User experience improvements
----------------------------
- reorchestrated the closing of the command window to not crash.
- only invalidate the screen after changes to the crosshair or mark are
complete.
Plugins
-------
- none
Exporters
---------
- fix for gcode dimensions.
- added a regression test for the IPC-D-356 exporter.
- added more documentation for the IPC-D-356 netlist exporter.
Footprints library
------------------
- add macro with more programmability for 2 pin axial components. Use
this to add a few IPC-7251 compliant footprints for axial inductors,
horizontally mounted. Use this in turn for the TDK B82145A RF chokes
family.
- add toko category and the 7P variable inductors.
- gen_geda_*.awk were nearly identical to gen_*.awk so add 2 lines to
geda.inc so we can use the same script for everything. Verified that
pcblib-newlib builds with identical results before/after.
- for the horizontally mounted axial macro add the missing bits for
marking polarity on parts like diodes.
- add PKG_RADIAL_MM100 macro for doing more general metric 2 pin radial
packages.
- add some IPC radial capacitor footprints and use those to create some
united chemicon footprints.
- add DO-41 diode package, horizontally mounted.
- add PKG_MTHOLE_GENERIC macro for fairly generic mounting holes. Use
this to define IPC mounting holes for #4 and #6 machine screws with
pan heads or flat washers for both "tight" (board < 4") and "loose"
(board > 4") fits.
- add TO-263 footprint.
- add some notes about m4 library development.
- fix problem in some possible invocations of the generic mounting hole
macro. All footprints pass syntax checks again.
- remove an extra empty attribute which is not needed and causes
warnings in the mounting hole macro.
- fix clearance on the Toko 7P footprint.
- in the mounting hole macro, change the calculation of the pad size for
the support vias to make them as large as possible without actually
changing the copper (the support vias are covered by the main pad).
This does not affect the fabricated board but it does remove some
false positive DRC complaints.
Developer experience improvements
---------------------------------
- allow translators to change number of tabs in message.
- In the test suite, check for a working X display using xhost before
running action script tests
- match() with 3 arguments is a gawk extension. Rework the code to avoid
using a 3 argument call to match() in one spot. Lets the script run
with gawk or NetBSD's awk (20121220). Verified that the generated
result is identical to the previous gawk result using both gawk and
NetBSDs awk.
- change from AC_FD_CC to AS_MESSAGE_LOG_FD
- removed the antifork abomination.
- disabled one of the checks used to deal with older gdlib installs on
some linux systems when building under cygwin as the test has
problems. Repairs building for mingw under cygwin.
- when building under cygwin, create a pcbtest.bat batch file that
allows testing the compiled pcb without installing. This is somewhat
analogous to the pcbtest.sh script generated on linux and other
unix-like systems.
- cleanup the win32 build script a good bit. An important change is
that instead of blindly installing all of the mingw cross system root
files, only install a set of listed ones. This not only reduces the
size of the windows installer but makes sure we have a more repeatable
build and know what we are actually bundling into the installer.
- fixed the Attribute deletion code.
Notes for early adapters
------------------------
- none
Changed dependencies
--------------------
- none
Fixed and committed Launchpad bug reports
-----------------------------------------
#700193 Append branch to version string.
#917308 m4lib_to_newlib.sh does not work with mawk.
#1528040 Gcode export smaller pad size.
#1654821 Attribute deletion code is broken.
#1659045 gts source do not compile when DEBUG symbol defined.
#1659061 Compile warnings when DEBUG symbol is defined.
#1660058 Several i18n fixes.
#1672886 Crash when reopening command entry window in gtk.
#1674133 Last action executed when escaping from command entry.
#1682654 Drawing area redrawn twice when crosshair moves.
========================================================================
3.3.86 03oct17 Added recurse import function (found before only in the hier
search) into the SST.
Removed obsolete bundle functionality from SST as recurse
import more accurately imports recursively.
Made entrybox taller (using -1) as recent versions of
gnome have taller window titlebars and the widget was not
tall enough.
3.3.84 03sep17 Updated FSDB reader with experimental FST tree build
routines for faster init.
Removed warnings found when compiling with -Wshadow.
Automatically enable --comphier for FST/FSDB/AE2 if facility
count reaches 500000. This is to reduce memory consumption
for traces with very many signals. Added disable_auto_comphier
to override this behavior.
Fix null pointer sent to gtk_clipboard_set_text() for
mouseover to clipboard cut ops.
- Fix issue of raise exception when sweep along with cornered line
- osx ifx: Visualization, Font_FontMgr - do not look for fonts.dir on OS X
- fix external linkage error in BRepBuilderAPI_Copy
-----------------------------
3.3.83 04aug17 Preserve search type for regex search across reloads or
close/reopens of regex search widget.
Update local libz to current version.
-----------------------------
3.3.82 02jul17 Get sys_fst working with VCS VPI.
Added string concatenations for vectors.
Added asserts to ghwlib.c to make scan-view clean.
----------------------------
3.3.81 09jun17 Added max_fsdb_trees environment variable.
Fixed -C option so it is persistent across new tabs.
Integrated updated GHW reader code.
- Added missing ErrorStatus function in BRepLib_CheckCurveOnSurface
- Install Shaders directory to resource folder
- Fix normals of generated VTK polydata
- prevent DRAWEXE from being added to OCE_LIBRARIES (issue #660)
- Fix warnings with VTK 7.1
- Fix missing include and other minor header issues
- Fix clockget_time detection on osx
-----------------------------
3.3.80 17mar17 Added "/View/Mouseover Copies To Clipboard" menu option to
allow copying values into the clipboard so they can be pasted
into text editors, etc.
----------------------------
3.16.7 (2017/03/21)
Bug fixes:
FS#1560 - Main menu not selectable (Ubuntu 16.04, Unity)
FS#1561 - Edit > Drawing Preferences: menu missing (macOS, French locale)
------------------------------
(from: http://klayout.de/development.html)
Version 0.24.10
Release date: 2017-04-01
Features:
Enhancements: New method CellView#is_dirty? This method indicates
that a cell view needs saving
Bugfix: DEF reader was not able to read routing Routed segments
with vias plus continued wiring were not read. Instead an error
message was shown saying "Invalid orientation specification"
Bugfix: Setting "technology-data" configuration property did not
work Reading or writing the "technology-data" configuration
property is the only way to access technology data from a
script. Hence it's important that this property can be set. With
this patch, "technology-data" can be set to an XML string which
has the same format than the one stored within the configuration
file.
Bugfix: Reader issues with some RVE files The RVE reader could not
read files with cell names containing hyphens (like "A-B").
Bugfix: Inplace operators are now working in Python too For
example "r1 += r2" was not working (r1 and r2 are pya.Region
objects for example).

SOLVESPACE is a parametric 3d CAD program. Applications include:
modeling 3d parts - draw with extrudes, revolves, and Boolean
(union / difference) operations
modeling 2d parts - draw the part as a single section, and export
DXF, PDF, SVG; use 3d assembly to verify fit
3d-printed parts - export the STL or other triangle mesh expected
by most 3d printers
preparing CAM data - export 2d vector art for a waterjet machine
or laser cutter; or generate STEP or STL, for import into
third-party CAM software for machining
mechanism design - use the constraint solver to simulate planar
or spatial linkages, with pin, ball, or slide joints
plane and solid geometry - replace hand-solved trigonometry and
spreadsheets with a live dimensioned drawing

Release notes for pcb-4.0.0
========================================================================
Dear Users,
It has been quite some time since the last snapshot of pcb was released
in March 2014.
Since then quite a lot of bugs were fixed and new features added, below
this introduction a summary is given of the improvements and additions
since the latest snapshot "pcb-20140316".
This release represents over 480 commits (mostly bugfixes and code
refactoring) and as such this summary clearly is not complete.
This pcb release 4.0.0 has a significant change in the major version
number.
This is done to make a fresh start and to get away from the 1.99z
version with YYYYMMDD snapshots.
Kind regards,
The pcb development team
User experience improvements
----------------------------
- added the command-line option --save-metric-only.
- added escaping of Attribute values.
- added a translation of the Getting Started with PCB for pt_BR.
- added translatable tooltips for toolbar buttons.
- added "Report net length" to Menu -> Info in Gtk.
- added a script for generating a key binding list.
- added tooltips in the GTK HID UI.
- the puller no longer crosses unplated holes.
- solder/component outer layer names changed to top/bottom.
- pcb now uses a tilde instead of a dash for backup filenames.
- corrections in the user documentation.
- the position "delta" display no longer forces the GTK HID window to
grow.
- write time in ASCII locale into exported files.
- allow for up to 10000 dpi on png exporter output.
Plugins
-------
- added smartdisperse for dispersing elements better, contributed by
Ben Jackson.
- added relocate for relocating elements, contributed by Jean Richard.
- added RenumberBlock() and RenumberBuffer(), contributed by DJ Delorie.
- added teardrops(), contributed by DJ Delorie.
Exporters
---------
- added a netlister conforming to the IPC-D-356 standard, contributed by
Jerome Marchand.
- changed "as-shown" to "screen-layer-order" in the png and eps hids.
Footprints library
------------------
- added a SC88A footprint.
- added a LQFP80-10 footprint.
- added QFN24_5 and TQFN24_5 footprints.
- added a SOD523 footprint.
- the SOT325 package had a wrong numbering.
- renamed the SOT325 footprint to SOT353.
- in the ALF footprint the drill holes were too tight.
- an infinite loop in the SIL m4 macro was fixed.
Developer experience improvements
---------------------------------
- made a start with adding Doxygen developer documentation tags in the
source files.
A pcb.dox configuration file is available in the "doc/doxygen"
directory so developers can build the documentation there by invoking
"doxygen pcb.dox" from the CLI.
This is not done by configuring with --enable-docs, which is solely
reserved for the generation of User documentation.
- added numerous fixes in the win32 target.
Notes for early adapters
------------------------
In the git repository two tags have been added to allow for checking
out of pcb-4.0.0 at the branch point (git checkout pcb-4.0.0-base) or at
the release point (git checkout pcb-4.0.0-RELEASE).
This is in line with tagging done in former snapshots.
Changed dependencies
--------------------
- autoconf 2.60 --> 2.69.
- gettext 0.14 --> 0.19.3.

-----------------------------
From: http://klayout.de/development.html
Release date: 2016-11-29
Enhancements: The RBA::Region#smooth function was enhanced to give
somewhat better results
Enhancements: DXF's circle approximation can now also specified
through an "accuracy" parameter: if less than the number of specified
points is required to achieve the given accuracy, the number is
reduced accordingly. This also applies to the polygon interpolation
of spline and arc curves.
Enhancement: RBA integration now is compatible with Ruby 2.3 which
allows building on Ubuntu 16 as well.
Enhancement: OASIS files with instance angles >360 were rejected
before. Now, this has turned into a warning.
Bugfix: DEF reader was failing to read MASK/via combinations.
Bugfix: The marker browser's "show only rules with errors" option was
enabled again on sorting of errors.
Bugfix: DRC: Using Layout objects for inputs didn't work
Bugfix: Copying Hierarchy treets containing PCell's made the PCell's
being turned into static cells.
-----------------------------
3.3.79 31dec16 Disable accelerator keys in twinwave single window mode to

Added fill_waveform rc variable and corresponding menu option
(/View/Show Filled High Values) to allow filling in the lower
portion of high values for increased visibility.
