The 2.11 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Bug Fixes

• A configuration run could fail in high availability environments if Redis isn't ready.
• The open-vm-tools package, included in ESXi VM images, has been updated to 2.10.1.5 to address stability issues when performing snapshots.
• The audit log migration process could leave old indices in place which would prevent upgrading to 2.11.
• LDAP team sync could cause a noticeable increase in CPU usage when synchronizing large teams.
• Pull request comments were not exported with ghe-migrator if the repository is locked.

Changes

• GraphQL authenticated requests rate limit has been increased from 200 to 5,000.

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.
• Changing the parent of a nested team can result in the nested team not receiving updated inherited permissions.
• After changing HTTP proxy configuration in the Management Console, webhooks do not use the settings unless hookshot-resqued is restarted manually via SSH by running: sudo systemctl restart hookshot-resqued. (updated 2017-12-19)
• 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. (updated 2017-12-19)
• The merge button could get stuck in the "Checking for ability to merge" state. (updated 2017-12-20)
• Rebuilding a search index—including during an upgrade to this version—could cause many exceptions to be logged to /var/log/github/exceptions.log. The fast growth of this log file could cause the root disk to fill up. (updated 2017-12-20)
• Pull request review comments migrated with ghe-migrator are displayed in the wrong order. (updated 2017-12-20)
• The pull request review request has users reversed, after migration with ghe-migrator. (updated 2017-12-20)
• The comment count in the "Conversation" tab of a pull request migrated with ghe-migrator can be wrong. (updated 2017-12-20)
• The create team API endpoint returns a 500 error if LDAP Sync is enabled and the team already exists. (updated 2018-01-09)
• The gpgverify service may consume large amounts of CPU time even when not processing requests. (updated 2018-02-14)
• 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)
• Nameid-format matching on SAML response is too strict when value is "unspecified", which can cause an error with the "Another user already owns the account." message if the IdP changes NameID. (updated 2018-06-25)

Thanks!
