The 2.9 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Bug Fixes

• The hostname documentation link in the Management Console linked to an invalid location.
• Large Git LFS objects and release downloads were temporarily buffered to the root disk. This could lead to disk space contention.
• The create team API endpoint returned a 500 error if LDAP Sync is enabled and the team already exists.
• The hookshot-unicorn service could fail to start if there was a large backlog of webhook jobs.

Changes

• ghe-diagnostics can now upload directly to GitHub using the -u or -t [ticket reference] options.

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.
• Custom firewall rules aren't maintained during an upgrade.
• svn checkout may timeout while the repository data cache is being built. In most cases, subsequent svn checkout attempts will succeed.
• Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
• GitHub Enterprise clustering can not be configured without https.
• Deleting a search index doesn't delete all associated metadata, which are then incorrectly reused if a new search index is created. This causes search index repair jobs to be reported as finished in the site admin when they were not.
