The 2.4 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Changes

• GitHub Enterprise is now available in the US East (Ohio) AWS region.

Known Issues

• 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.
• Custom firewall rules aren't maintained during an upgrade.
• Enqueued background jobs are sometimes not purged when a repository is deleted.
• Trying to add a file to a repository with Subversion 1.9 clients incorrectly detects the file already exists and fails.
• On instances upgraded from 2.3 and earlier, restoring an archived protected branch will not restore all the settings correctly. This does not affect new instances.

Thanks!
