GitHub Enterprise Cloud enforces the self-hosted runner minimum today, 29 September

GitHub moved the date forward in a changelog posted on 28 September.⁴ Runners below 2.329.0 cannot register or re-register. Runners below the higher minimum for running jobs stop picking up jobs, even when already registered. The change covers Enterprise Cloud only. Enterprise Server is unaffected, and Data Residency tenants have been enforced since 31 July.⁴

Relevant to: Teams that run coding agents or CI on self-hosted runners with pinned images. Check runner versions this morning; the new runner-deprecation REST API returns the cut-off dates for each version.
