------------------------------
New in 20090213
- Fix warnings related to GtkTooltips
- fix reading of ascii spice3 rawfiles containing blank lines, like those
generated by ngspice
- add patchfile and explanation sometimes needed when building g-wrap
- applied submitted patch that fixes some gcc return-type warnings, fixed
many additional gcc warnings.
New in 20090124
- minor fixes adaptating for stable guile-gnome-platform-2.16.1
- seems to be stable now
New in 20080206
- Another alpha release using guile-gnome-platform, for wider testing
- Fixed "zoom dialog" for guile-gnome-platform
- Still having some occasional crashes, apparently due to memory corruption
that I haven't yet tracked down or pinned on guile-gnome-platform or anything else.
New in 20070514
a "gwave2" version that uses Gtk+-2.0 by way of guile-gnome-platform.
Feature-wise, about the same as the previous release.
I think I've fixed most of the crashes. Known defects:
Several dialogs that should have defaults don't.
The change-waveform-color menu doesn't show the colors, just numbers.

Release Notes for PCB snapshot 20100929
========================================================================
This release represents over 240 commits and as such this summary
clearly is not complete. See the ChangeLog file for the complete list
of changes.
Features
--------
- PCB can directly import (forward annotate) schematics while running.
- Many places where measurements are entered now accept units, like
"5mm", and "cm" and "in" are allowed too.
- Free Rotate Buffer added to menu
- Polygon Hole tool.
- F12 invokes the Lock tool.
- Russian translation added.
- DBUS is enabled by default when possible.
- Command-line exporters can run action scripts too.
- GTK tool tips on elements, pins, and nets.
- Command-line actions in GUIs do not require (,,) syntax.
- PCB can import footprints both in subdirectories and the named directories.
- New GCode exporter.
- Footprint files use ".fp" as the suffix; this is automatically
searched for if needed.
- GTK dialogs do not show at startup unless requested.
- Stackup can be specified on the command line for command-line exporting.
- Reference card updated.
- The snap-point in pads is the center.
- The 's' key toggles polygons to clear/notclear all pads and pins
Bug Fixes
---------
- Various PNG export fixes.
- lesstif's magic toggle-layers-on-flip fixed.
- Arc bounding box math fixed.
- Fixed: sometimes, disabling silk also disabled the solder layer.
- "pcb --help" prints all options again
- Add mnemonic for "close without saving"
- Don't select silk on the back side when it's invisible.
- Various polygon rendering bugs fixed.
- PNG drill bloat export fixed.
- Attempts to change polygon clearance *on* polygons results in a hint.
- PNG doesn't segfault if not all graphic formats are supported.
- Various toporouter fixes and improvements
- HID_Mixed is supported in attribute dialogs
- Flipped rectangles in PS exports are drawn correctly.
- Optimizer removes micro-traces under pads.
- Vias, pins, and pads are now drawn under the mask instead of over.
- Windows supported better.
Other
-----
- Sources converted to C99
- Doc extraction gives more control over categories.
- Thermal documentation updated.
- Actions can see the context they were invoked in
Notable changes in gEDA/gaf 1.6.2
=================================
* PNG export from `gschem' will now be cropped correctly.
* The `partlist' backends for `gnetlist' now handle hierarchical
refdes correctly.
* On Windows, `gschem' and `gattrib' will no longer launch with a
command window visible.
* `gnetlist-arg' is no longer valid in `gsch2pcb' project files.
Several other bugs were fixed, including a major crash bug in
gnetlist.

-bugfixes
pkgsrc change: clean up DESTDIR support
alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi
done
done
Based on PR#43410 by Wen Heping.
* add math to CATEGORIES.
* set LICENSE=gnu-lgpl-v2.1.
* add PyPi to MASTER_SITES.
* fixes test target.
* simplify PKGNAME.
Major changes from 2.0.1 are:
* A SimPy debugger which allows users to interactively step through their
simulation models. Not just for debugging, but also great for learning and
teaching SimPy!
* A new document, describing API and tools for gaining insight into and
debugging SimPy models.
* Two tutorials showing the use of SimPy's advanced object oriented API.
