Build 10669 is going to get somewhat more attention then its siblings. It just have been announced as official TeamCity 5.0 release build.
A year after 4.0 and about 7 months after 4.5, we are releasing version 5.0.
Many improvements and fixes throughout entire system: from agents to server, from deep internals to Web UI.
Some of the largest additions feature Amazon EC2 support, improved Maven experience, issue trackers integration, creating backup from UI and build configuration templates.
Upgrade is not free, but all existing customers can upgrade for 50% of the full price. See details on the official site.
