** Release Notes for Icarus Verilog 0.8.3
This is a new release of the stable 0.8 branch. The changes from 0.8.2
are intended to be evolutionary, rather then revolutionary, to enhance
the stability of the branch.
Various simulator bugs have been fixed, including (but not limited to):
- Detect overrun of timescale vs. precision
- Handle more operators in constant expressions
- Various ivl crashes and panics fixed.
- Some performance bottlenecks have been fixed.
- Various tool compilation problems have been fixed.
Also, the internal synthesizer (for synthesis targets) has been
considerably improved. NOTE that the code generators have not been
improved to take advantage of all the changes here, so there is work
yet to be done.
The mingw build process for compiling in Windows has been reworked. It
is now possible (indeed preferable) to compile fully native Icarus
Verilog binaries on Windows with no Cygwin tools at all.

Release notes for the gEDA/gaf 20060824 snapshot
Changes
_________________________________________________________________
libgeda/gschem
* Updated libgeda's so version to 26:0:0.
* Fixed the infamous "slice" memory problem that was plaguing
gEDA/gaf for a while. Mixing malloc/free and g_malloc/g_free is a
bad idea and also setting a field in deallocated memory tends to
upset glib's memory management.
* Added a new rc variable called "always-promote-attributes" that
takes a string of attribute names that are automatically prompted
when a component is placed on a schematic. The default list is:
"footprint device value model-name".
* Newly rewritten postscript output to be much more compact, sane.
and support unicode (Mike Jarabek).
* gschem now uses stock gtk+ icons if they are available (Tomaz
Solc).
* Improved the robustness of the loading of symbols/schmeatics
(Tomaz Solc).
* Added support for panning using the middle mouse button and
controlling the amount of pan (Peter Clifton).
* Changed the default behavior of the middle button (now mouse pan).
* Added cursor key panning in gschem and rc keywords for controling
the amount of pan (Tomaz Solc).
* Added the ability to zoom in and zoom out using the mouse wheel
(Peter Clifton).
* Added a bunch of new hooks to gschem and libgeda. This supports
various new features such as auto pin attributes, auto attribute
placing (currently commented out), select_component_hook,
select_net_hook, deselect_component_hook, deselect_net_hook,
deselect_all (Carlos Nieves Onega and Dan McMahill).
* Added support for dragging an object using the first mouse button
in gschem (Carlos Nieves Onega).
* Added the beginnings of pcb mode to gschem (Dan McMahill).
* Improvements to the autosave and backup mechanism (Carlos Nieves
Onega).
* Added support for text overbars. The delimiter character is \_ (it
should be at the beginning and end of the where you want the
overbar to be (Carlos Nieves Onega). Postscript output support for
overbars (Mike Jarabek).
* Bug fixes to the auto save mechanism (Carlos Nieves Onega). Please
report any more crashes.
* Fixed component update to work correctly since it was looking for
existing attributes in the wrong places.
* Converted all the noweb code to just plain C (making sure that all
the really nice documentation that Patrick and others is
perserved). gEDA/gaf no longer requires noweb to build (Jason
Childs).
* Removed all pre-GTK 2.x code from gEDA/gaf (Peter Brett).
* Translation updates from various people.
gnetlist
* DRC2 backend bug fixes and improvements (Carlos Nieves Onega).
* Various bug fixes (Werner Hoch and others).
gattrib
* Fixed annoying bug in which gattrib soaked up 70% of processor
time (Stuart Brorson).
* Implemented ability to export CSV file of component sheet (Stuart
Brorson).
* Made cell text different colors depending upon attribute
visibility (Stuart Brorson).
* Applied patch to handle attrib strings with multiple = signs
(Stuart Brorson and Jeff Mallatt).
* Misc bug fixes (Stuart Brorson).
symbols
* Many symbol bug fixes and improvements (Werner Hoch and others).
* Improved the NC symbols so that the drc2 backend handles no
connect situarions better (Carlos Nieves Onega).
gsymcheck
* Various bug fixes and improvements (Carlos Nieves Onega and
others).
utils
* gsch2pcb improvements dealing with how to find gnetlist
executable.
* Updated to the latest version of grenum (Levente Kovacs).
* Applied power pin handling patch (Patrick Doyle).
docs
* Obsoleted all latex documentation and replaced it with a snaphot
of the gEDA wiki. Many thanks to David Hart for the conversion and
necessary support to make this conversion possible.
examples
* No significant changes.
misc
* The geda (gManager) source tarball is not longer being
distributed. All the code is still in the CVS repository, but due
to lack of maintanance, it has been pulled for these snapshot
releases.
* Fixed various Makefiles to support make distcheck again.
* Lots of bug fixes by (Werner Hoch, Carlos Nieves Onega, and many
others).
For more a detailed changes, please look in the appropriate ChangeLogs
in the source tarballs.

last packaged snapshot. Those are:
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060215
--------------------------------------------------
* Part select of memory words should now work according to
Verilog-2001. This also led to some cleanup of the handling of types
internally, as well as some infrastructure for general arrays.
* Minor fix to parsing of (* *) attributes.
* Fix rounding of reals to integers.
* Clean up some of the vvp engine related to memories. Remove some
dead instructions.
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060409
--------------------------------------------------
the most substantial difference in this snapshot the first signs of
generate support. The compiler now supports generate loops and has
been tested with examples that include wires and gates within the
generate scheme. The regression test suite has very few generate
tests, so any concise self-testing test programs that use generate
would be helpful.
Also, instance arrays that use overridden parameters now work
properly.
Task arguments are a bit more flexible in order to support vendor
(notably Xilinx) models that use more interesting task arguments.
Runtime support for bi-directional ports had some bugs fixed, along
with some other minor run-time bugs. Also, the runtime gains support
for typed parameters. And also, there are some new runtime callbacks
for events and memories.
Parameters had a few types related bugs fixed. They are a bit more
flexible now.
And various minor compilation errors have been fixed. This includes
C/C++ compilation errors fixes, and some configure/Makefile tweaks.
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060618
--------------------------------------------------
Add support for system functions in continuous assignments.
Allow concatenations as arguments to inout ports. This comes with a
small variety of internal part select and concatenation bug fixes.
Fix some bugs in constant propagation through ternary expressions.
Fix broken subtraction if small constants in certain cases.
Fix a few datatype mismatch errors.
Make $readmem give warning when input is inadequate for requested
range.
Fix runtime of nand in continuous assignments.
Fix synchronous user defined primiteves to only follow edges.
Fix a runtime error in some thread delays processing.
Improve limited genvar expression handling.
Start a rework of expression elaboration. Make elaboration aware of
the expression context width when appropriate in order to better
handle expression width and padding.
Fix the make rules for parse.cc to reflect that they come from the
same source. Fix the autoconf.sh to configure the stub target.
Fix portability of the lexor source files on Windows systems. Get rid
of the isatty references.
Make a stub lround when the system version is missing.
--------------------------------------------------
* Release Notes for Snapshot 20060809
--------------------------------------------------
Some handling of real values is improved. Real valued literals are
handled in net contexts (continuous assignment, etc.). Also, modulus
of real operands now works. (This is an extension to the Verilog
standard.)
The power operator (**) now works.
Signed right shift works properly now.
The $sscanf and $fscanf are introduced, and work at least for basic
numeric values.
The release function now works to undo general force statements, and
not just contant force statements.
Delay constants up to 64 bits are supported. This at first doesn't
seem like an issue, but when precisions are mixed, it becomes
surprisingly easy to overflow 32bit delays.
The driver is reworked to pass many preprocessor details through a
temporary file instead of on the command line of a system(3)
call. This prevents confusing and incorrect shell processing of
complex strings passed as values to -D flags.
Various other little fixes.
Changes are:
* Removed all build support for GTK1.
* Dino Ghilardi fixed log.c (the last reminder of GTK1) so
log windows popup don't crash gerbv anymore.
* Dan McMahill added the GCC4 patch.
* Renamed stack_t to macro_stack_t to support darwin/MacOS X
pointed out by Daniel Mack.
* Changed build system to suit new autoconf/automake versions.
Caused gerbv not to find init.scm.
* Fixed a bug so gerbv can handle negative coordinates when using
trailing zeroes.
* Better checking of return values for errors.
* Use setlocale explicit so your locale doesn't screw up sscanf
and strtod to use comma (,) instead of dot (.).
* For distributions there is a new directory called desktop, where
gerbv.desktop and gerbv.png is stored for desktop settings.
Submitted to Debian bug list from Vassilis Pandis for Ubuntu.
since they always need a C compiler, even when the source code is
completely in C++.
For some other packages, stated in the comment that a C compiler is
really not needed.
had actually been ignoring LTCONFIG_OVERRIDE anyway and just using
the default LIBTOOL_OVERRIDE to replace libtool scripts in packages.
This just formalizes the fact that LTCONFIG_OVERRIDE is not used
meaningfully by pkgsrc.
Many improvements since the last packaged version including, but not limited
to:
- enhanced transient timestep control algorithm which is significantly more
accurate than spice now.
- enhanced compatibility with hspice netlists
- named nodes (as opposed to numbered only nodes) work now
- improvements to the bsim3v3 model support
- migration from a custom build system to a GNU autoconf/automake based build
system.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
1.5.4 release was something of a toy, QCad was thoroughly reworked for 2.0
and could now be called usable for many practical purposes.
Versions 2.0.4.0 (initially) to 2.0.5.0 have been usable in wip for a bit
more than a year, and so seem ready to import.
"Yes, that should be fine. Please watch the bulk builds for it and
try to fix any problems that might appear." -wiz@
Updates to pkglint now produce some new suggestions, which I will make and
commit after confirming they don't break anything; at least this version I
already know to build successfully for me.
