** 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.
bzr 0.11 2006-10-02
* Smart server transport test failures on windows fixed. (Lukáš Lalinský).
bzr 0.11rc2 2006-09-27
BUG FIXES:
* Test suite hangs on windows fixed. (Andrew Bennets, Alexander Belchenko).
* Commit performance regression fixed. (Aaron Bentley, Robert Collins, John
Arbash Meinel).
bzr 0.11rc1 2006-09-25
IMPROVEMENTS:
* Knit files now wait to create their contents until the first data is
added. The old code used to create an empty .knit and a .kndx with just
the header. However, this caused a lot of extra round trips over sftp.
This can change the time for ``bzr push`` to create a new remote branch
from 160s down to 100s. This also affects ``bzr commit`` performance when
adding new files, ``bzr commit`` on a new kernel-like tree drops from 50s
down to 40s (John Arbash Meinel, #44692)
* When an entire subtree has been deleted, commit will now report that
just the top of the subtree has been deleted, rather than reporting
all the individual items. (Robert Collins)
* Commit performs one less XML parse. (Robert Collins)
* ``bzr checkout`` now operates on readonly branches as well
as readwrite branches. This fixes bug #39542. (Robert Collins)
* ``bzr bind`` no longer synchronises history with the master branch.
Binding should be followed by an update or push to synchronise the
two branches. This is closely related to the fix for bug #39542.
(Robert Collins)
* ``bzrlib.lazy_import.lazy_import`` function to create on-demand
objects. This allows all imports to stay at the global scope, but
modules will not actually be imported if they are not used.
(John Arbash Meinel)
* Support bzr:// and bzr+ssh:// urls to work with the new RPC-based
transport which will be used with the upcoming high-performance smart
server. The new command ``bzr serve`` will invoke bzr in server mode,
which processes these requests. (Andrew Bennetts, Robert Collins, Martin
Pool)
* New command ``bzr version-info`` which can be used to get a summary
of the current state of the tree. This is especially useful as part
of a build commands. See ``doc/version_info.txt`` for more information
(John Arbash Meinel)
bzr 0.10 2006-08-29
IMPROVEMENTS:
* 'merge' now takes --uncommitted, to apply uncommitted changes from a
tree. (Aaron Bentley)
* 'bzr add --file-ids-from' can be used to specify another path to use
for creating file ids, rather than generating all new ones. Internally,
the 'action' passed to smart_add_tree() can return file_ids that
will be used, rather than having bzrlib generate new ones.
(John Arbash Meinel, #55781)
* ``bzr selftest --benchmark`` now allows a ``--cache-dir`` parameter.
This will cache some of the intermediate trees, and decrease the
setup time for benchmark tests. (John Arbash Meinel)
* Inverse forms are provided for all boolean options. For example,
--strict has --no-strict, --no-recurse has --recurse (Aaron Bentley)
* Serialize out Inventories directly, rather than using ElementTree.
Writing out a kernel sized inventory drops from 2s down to ~350ms.
(Robert Collins, John Arbash Meinel)
(BUG FIXES, INTERNALS, and TESTING updates removed from commit message)
artificial neural networks in C with support for both fully connected
and sparsely connected networks. Cross-platform execution in both
fixed and floating point are supported. It includes a framework for
easy handling of training data sets. It is easy to use, versatile,
well documented, and fast. Bindings to other programming languages
and a GUI are also available.
Patch provided by Jukka Salmi via PR 33576.
Changes to the Cyrus IMAP Server since 2.2.12
* Allow sieve scripts to be run on shared mailboxes (via sieve annotation).
* Updated nntpd to be compliant with latest draft (soon to be RFC3977).
* Updated IMAP UIDPLUS extension to be compliant with latest specification
(RFC4315).
* Performance improvements to quota utility.
* Fixed possible race condition in IMAP IDLE.
* Made ptloader runtime configurable.
* Added more extensive output to arbitron.
* Allow responses of any length from backend when proxing IMAP/POP3/NNTP
traffic.
* Added plaintextloginalert option.
* Only allow mbpath to be run as Cyrus user.
* Added berkeley_hash and berkeley_hash_nosync cyrusdb backends (seem to
perform better under heavy loads).
* Added lastpop mailbox annotation.
* Added subscribe/unsubscribe support to cyradm.
* Fixed miscellaneous bugs and build issues.
New in 2.1.22
-------------
* Added support for spliting big data blocks (bigger than maxbuf)
into multiple SASL packets in sasl_encodev
* Various sasl_decode64() fixes
* Increase canonicalization buffer size to 1024 bytes
* Call do_authorization() after successful APOP authentication
* Allow for configuration file location to be configurable independently
of plugin location (bug # 2795)
* Added sasl_set_path function, which provides a more convenient way
of setting plugin and config paths. Changed the default
sasl_getpath_t/sasl_getconfpath_t callbacks to calculate
the value only once and cache it for later use.
* Fixed load_config to search for the config file in all directories
(bug # 2796). Changed the default search path to be
/usr/lib/sasl2:/etc/sasl2
* Don't ignore log_level configuration option in default UNIX syslog
logging callback
* (Windows) Minor IPv6 related changes in Makefiles for Visual Studio 6
* (Windows) Fixed bug of not setting the CODEGEN (code generation option)
nmake option if STATIC nmake option is set.
* Several fixed to DIGEST-MD5 plugin:
- Enable RC4 cipher in Windows build of DIGEST-MD5
- Server side: handle missing realm option as if realm="" was sent
- Fix DIGEST-MD5 to properly advertise maxssf when both DES and RC4
are disabled
- Check that DIGEST-MD5 SASL packet are no shorter than 16 bytes
* Several changes/fixed to SASLDB plugin:
- Prevent spurious SASL_NOUSER errors
- Added ability to keep BerkleyDB handle open between operations
(for performance reason). New behavior can be enabled
with --enable-keep-db-open.
* Better error checking in SQL (MySQL) auxprop plugin code
* Added support for HTTP POST password validation in saslauthd
* Added new application ("pluginviewer") that helps report information
about installed plugins
* Allow for building with OpenSSL 0.9.8
* Allow for building with OpenLDAP 2.3+
