libass is a portable subtitle renderer for the ASS/SSA (Advanced
Substation Alpha/Substation Alpha) subtitle format. It is mostly
compatible with VSFilter.
GNU libmicrohttpd is a small C library that is supposed to make it
easy to run an HTTP server as part of another application. GNU
libmicrohttpd is free software and part of the GNU project. Key
features that distinguish libmicrohttpd from other projects are:
* C library: fast and small
* API is simple, expressive and fully reentrant
* Implementation is HTTP 1.1 compliant
* HTTP server can listen on multiple ports
* Four different threading models (select, poll, pthread, thread pool)
* Supported platforms include GNU/Linux, FreeBSD, OpenBSD, NetBSD, OS X, W32,
Symbian and z/OS
* Support for IPv6
* Support for SHOUTcast
* Support for incremental processing of POST data (optional)
* Support for basic and digest authentication (optional)
* Support for SSL3 and TLS (requires libgcrypt and libgnutls, optional)
* Binary is only about 32k (without TLS/SSL support and other optional
features)
Version 1.5.3beta11 [June 11, 2011]
Fixed png_handle_sCAL which is broken in 1.5; added sCAL to pngtest.png
Revised documentation about png_set_user_limits() to say that it also affects
png writing.
Revised handling of png_set_user_limits() so that it can increase the
limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only
reduce it.
Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
wrong in 128 out of 65536 cases. Getting the right answer all the time
without division is easy.
Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro.
Added projects/owatcom, an IDE project for OpenWatcom to replace
scripts/makefile.watcom. This project works with OpenWatcom 1.9. The
IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
The project is configurable, unlike the Visual Studio project, so long
as the developer has an awk.
Changed png_set_gAMA to limit the gamma value range so that the inverse
of the stored value cannot overflow the fixed point representation,
and changed other things OpenWatcom warns about.
Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows
pngvalid to build when ALPHA_MODE is not supported, which is required if
it is to build on libpng 1.4.
Removed string/memory macros that are no longer used and are not
necessarily fully supportable, particularly png_strncpy and png_snprintf.
Added log option to pngvalid.c and attempted to improve gamma messages.
Version 1.5.3 [omitted]
People found the presence of a beta release following an rc release
to be confusing; therefore we bump the version to libpng-1.5.4beta01
and there will be no libpng-1.5.3 release.
Version 1.5.4beta01 [June 14, 2011]
Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED
to get the same (inaccurate) output as libpng-1.5.2 and earlier.
Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE
outside of an unknown-chunk block in png.h because they are also
needed for other uses.
Version 1.5.4beta02 [June 14, 2011]
Fixed and clarified LEGACY 16-to-8 scaling code.
Added png_set_chop_16() API, to match inaccurate results from previous
libpng versions.
Removed the ACCURATE and LEGACY options (they are no longer useable)
Use the old scaling method for background if png_set_chop_16() was
called.
Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED
Version 1.5.4beta03 [June 15, 2011]
Fixed a problem in png_do_expand_palette() exposed by optimization in
1.5.3beta06
Also removed a spurious and confusing "trans" member ("trans") from png_info.
The palette expand optimization prevented expansion to an intermediate RGBA
form if tRNS was present but alpha was marked to be stripped; this exposed
a check for tRNS in png_do_expand_palette() which is inconsistent with the
code elsewhere in libpng.
Correction to the expand_16 code; removed extra instance of
png_set_scale_16_to_8 from pngpriv.h
Version 1.5.4beta04 [June 16, 2011]
Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c
Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms.
Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is
not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built.
Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8
Version 1.5.4beta05 [June 16, 2011]
Renamed png_set_strip_16() to png_set_scale_16() and renamed
png_set_chop_16() to png_set_strip(16) in an attempt to minimize the
behavior changes between libpng14 and libpng15.
Version 1.5.4beta06 [June 18, 2011]
Fixed new bug that was causing both strip_16 and scale_16 to be applied.
Version 1.5.4beta07 [June 19, 2011]
Fixed pngvalid, simplified macros, added checking for 0 in sCAL.
The ACCURATE scale macro is no longer defined in 1.5 - call the
png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined
if the png_strip_16_to_8 API is present. png_check_fp_number now
maintains some state so that positive, negative and zero values are
identified. sCAL uses these to be strictly spec conformant.
Version 1.5.4beta08 [June 23, 2011]
Fixed pngvalid if ACCURATE_SCALE is defined.
Updated scripts/pnglibconf.h.prebuilt.
Version 1.5.4rc01 [June 30, 2011]
Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400.
Version 1.5.4 [July 7, 2011]
no changes.
== 2.3 ==
2.3.1.1 Sun Jun 19 2011 Toni Gundogdu
Fixes:
- Missing details in --help output
2.3.1 Sat Jun 18 2011 Toni Gundogdu
Changes:
- Add --query-formats, deprecate "--format list"
- Detect quvi and/or download command from $PATH
- In the absence of --quvi and/or --get-with
- Bump quvi prerequisite to 0.2.17
- Revise manual
* Various git-svn updates.
* Updates the way content tags are handled in gitweb. Also adds
a UI to choose common timezone for displaying the dates.
* Similar to branch names, tagnames that begin with "-" are now
disallowed.
* Clean-up of the C part of i18n (but not l10n---please wait)
continues.
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Pushing and pulling from a repository with large number of refs that
point to identical commits are optimized by not listing the same commit
during the common ancestor negotiation exchange with the other side.
* Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
using "git add" will send the contents straight to a packfile without
having to hold it and its compressed representation both at the same
time in memory.
* Processes spawned by "[alias] <name> = !process" in the configuration
can inspect GIT_PREFIX environment variable to learn where in the
working tree the original command was invoked.
* A magic pathspec ":/" tells a command that limits its operation to
the current directory when ran from a subdirectory to work on the
entire working tree. In general, ":/path/to/file" would be relative
to the root of the working tree hierarchy.
After "git reset --hard; edit Makefile; cd t/", "git add -u" would
be a no-op, but "git add -u :/" would add the updated contents of
the Makefile at the top level. If you want to name a path in the
current subdirectory whose unusual name begins with ":/", you can
name it by "./:/that/path" or by "\:/that/path".
* "git blame" learned "--abbrev[=<n>]" option to control the minimum
number of hexdigits shown for commit object names.
* "git blame" learned "--line-porcelain" that is less efficient but is
easier to parse.
* Aborting "git commit --interactive" discards updates to the index
made during the interactive session.
* More...
Modules:
* New LDAP option OPT_X_TLS_PACKAGE available in OpenLDAP 2.4.26+
to determine the name of the SSL/TLS package OpenLDAP was
built with
Lib/

case_ignore_attr_types used to define attribute types for which
comparison of old and new values should be case-insensitive
* Minor changes to which data is sent to debug output for various
trace levels
* Now tag [1] is used in ldap.extop.dds.RefreshResponse in
compliance with RFC 2589 (fix available for OpenLDAP ITS-6886)
* New sub-module ldap.controls.sessiontrack implements request control
as described in draft-wahl-ldap-session (needs pyasn1_modules)
Changes since 2.4.0:
* OpenLDAP 2.4.11+ required to build
* Support for extracting LDAPv3 extended controls in
LDAP_RES_SEARCH_ENTRY responses
(see SF-2829057, thanks to Rich)

Lib/
* new class API in ldap.controls, not backwards-compatible!
* new sub-modules for ldap.controls, some require pyasn1 and pyasn1_modules
* New methods LDAPObject.result4() and LDAPObject.extop_result()
* New (optional) class ldap.controls.AssertionControl
* New helper module ldap.logger contains file-like object which
sends trace messages to logging.log()
* Removed non-functional method LDAPObject.set_cache_options()
* Removed unused dictionary ldap.controls.knownLDAPControls
Modules/
* ldapcontrol.c: Fixed encode_assertion_control() and function is no longer
hidden behind ifdef-statement
Changes:
- Added "jet bundle" framework by Werner Seiler and Joachim Schue,
which includes completion procedure and symmetry analysis for PDE.
- Better splitting of group representations (added Holt-Rees improvement
to meatAxe).
- Added numeric versions of some elliptic integrals and few more elliptic
functions.
- Speeded up FFCGP (finite fields via Zech logarithms).
- New experimental flag (off by default, set via setSimplifyDenomsFlag)
which if on causes removal of irrationalities from denominators.
Usually it causes slowdown, but on some examples gives huge speedup.
It may go away in future (when no longer needed).
- Added experimental framework for theory of computations.
Bug fixes, in particular:
- Numerical solutions of polynomial systems have now required accuracy
(SF 2418832).
- Fixed problem with crashes during tracing.
- Fixed a problem with nested iteration (SF 3016806).
- Eliminated stack overflow when concatenating long lists.

* kadmind frees invalid pointer [MITKRB5-SA-2011-004 CVE-2011-0285]
Interoperability:
* Correctly encrypt GSSAPI forwarded credentials using the session key, not
a subkey.
* Set NT-SRV-INST on TGS principal names as expected by some Windows Server
Domain Controllers.
* Don't reject AP-REQ messages if their PAC doesn't validate; suppress the PAC
instead.
* Correctly validate HMAC-MD5 checksums that use DES keys
What's new in 1.5 rc3
=====================
Pertinent to users:
-------------------
1. PyBlosxom shows an error page if it crashes rather than forcing
you to go figure out what happened by finding the web server logs.
This should make configuring and debugging much easier.
2. Bunch of new plugins.
3. Bunch of fixes to the comments plugin, tags and pycalendar plugins.
Tags plugin gains tags cloud functionality.
Comments plugin gains comment_disable_after_x_days feature.
If you're using them, update to the latest versions.
4. Bunch of fixes to the documentation. If you see errors or things
that are unclear, let us know.
The documentation for the comments plugin still needs to be overhauled.
5. Bunch of other bug fixes.
6. Bunch of new plugins: magicword, pages, rst, check_nonhuman, and
check_blacklist.
New features
* Support for reading MIT database file directly
* KCM is polished up and now used in production
* NTLM first class citizen, credentials stored in KCM
* Table driven ASN.1 compiler, smaller!, not enabled by default
* Native Windows client support
Notes
* Disabled write support NDBM hdb backend (read still in there) since
it can't handle large records, please migrate to a diffrent backend
(like BDB4)
Changes 1.3.3:
Bug fixes
* Check the GSS-API checksum exists before trying to use it [CVE-2010-1321]
* Check NULL pointers before dereference them [kdc]
Changes 1.3.2:
Bug fixes
* Don't mix length when clearing hmac (could memset too much)
* More paranoid underrun checking when decrypting packets
* Check the password change requests and refuse to answer empty packets
* Build on OpenSolaris
* Renumber AD-SIGNED-TICKET since it was stolen from US
* Don't cache /dev/*random file descriptor, it doesn't get unloaded
* Make C++ safe
* Misc warnings
