The 2.10 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Bug Fixes

• The followers and following count incorrectly considered suspended accounts.
• After changing the visibility of a repository, wiki search results have a conflicting number of displayed search results. Administrators can reindex the wiki through the site admin dashboard.
• Pre-receive hook's enforcement could not be updated with the API.
• When restoring a deleted repository via the site admin dashboard, an error message could be shown even though the restore worked.
• Updates to a pull request through the API could incorrectly modify manitainer_can_modify to false when the field was not a part of the request.

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.
• NUMA enabled appliances can crash with a kernel panic. This is a known issue with linux-image-3.16.51-2 and the workaround is to add the numa=off parameter to the kernel command line in /boot/grub/grub.cfg. Please contact GitHub Enterprise Support if you have questions. (updated 2017-12-28)
• The create team API endpoint returns a 500 error if LDAP Sync is enabled and the team already exists. (updated 2018-01-09)
• Pull request reviewer usernames were not updated if a reviewer was mapped to a different username when migrating repositories using ghe-migrator. (updated 2018-04-12)
