Greg Beaver is throwing a "release party" in this new post on his blog today, mentioning the release of PHP_Archive, PHP_LexerGenerator, PHP_ParserGenerator, and, of course, the latest version of PEAR.

Just now, I released new versions of PHP_Archive, PHP_LexerGenerator, PHP_ParserGenerator, and Pierre released a new version of PEAR.

He also outlines the changes is each package, more so PHP_Archve and PHP_LexerGenerator/PHP_ParserGenerator.
