It's been 8 months since 9.0 release, and today is the time to share all the new features we've implemented during this period: TeamCity 9.1 release build is now available for download.
It includes lots of new features and bug fixes. There are some security-related fixes, so prompt upgrade for your servers is recommended.
If you are interested in details there is the full list of fixed issues as filed in our issue tracker. Security-related issues are not yet public, we will make them publicly visible in several weeks.
If you are using professional version or your enterprise license maintenance period has not yet elapsed: upgrade. Otherwise consider using evaluation license key available from the download page to probe the version.
