32 * Fixed the GtkItemEntry code inside of gattrib code so that it builds
35 * In gschem, rubberband pin to pin connections by adding nets.
37 * Cleanup of the slot handling code in libgeda.
39 * Fixes/updates to the MinGW port.
41 * Updated the shipped documentation from the online wiki.
43 Notable changes in gEDA/gaf 1.5.3/1.5.4
44 =======================================
46 * NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
47 it was withdrawn before it was widely distributed.
49 * Text rendering using native system fonts:
51 - The various programs in gEDA/gaf no longer uses its own built-in
54 - Native system fonts are used for rendering, giving support for a
55 wider range of symbols, and better looking schematics.
57 * Always use PostScript fonts in gschem's PostScript output. The
58 "output-text", "text-output" and "output-vector-threshold" config
59 functions have been removed.
61 * Image rendering in 'gschem' uses cairo instead of GDK.
63 * Numerous build system changes:
65 - gEDA/gaf is now distributed as a single source archive, called
66 gEDA-<version>.tar.gz.
68 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
70 - `intltool' is no longer required.
72 - Documentation is now installed to ${docdir} (usually
73 ${prefix}/share/doc/gEDA).
75 * The attribute edit dialog in `gschem' now has completion of most
76 common attribute names.
78 * The multi-attribute edit dialog in `gschem' now shows unpromoted
81 * Menu items in `gschem' now have icons and properly aligned key
82 bindings. They also support accelerator keys.
84 * The `gschem2pcb' and `PCBboard' netlist backends have been removed.
85 It is recommended to use `gsch2pcb' instead.
87 * Check for and reject non-footprint PCB files in 'gsch2pcb'.
89 * Removed unimplemented "File->Open" feature in 'gattrib'.
91 * Added --disable-gattrib command line flag to ./configure to disable the
92 building of 'gattrib'. This is useful if you are building against
93 gtk+ 2.17.x which breaks 'gattrib'.
95 * 'gnetlist' does not recommend drc2 every time it runs. The drc2
96 backend is only useful in certain circumstances.
98 * Assign shortcuts "vd" and "vl" for changing between color schemes
101 * Fix problem with attached net attribute not being honored in 'gnetlist'.
103 * Focus the "save" button in the close confirmation dialog in 'gattrib' and
106 * Accept empty attributes in the src file in 'tragesym'.
108 * Cleaned up the slot dialog box in 'gschem'.
110 * Changed the grip size rendering in 'gschem' to be reasonably sized when
113 * Introduction of a new attribute searching API in 'libgeda' and 'gschem'.
115 * Improvements and cleanup to the 'gnetlist' and 'gsymcheck' test suites.
117 * Fixed the following bugs:
119 - 1758673: Combine source tarballs
120 - 2058707: gschem, gattrib: Dangerous button focus in "Save changes"
122 - 2430369: gschem: Deselect invisible attribs with their parent object.
123 - 2449060: Graphic state left inconsistent cancelling from net mode
124 - 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
125 and libgeda: Make o_complex_copy() actually copy.
126 - 2455061: Gnetlist output changed, and tests fail with recent GLib
127 - 2655088: autogen.sh: Make sure to exit if autopoint fails.
128 - 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
129 or close parenthesis.
130 - 2823755: gnetlist: Fix DEBUG builds.
131 - 2836109: build-sys: Add check for groff html driver.
133 * Spanish translation were updated.
135 * Lots of code, infrastructure, and doxygen documentation cleanup and
138 Notable changes in gEDA/gaf 1.5.2
139 =================================
141 * `gschem' now uses Cairo for all rendering. This allows for
142 everything to be rendered anti-aliased.
144 * `gschem' now uses a mesh grid instead of dots by default.
146 * Net junction cues in `gschem' are drawn smaller now.
148 * Copy and paste now works between different `gschem' instances (using
151 * Recent files are no longer opened in a new `gschem' window.
153 * Major, *backwards-incompatible* changes to color handling in
154 `libgeda' and `gschem'.
156 - All colors are specified using hexadecimal `#RRGGBB' or
159 - The print and display color maps are now separate.
161 - A new Scheme syntax is used to inspect and modify color maps.
163 - If you wish to use a light background in `gschem', add the line:
165 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
167 to your personal or project gschemrc file.
169 * Attributes of embedded objects are now shown in the right color.
171 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
172 properly supported by the netlister. The pin type can be modified
173 by selecting a pin, then right-clicking it and selecting `Edit pin
176 * All of the symbols were modified to use overbar markup tags ("like
177 \_this\_") instead of separate lines.
179 * Log files are now saved to $HOME/.gEDA/logs rather than being
180 dropped in the current directory.
182 Notable changes in gEDA/gaf 1.5.1
183 =================================
185 * GTK+ version 2.8.x or later is now required.
187 * The selection behaviour in `gschem' was changed.
189 - Lines, unfilled boxes, unfilled circles, arcs, pins, nets, and
190 buses must be selected by clicking on the drawn path itself.
192 - Filled boxes, circles, text, and components, may be selected by
193 clicking anywhere in the bounding box.
195 - The default mouse click distance required to select an element was
196 increased to 10 pixels.
198 - Double-clicking on a net segment selects all connected net
201 * The percentage step in or out while zooming the display in `gschem'
202 is now configurable with the `zoom-gain' gschemrc parameter. The
203 default value is 20%.
205 * The size of steps when panning with the mouse wheel or with a
206 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
207 gschemrc parameter. The default setting scrolls in steps of 1/8 of
210 * A number of improvements were made to the `gschem' component
213 - The dialog now shows a table of top-level attributes in the
216 - It is now possible to expand/collapse a library by clicking
219 * Changes to fill- and line-styles in `gschem' can now be undone.
221 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
222 can be accessed by selecting an arc and selecting Edit->Edit.
224 * It is now possible to rotate objects while placing them in `gschem'.
226 * Support for arbitrary filled and unfilled paths, using a subset of
227 the SVG path syntax. For more information, please see the file
228 format specification.
229 <http://geda.seul.org/wiki/geda:file_format_spec>
231 - `gschem' does not yet provide a GUI for creating or editing path
232 elements. However, it does support rendering them. They can also
235 - Some of the symbols in the component library were updated to use
238 * A Scheme evaluation prompt was added to `gschem'. It can be
239 accessed by typing `:'.
241 * Improved algorithm for drawing hatched fills both on screen and in
244 * Color selection dialogs and menus in `gschem' now show the actual
245 color as well as the description. Color names are now translatable.
247 * `gattrib' now prompts to save changes.
249 * All of the unimplemented menu items and pages in `gattrib' were
252 * The `always-promote-attributes' gafrc parameter now takes a list of
253 strings as an argument. The space-delimited string syntax is
256 * Some optimisations were made to the `gnetlist' connection traversal
257 algorithm to speed up netlisting large designs.
259 * A new netlist backend was added to support Liquid PCB.
260 <http://www.liquidpcb.org/>
262 * The `bom2' netlist backend now generates a `qty' column.
264 * Several improvements and fixes were made to the `systemc' backend.
266 * The `--gnetlist-arg' option to gsch2pcb can now be used to pass
267 extra `gnetlist' arguments.
269 * `gsch2pcb' now emits files with the latest `pcb' file format.
271 * The `gxyrs' pick-and-place tool was added.
273 Notable changes in gEDA/gaf 1.5.0
274 =================================
276 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
277 automatically connect to valid end points (such as pins and other
278 nets). The `magnetic-net-mode' gschemrc parameter can be used to
279 enable/disable this feature.
281 * Rotating a component while moving it in `gschem' now rotates around
282 the current mouse location.
284 * The `verilog' and `vhdl' backends now work again.
