Eventum is a user-friendly and flexible issue tracking system that can be used by a support department to track incoming technical support requests, or by a software development team to quickly organize tasks and bugs. Eventum is used by the MySQL AB Technical Support team, and has allowed us to dramatically improve our response times.
Scmbug integrates software configuration management (SCM) with bug-tracking. It aims to solve the integration problem once and for all. It will glue any source code version control system (such as CVS/CVSNT, Subversion, and Git) with any bug tracking system (such as Bugzilla, Mantis, Request Tracker, Test Director).
