GitHub Enterprise - The best way to build and ship software

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

Security Fixes

The followers and following count incorrectly considered suspended accounts.
Pre-receive hook's enforcement could not be updated with the API.
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.

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)

Thanks!
