The second alpha of Mantis 1.0, a free-as-in-speech (GPL) bug tracking system based on PHP and MySQL, has been posted.
Websina has released BugZero 4.0.1, a $1299 payware (+$300 for maintenance) Web-based bug tracking system that supports multiple projects, group-based access, automatic bug assignment, file attachment, email notification, and metric reports. Bug Zero is written in Java and can run on top of various backend databases including MySQL. 4.0.1 fixes bugs and adds a copy-to-create button that populates the new issue form with the values of the existing issue.
