TeamCity 2026.2.2 and 2026.1.6 Updates

TeamCity On-Premises 2026.2.2 and 2026.1.6 bug-fix updates are now available. These updates resolve a significant number of issues, including security and performance issues, as well as the following bugs:

Projects created by their parent projects’ versioned settings cannot collect new changes;

Cloud agents cannot be matched to their related instances after a sever restart;

Slow revision calculation for checkout rules affecting rarely changed files;

Secondary nodes cannot retrieve the list of available security patches.

As always, we strongly recommend installing these updates, as they address security vulnerabilities and help keep your TeamCity On-Premises instance protected against potential threats.

See TeamCity 2026.1.6 Release Notes and TeamCity 2026.2.2 Release Notes for the complete list of resolved issues.
