So here it comes: the final TeamCity 8.1 with loads of new features, many fixes and performance improvements is ready for your production TeamCity servers.
Here you will find much simplified setup which includes creating projects from a single VCS URL, auto-discovery of the build steps and other suggested settings. Sure you will have great ideas on adding more "magic" to the configuration process - make sure to let us know your suggestions.
Automatic Merge for Git and Mercurial (a peer to pre-tested commit for non-DVCS) will prove useful for your DVCS needs.
Read through the complete list of the features added and get ready for the upgrade!
This version does change the data format, so make sure you create a backup before upgrading.
Let it build!
