GitHub Actions is resuming enforcement of version requirements for self-hosted runners on github.com and GitHub Enterprise Cloud with Data Residency. This change is part of a broader effort to rebuild the core of GitHub Actions to increase our reliability and availability. In early 2024, the Actions team began rearchitecting the backend services that power job execution and runner communication—a foundational investment in the reliability, availability, and performance our customers depend on. The new architecture now handles over 120 million jobs per day, more than three times the volume before the migration, and enables enterprises to start seven times more jobs per minute than previously possible. Resuming version enforcement is the next step in completing this migration: as all runners move onto the new platform, older runner versions that are incompatible with the updated infrastructure can no longer be supported.
There are two requirements that together keep a runner compatible with the new platform:
To configure or (re)register a runner: The runner must be on version 2.329.0 or later. This is the minimum version required for the new architecture to recognize the runner and allow it to connect.
