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 1.6.0
11 =================================
13 * Numerous build system changes.
15 - gEDA/gaf is now distributed as a single source archive, called
16 gEDA-<version>.tar.gz.
18 - GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
20 - `intltool' is no longer required.
22 - Documentation is now installed to ${docdir} (usually
23 ${prefix}/share/doc/gEDA).
25 * The attribute edit dialog in `gschem' now has completion of most
26 common attribute names.
28 * The multi-attribute edit dialog in `gschem' now shows unpromoted
31 * Menu items in `gschem' now have icons and properly aligned key
32 bindings. They also support accelerator keys.
34 * The `gschem2pcb' and `PCBboard' netlist backends have been removed.
35 It is recommended to use `gsch2pcb' instead.
37 Notable changes in gEDA/gaf 1.5.2
38 =================================
40 * `gschem' now uses Cairo for all rendering. This allows for
41 everything to be rendered anti-aliased.
43 * `gschem' now uses a mesh grid instead of dots by default.
45 * Net junction cues in `gschem' are drawn smaller now.
47 * Copy and paste now works between different `gschem' instances (using
50 * Recent files are no longer opened in a new `gschem' window.
52 * Major, *backwards-incompatible* changes to color handling in
53 `libgeda' and `gschem'.
55 - All colors are specified using hexadecimal `#RRGGBB' or
58 - The print and display color maps are now separate.
60 - A new Scheme syntax is used to inspect and modify color maps.
62 - If you wish to use a light background in `gschem', add the line:
64 (load (build-path geda-rc-path "gschem-colormap-lightbg"))
66 to your personal or project gschemrc file.
68 * Attributes of embedded objects are now shown in the right color.
70 * Bus pins are now supported by `gschem' and `libgeda', but are *not*
71 properly supported by the netlister. The pin type can be modified
72 by selecting a pin, then right-clicking it and selecting `Edit pin
75 * All of the symbols were modified to use overbar markup tags ("like
76 \_this\_") instead of separate lines.
78 * Log files are now saved to $HOME/.gEDA/logs rather than being
79 dropped in the current directory.
81 Notable changes in gEDA/gaf 1.5.1
82 =================================
84 * GTK+ version 2.8.x or later is now required.
86 * The selection behaviour in `gschem' was changed.
88 - Lines, unfilled boxes, unfilled circles, arcs, pins, nets, and
89 buses must be selected by clicking on the drawn path itself.
91 - Filled boxes, circles, text, and components, may be selected by
92 clicking anywhere in the bounding box.
94 - The default mouse click distance required to select an element was
95 increased to 10 pixels.
97 - Double-clicking on a net segment selects all connected net
100 * The percentage step in or out while zooming the display in `gschem'
101 is now configurable with the `zoom-gain' gschemrc parameter. The
102 default value is 20%.
104 * The size of steps when panning with the mouse wheel or with a
105 trackpad in `gschem' is now adjustable with the `scrollpan-steps'
106 gschemrc parameter. The default setting scrolls in steps of 1/8 of
109 * A number of improvements were made to the `gschem' component
112 - The dialog now shows a table of top-level attributes in the
115 - It is now possible to expand/collapse a library by clicking
118 * Changes to fill- and line-styles in `gschem' can now be undone.
120 * Arcs can now be adjusted in `gschem' using an arc angle dialog. It
121 can be accessed by selecting an arc and selecting Edit->Edit.
123 * It is now possible to rotate objects while placing them in `gschem'.
125 * Support for arbitrary filled and unfilled paths, using a subset of
126 the SVG path syntax. For more information, please see the file
127 format specification.
128 <http://geda.seul.org/wiki/geda:file_format_spec>
130 - `gschem' does not yet provide a GUI for creating or editing path
131 elements. However, it does support rendering them. They can also
134 - Some of the symbols in the component library were updated to use
137 * A Scheme evaluation prompt was added to `gschem'. It can be
138 accessed by typing `:'.
140 * Improved algorithm for drawing hatched fills both on screen and in
143 * Color selection dialogs and menus in `gschem' now show the actual
144 color as well as the description. Color names are now translatable.
146 * `gattrib' now prompts to save changes.
148 * All of the unimplemented menu items and pages in `gattrib' were
151 * The `always-promote-attributes' gafrc parameter now takes a list of
152 strings as an argument. The space-delimited string syntax is
155 * Some optimisations were made to the `gnetlist' connection traversal
156 algorithm to speed up netlisting large designs.
158 * A new netlist backend was added to support Liquid PCB.
159 <http://www.liquidpcb.org/>
161 * The `bom2' netlist backend now generates a `qty' column.
163 * Several improvements and fixes were made to the `systemc' backend.
165 * The `--gnetlist-arg' option to gsch2pcb can now be used to pass
166 extra `gnetlist' arguments.
168 * `gsch2pcb' now emits files with the latest `pcb' file format.
170 * The `gxyrs' pick-and-place tool was added.
172 Notable changes in gEDA/gaf 1.5.0
173 =================================
175 * Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
176 automatically connect to valid end points (such as pins and other
177 nets). The `magnetic-net-mode' gschemrc parameter can be used to
178 enable/disable this feature.
180 * Rotating a component while moving it in `gschem' now rotates around
181 the current mouse location.
183 * The `verilog' and `vhdl' backends now work again.
185 * Embedded components can now be mirrored.
187 * The `pads' netlist backend now uses CRLF line endings.
192 Release notes for older versions of gEDA/gaf are available on the gEDA
193 website. <http://www.gpleda.org/news/index.html>
