On the PEAR Group blog there's a new post welcoming all new contributors to the project and pointing out that the PEAR account on Github has officially passed the 200 repository mark in the move from SVN to Git.
PEAR is about providing the PHP community with reusable, effective components - this has been our mission since day 1. If there is anything we can do to make that goal happen, to assist you as an individual or company, I would strongly encourage you to let us know - we're here to help.
They mention the work of two individuals that have done good work on a specific package, meldra and Gemorroj - perfect examples of how the move to Github has made it simpler to implement changes that have been "waiting in the wings" on the XML_Feed_Parser and Image_Barcode2 packages.
If you've had changes you've wanted to make to a PEAR package in the past but haven't ever gotten them submitted, there's not a better time than now.
