Stateless GitHub App installation tokens rolled out
The brief
GitHub says its stateless installation-token rollout is complete: newly issued GitHub App tokens now default to the longer format, roughly 520 characters rather than 40. Permissions, repository access scope and the one-hour lifetime are unchanged. Integrations must accommodate longer opaque tokens. GitHub will stop honoring the temporary X-GitHub-Stateless-S2S-Token header on November 30, 2026; existing tokens remain valid until expiration.
