What breaks

Starting September 29, 2026, version limits are enforced on self-hosted runners for GitHub Enterprise Cloud.

Runners below version 2.329.0 will be unable to register or reregister.
Runners below the (higher) minimum runtime version will stop running workflow jobs, even if already registered.
GitHub Enterprise Cloud with Data Residency is unaffected by this date shift since enforcement already began there on July 31, 2026.

What to do

Upgrade any self-hosted runners that are below the required versions before the enforcement date.

Check current runner versions against the registration and runtime minimums.
Upgrade runners below version 2.329.0 or below the runtime minimum.
Use the REST API for runner version deprecations to check dates and automate alerts for fleets nearing their deadline.
Consult the self-hosted runner documentation for upgrade guidance.
