You can now easily archive no longer active projects.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.
Separate permission controls access to this function. By default this permission is available to project administrators.

Tail mode was added to build log. Also for the running build "All messages" now updates incrementally. Scroll to the end of the "All messages" page and TeamCity will preserve scroll position.

Various improvements in Eclipse and Visual Studio plugins
Different syntax highlighting engine for web diffs
Older engine was based on native code and as such had some problems. Not all platforms were supported and random crashes were observed. Now TeamCity uses Java based syntax highlighter.
