On the PEAR blog today there's an update about the migration over to github that 5 million lines of code has already made:

Since October 2011, 5 million lines of the PEAR codebase has shifted to github. Hand in hand with this shift has been the tireless work of Daniel C - someone who brazenly said "I will fix the failing packages!" in the tail end of last year.

As a result of his efforts a list has been created of known good packages to use with PHP 5.4. Other results include:

• All test infrastructure upgrading to PHP 5.4 release candidates
• All database driven test suites executing properly, catching a variety of simple bugs
• Hitting a point of "near zero" patches to be applied to unmaintained packages
• Increasingly, the PEAR QA team is delivering PHP 5.3+ friendly forks of existing packages
