On the Zend Developer Zone there's a new post announcing the latest Bug Hunt Days for the Zend Framework happening this week - Thursday, July 15th through Sunday, July 19th.
For those of you unfamiliar with the event, each month, we organize the community to help reduce the number of open issues reported against the framework. The last two months of bug hunts collectively closed 63 issues. The May bug hunt saw new first-time winner Jan Pieper step up and take first. Then in June, Christian Albrecht (a previous bug hunt winner) took home first again. Congratulations Jan & Christian and thanks for making the bug hunt for May and June a success.
If you'd like to get involved, you'll need to have a CLA with Zend approved and ready to go. Then just show up on the #zftalk.dev channel on the Freenode IRC network and jump right in. There's also a guide to help you get started as well.
