This is the first EAP of the TeamCity 5.0 (code name Darjeeling).
Issues are now first class citizens in TeamCity. Out of the box TeamCity integrates with Jira, Bugzilla and Jetbrains own tracker Charisma. Plugins can be written to support other trackers. There is also Open API for working with issues.
Issue tracker integration is configured on a separate tab of the Server configuration page:
After that TeamCity will start recognizing issue ids mentioned in the change or build comments and associates issues with builds. You can see change details by moving your mouse over issue id:
If build contains changes with issues mentioned in them, then new tab will appear where build related issues are shown:
Note that the issue is considered resolved in a build if the build includes the last change, in which this issue is mentioned.
There is also Issue Log page made similar to Changes Log. It shows issues detected by TeamCity optionally grouped by builds:
You can now easily archive no longer active projects. Archived projects will be shown on the separate tab in the Administration area, their build configurations will be paused and changes collecting for their VCS roots will be stopped (if VCS roots are not shared with active projects). Builds however can be triggered manually, and project/build configuration settings can be edited.
