The 2.3 series release notes contain important changes in this release series.
- MEDIUM Release assets could be accessed by unauthenticated users in private mode.
- Packages have been updated to the latest security versions.
- We incorrectly redirect to the dashboard if you accessed GitHub Enterprise using an alias while in private mode. This might happen if you set a fully qualified domain name but the subdomain resolves correctly.
- Email can't be sent over TLS when SSL is disabled.
- Deleting a user doesn't delete their gists, which can cause problems with replication.
- Images uploaded to issues save with an absolute URL, so they can be broken if the hostname changes.
- On a freshly set up GitHub Enterprise without any users, an attacker could create the first admin user.
- The management console settings interface doesn't clearly show if you have previously uploaded certificate files or a private key.
- Management console sessions can expire too quickly for Safari users.
- Gist repositories are not garbage collected by the maintenance scheduler.
- Custom firewall rules aren't maintained during an upgrade.
- Repositories that are in an incomplete state, which is a rare problem, can cause the migration to the new repository disk layout to fail.
- Enqueued background jobs are sometimes not purged when a repository is deleted.
- When a fork is detached from its repository network by an administrator or by changing visibility, its filesystem path won't be updated on a high availability replica until at least one commit has been pushed.
- Viewing raw files in repositories owned by a user or organization named "github" fails with a 400 error.
