Feb 1, 2026

February 2026 monthly summary for canonical/mir: Key accomplishments include CI pipeline reliability improvements and a critical TICS concurrency bug fix. By removing the GPU graphics hardware dependency for performance tests, CI runs become stable in headless environments, reducing flaky results and speeding feedback. The TICS workflow concurrency rules were updated to prevent QServer interruptions that could corrupt the TICS database, safeguarding data integrity. Together, these changes reduce risk in release pipelines, shorten cycle times, and demonstrate strong CI/CD discipline and robust workflow governance.
