The 2.4 series release notes contain important changes in this release series.
- Running the
ghe-diagnostics command line utility would report a harmless permission denied error.
- The 'Enable sign-up' option was displayed in the Management Console when external authentication was configured. Account creation is controlled by your external authentication, so the setting had no effect.
- Old builds of GitHub Pages sites weren't garbage collected, so they could build up and waste disk space.
- An administrative SSH key was accidentally created and added to the Management Console.
- Alambic and Pages high availability replication reported 'UNKNOWN' status for delays less than 30 seconds.
- High availability replication sometimes failed to set the correct master identifier during an upgrade. This prevented MySQL replication from starting.
- Restoring backups taken from previous versions to GitHub Enterprise 2.4 would fail.
- Deleting an impersonation OAuth token via the API would fail.
- An Organization's event log now reports changes to the default permissions and who made the changes.
- 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.
- 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.
- Custom firewall rules aren't maintained during an upgrade.
- Enqueued background jobs are sometimes not purged when a repository is deleted.
- Viewing raw files in repositories owned by a user or organization named "github" fails with a 400 error. (updated 2015-12-15)
- Trying to add a file to a repository with Subversion 1.9 clients incorrectly detects the file already exists and fails. (updated 2016-01-14)
