Release Notes for PCB snapshot 20110918
========================================================================
This release represents over 797 commits and as such this summary
clearly is not complete. See the ChangeLog file for the complete list
of changes.
Features
--------
- Internal coordinate space is now metric. This should fix the "trace
nubs on metric grids" issue. Also, units are allowed on pretty much
every "coordinate" that PCB accepts. Example: 5.4in, 10cm, 0.55mm.
New configure option --enable-coord64 to force (slower?) 64-bit type
for coordinates on 32-bit systems (if you need a board bigger than 1
meter across). The internal precision is 1 nanometer, the internal
type is "Coord".
- MinGW support.
- New GL mode for the gtk hid with translucent traces.
- New GTK layer view/choose widget and other GUI enhancements.
- GTK HID warns if the *.pcb file has changed on disk.
- Enhanced grid snapping logic.
- Select/report nets by name.
- Auto-pan has been removed.
- Zoom can zoom out beyond the edge of the board's workspace.
- GTK: title string matches GNOME conventions.
- Personally identifiable information is no longer stored in the PCB.
- Toggling vias from hole to plated is reversible.
- Gerber exporter has options for including outlines on other layers.
- Edited footprint files are saved as footprints, not pcbs.
- Improved gtk library search/filter.
- Default layer stack is now a six-layer template with outline.
- If the board has an outline layer, an outline will be shown if no
other outline is specified.
- Group[] string allows t/b synonyms for c/s. "top" and "bottom" are
the standard names now.
- PCB will save files with an older version tag if newer features aren't needed.
- Autorouter has a progress dialog.
- PCB will no longer let you delete the last top/bottom layer.
- Refcard has been updated.
- Documentation updates.
- Layes with the PCB::skip-drc attribute set are ignored during DRC.
- Allow numeric keys to also choose the silk layer.
- Minor readability tweaks to the default font.
- Via copper may overlap.
- User is notified if an Import() cannot find all the footprints.
Bug Fixes
---------
- Optimizer won't try to optimize overlapping pads
- Undo should fail less, in corner cases.
- Nested key-bound actions won't crash lesstif.
- Do not select invisible pads on the far side.
- Protect Import() from command injection.
- Fix conversion of far-side polygons to element pads.
- Fix initial clearance values of text when loading PCBs.
- Fix solder mask drawing on vias.
- Add missing action documentation.
- Fab drawing notes actual outline trace width.
- Zero clearance pins and pads won't cause DRC failures.
- PS export: fix draw-rectangle (used to do fill, not outline)
- Gerber export no longer fills unfilled rectanges.
- If there are no image formats available, the PNG hid is not enabled.
- You can no longer select pins/pads of locked elements.
- The m4-to-newlib converter now creates file names that match the
library view.
- Never set the FOUND flag on new silk lines.
- Lesstif HID won't crash if both Xinerama and XRender are detected.
- Lesstif menu is now internationalizable.
- Refdes labels in a font-less layout can be moved.
- Import can correctly update elements on the bottom side.
- DRC no longer treats unplated holes as conducting.
Other
-----
- Updated and new translations, including Dutch.
- Many polygon speedups.
- Numerous build-related cleanups.
- Numerous minor speed-related cleanups.
- GTK 2.18 is the minimum required version.
- GTS moved out of the src/ tree so it can be built with different flags.
- More C++ compatible.
- Expanded regex documentation.
- Much code which is no longer needed has been removed.
- HID init method changed to allow for hid struct expansion without
breaking everything.
- New HID calls for whole-pad and whole-pin drawing.
- ClearAndRedrawOutput() replaced with Redraw().
- Board objects use hashes instead of lists to store parts, so
pointers don't change.
- DVI documentation output is no longer generated.

that I haven't yet tracked down or pinned on guile-gnome-platform or anything else.

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.

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.
