As previously announced, the format of GitHub authentication tokens has changed. The following token types have been affected:
- Personal access tokens
- OAuth Access Tokens
- GitHub App user-to-server tokens
- GitHub App server-to-server tokens
- Refresh tokens
Due to the updated format of GitHub authentication tokens, GitHub Connect will no longer support instances running GitHub Enterprise Server (GHES) 3.1 or older after June 3, 2022. To continue using GitHub Connect, an upgrade to GHES 3.2 or newer will be required by June 3. GitHub Connect is necessary in order to use the latest features, such as Dependabot updates, license sync, GitHub.com Actions synchronization, and unified contributions.
