Release notes for the gEDA/gaf 20070526 snapshot
Changes
_________________________________________________________________
libgeda/gschem
* libgeda's shared library version is now 29:0:0.
* Added "recently used files" File menu option. Now you can open up
files you used recently (and if you have a gafrc your components
should be found too) and open those files up in a new gschem
window. (Ivan Stankovic)
* Merge of the noscreen branch (many changes). This branch removed
all cached screen coordinates. Now all calculations are done in
world coordinates and should yield some drawing improvements. End
users should not notice any difference (other than the slight
speed up). (Peter Clifton)
* Many improvements to the "Write image..." dialog box in gschem.
gschem can now export any image that gtk+ (gdk-pixbuf
specifically) can write (png, jpg, ico, bmp, etc...). Libgd is no
longer an optional dependency and cannot be used with
libgeda/gschem. (Carlos Nieves Onega)
* Improved the auto placing mechanism. One improvement (amongst
others) is in the cases of: if the attribute overlap with pins
(including pinnumbers), or the pin connection direction where a
net is supposed to be drawn, then the attributes are moved
automatically. (Carlos Nieves Onega)
* A few improvements to the component place selector including
adding ok button to hide the component insert dialog box).
(Various)
* Added items (links to the wiki and FAQ) to the gschem help menu.
(Peter Brett)
* Fixed a nasty bug that was causing random crashes with keymaps
that did not have a valid keyval/keysym. (Peter Clifton)
* Fixed the drawing of dotted arcs/circles when the dot spacing is
too small to render. (Peter Clifton)
* Fixed component selector filter to be case insensitive. (Carlos
Nieves Onega)
* Added PageUp and PageDown hotkeys to change pages in gschem.
(Peter Brett)
* Fixed the ordering of buttons in all gtk dialog boxes to be
correct (based on what gtk+/gnome/desktop conventions). (Carlos
Nieves Onega)
* Added %%Orientation to DSC block in postscript output. (Mike
Jarabek)
* Fixed color printing of select objects (should not output the
selected color). (Peter Clifton)
* Added hotkeys to decrease and increase the snap grid spacing.
(Carlos Nieves Onega and Peter Brett)
* Improved keymap filling routines (Werner Hoch and Patrick Bernaud)
* Fixed a couple of small memory leaks. (Ales Hvezda)
* The usual slew of bug fixes by many individuals.

* Various language translations updated by various individuals.
gnetlist
* New gnetlist backends written: Calay and Osmond. (John Doty)
* Moved the loading of scheme files using the "-l" command line
before the schematics are loaded (this allows the scheme code to
modify the various search paths).
* Various improvements to the spice-sdb backend including the
treatment of slotted parts (so that pins are emitted in pinseq
order). (Stuart Brorson)
* Added and improved a bunch of regression tests. The vast majority
of these tests are now run during make distcheck. (Stuart Brorson
and Ales Hvezda)
* A few bugs fixed. (Various)
gattrib
* Added doxygen generated docs. (Stuart Brorson)
* A bunch of bugs fixed. (Stuart Brorson and Peter Clifton)
docs
* Removed the html version of the gsch2pcb tutorial. Instead, the
gsch2pcb tutorial is now part of the wiki thanks to several
individuals (Patrick Doyle and Bogdan Petrisor).
* Updated the wiki snapshot to the latest web wiki version. (Ales
Hvezda)
* Misc improvements to various wiki scripts. (Ales Hvezda)
symbols
* Added greek mu character. (Carlos Nieves Onega)
* Added upper case greek omega character. (Jens Persson)
gsymcheck
* No significant changes.
utils
* Added refdes_renum test suite. (Dan McMahill and Stuart Brorson)
* Incorporated --gentle into refdes_renum which doesn't overwrite
refdes'es already numbered. (Stuart Brorson)
* Moved gschemdoc to the gschem package. Bunch of improvements to
the gschemdoc script related to finding local/remote
documentation. (Carlos Nieves Onega)
examples
* Fixed automake infrastructure to install 2N3904 model for the
TwoStageAmp example. (Stuart Brorson)

Nelma is a (command line) tool for numerically calculating various
electrical properties of printed circuit boards or similar objects
composed of conductors and dielectrics (however code is optimized for
circuit board-like geometry).
It is currently capable of calculating capacitances between objects -
nets on a PCB. It returns a spice-compatible description of an
equivalent circuit of stray capacitances that can be for example used
for more accurate circuit simulation. Alternatively it can also
produce field data that can be plotted for example with Gnuplot.
Support for calculating resistances existed for a while but was later
removed because it didn't receive much testing.
Nelma is available under the GNU General Public License version 2.
Release Notes for Icarus Verilog Snapshot 20070227
* Fix some problems with specify block parsing. Detect some cases that
are parsed but not properly implemented yet and issue warnings or
errors. Also fixed a few problems with inertial delay model timing.
* Detect is some cases Verilog source errors that can be better
reported to users. This includes more specific error messages for
certain syntax errors.
* Fix problems with overridden continuous assignments.
* Hide bool types from logic type as far as VPI is concerned, for the
sake of compatibility.
* Fix a variety of code generator expression lifetime bugs that caused
obscure (and wrong) output results in behavioral code.
* iverilog-vpi uses the compiler selected at build time.
* Rework handling of strings to handle escape sequences properly.
* Fix some handling of real values in some expression types.
* Get padding of sized, unsigned numbers when x or z are involved.
* Many, many more misc. bug fixes.
* Add an assert mechinism that improves usefulness of bug reports by
reporting source file line numbers when available.
* Compile fixes, using inttypes.h instead of stdint for portability.
* Various spelling fixes.
LC is simulation tool for the analysis of the electromagnetic
properties of electrical interconnects. The full three-dimensional
circuit is modeled, so all interactions are automatically included in
the solution. The model can be excited by numerous types of waveforms,
and the transient response measured using common values such as
voltage and current. Circuit parameters such as inductance,
capacitance, and impedance can be derived from the transient response,
and frequency-domain results such as S-parameters can also be
calculated. Far field radiation patterns can be obtained.
LC is primarily an electromagnetic simulation and uses the
Finite-Difference Time-Domain (FD-TD) technique. FD-TD is a full wave
explicit solution of Maxwell's equations in three dimensions. In FD-TD,
the rectangular volume enclosing the model is discretized into a large
number of small cells, which may be uniformly-sized, or may vary in size
within the simulation space. The dielectric, permeable, lossy, and
conducting material properties of each cell are incorporated into the
field updates, which are performed iteratively in small time steps.
An interface between the electromagnetic simulation and the circuit
simulation program SPICE is available within LC. This allows the user
to add arbitrary SPICE circuits, such as drivers and loads, into the
interconnect model. The interconnect performance is calculated using
FD-TD while the lumped-element circuits are evaluated by SPICE.
Release Note for Icarus Verilog Snapshot 20070123
Handling of arrays has been rewritten to allow support for net
arrays. This caused ivl_target API changes, as well as elaboration and
vvp run time changes. There may be bits of the old method lingering in
the source code.
Improve support for constant power (**) expressions, and other
constant exppressions that are passed to functions/tasks.
Improve elaboration of for-loop increment expressions. There were some
bugs there that are not fixed.
Fix argument width calculations for shift operations.
Constant ector expressions can have real constants. Handle this at run
time where needed.
Fix some bad lookaside optimizations for assignments to l-value part
selects.

Release Notes for PCB snapshot 20070208
========================================================================
- Add polygon clipping code. This is a big change to how polygons are handled.
The new code now removes islands and correctly identifies open circuits caused
by a trace fully cutting through a polygon. In addition, the RS-274-X output
is now simpler and works with some board houses that use older non-conforming
sofware. Different styles for thermal reliefs are also now supported as part
of the polygon clipper code.
- Add support for plugins
- Many improvements to the autorouter.
- Various improvements to the trace optimizer.
- Add a fontmode for editing pcb fonts
- Add progress() hook to HID structure
- Fix a bug with non-functional windows on some window managers commonly
found on OS-X
- Add support for controlling pcb via dbus
- Fix various bugs which would cause a crash
- Add --scale for postscript scaling
- Intercept window manager delete events with the GTK gui
- Scan the .pcb file for a FileVersion value. This is not written out yet
but will be in future versions.

SimPy 1.8 is a major release with new capabilities, improved documentation
and bug fixes. It is fully backwards compatible with previous versions.
From SimPy 1.8 on, the obsolete Python version 2.2 is no longer supported.
Some of the changes and improvements are:
* New compound yield statements, supporting time-out or event-based
reneging in 'get' and 'put' operations on Store and Level resources.
* yield get on a Store resource can now have a filter function which
selects which and how many items (e.g. "3 parcels weighing less than
3 pounds") should be retrieved.
* The Manual has been thoroughly edited, restructured and rewritten
with a view to greater clarity and readability. It is provided in both
HTML and PDF format.
* The Cheatsheet has been completely rewritten in a tabular format and
reduced to just a few pages. The goal was to turn it into a concise
desktop reference of SimPy commands. The Cheatsheet is provided in both
XLS (MS Excel spreadsheet) and PDF format.
SimPy 1.7.1 is a minor (maintenance) release which fixes a few bugs
in 1.7. The SimPy 1.7.1 API is identical to that of version 1.7.
SimPy 1.7 is fully compatible with version 1.6.1. This major release brings
significant new capabilities for the SimPy modeller and thus a broader
field of applicability to SimPy. It is now very easy to implement models
for scenarios involving:
* producer/consumer relationships between processes,
* multi-process cooperations,
* multi-resource requests, and
* consumable resources.
