TeamCity 2026.1.1, the first bug-fix release for TeamCity On-Premises 2026.1 servers, resolves over 20 issues, including problems with build agent IP addresses, a damaged Rake plugin, and failing uploads to S3 buckets. This update enhances performance, compatibility, stability, and security, and it allows for easy upgrades or downgrades within the 2026.1.x series without requiring backup or restoration. Users can update using the automatic update feature, downloading from the JetBrains website, or pulling the updated Docker image.
