With a bit of delay, here is an announcement of the recent TeamCity EAP build that the team published while I was spending last week of the year on a skiing holiday.
There are lots of new features both related to UI and logic. Please browse through the release notes to find those of interest to you. To get the details you are welcome to look through the fixed issues list.
We would appreciate if you try some of the features on a test installation of your server and let us know how well the features address your case and your opinion on UI changes.
If you use snapshot dependencies (which you really should for interdependent builds), try "Show changes from snapshot dependencies" option for the build configurations with dependencies.
If you have builds that need specifying additional parameters on every build run, typed parameters feature is to explore.
If you prefer to see TeamCity user names instead of VCS ones for the changes: the feature is already in.
I am sure you will find something new for you to explore in the build.
Our current plans are to polish features added in the recent EAP builds and prepare for the release of 7.0 which is planned for February. As we are approaching the release, your feedback on the features would be highly valuable at this time!
