TeamCity Release Cycle
The default stages of a TeamCity release:
TeamCity Cloud Major Release
This is the first official version where the new features are rolled out to. It is released approximately once in two months as
TeamCity On-Premises Major Release
A major TeamCity On-Premises version is usually released every 6-7 months. There are multiple minor (bugfix) releases following the major release. Bugfix releases and support patches for critical issues, if applicable, are provided until End of Sale of the release.
TeamCity On-Premises End of Sale
Occurs for the previous major version with the release of the next major version. After this time, no bugfix updates or patches are usually provided (except critical issues without a workaround which allow for a relatively simple fix, or make it impossible to upgrade to the next version). Only limited support is provided for a major version after its end of sale.
TeamCity On-Premises End of Support
Occurs with the release of two newer major versions. At this point, we stop providing regular technical support for the On-Premises release.
