to the SVN at
http://svn.gnome.org/viewcvs/libxml2/trunk/
code base.Here is the list of public releases:
2.7.0: Aug 30 2008:
- Documentation: switch ChangeLog to UTF-8, improve mutithreads and
xmlParserCleanup docs
- Portability fixes: Older Win32 platforms (Rob Richards), MSVC
porting fix (Rob Richards), Mac OS X regression tests (Sven Herzberg),
non GNUCC builds (Rob Richards), compilation on Haiku (Andreas Färber)
- Bug fixes: various realloc problems (Ashwin), potential double-free
(Ashwin), regexp crash, icrash with invalid whitespace facets (Rob
Richards), pattern fix when streaming (William Brack), various XML
parsing and validation fixes based on the W3C regression tests, reader
tree skipping function fix (Ashwin), Schemas regexps escaping fix
(Volker Grabsch), handling of entity push errors (Ashwin), fix a slowdown
when encoder cant serialize characters on output
- Code cleanup: compilation fix without the reader, without the output
(Robert Schwebel), python whitespace (Martin), many space/tabs cleanups,
serious cleanup of the entity handling code
- Improvement: switch parser to XML-1.0 5th edition, add parsing flags
for old versions, switch URI parsing to RFC 3986,
add xmlSchemaValidCtxtGetParserCtxt (Holger Kaelberer),
new hashing functions for dictionnaries (based on Stefan Behnel work),
improve handling of misplaced html/head/body in HTML parser, better
regression test tools and code coverage display, better algorithms
to detect various versions of the billion laughts attacks, make
arbitrary parser limits avoidable as a parser option
2.6.32: Apr 8 2008:
- Documentation: returning heap memory to kernel (Wolfram Sang),
trying to clarify xmlCleanupParser() use, xmlXPathContext improvement
