GitHub Enterprise - The best way to build and ship software

GitHub Enterprise 2.6.20 April 18, 2017 Series notes · Download

The 2.6 series release notes contain important changes in this release series.

Security Fixes

MEDIUM: Local privileged MySQL credentials and Alambic HMAC/API keys were exposed in log files included in the support bundle.
None of the currently supported releases of GitHub Enterprise are affected by the Linux kernel UDP remote code execution vulnerability issued 4 April 2017 (CVE-2016-10229).
Packages have been updated to the latest security versions.

Bug Fixes

An issue or pull request comment containing the string "User-Agent: GitHub-Hookshot" incorrectly triggered a firewall rule that caused an internal server error on several pages, including the author's profile page.
Collectd statistics were collected for the temporary pre-receive hook environment mount points.

Changes

More colors are used in the monitoring graphs in a high availability environment, making them more legible.

Deprecation of GitHub Enterprise 2.6

GitHub Enterprise 2.6 is now deprecated as of April 26, 2017. That means that no patch releases will be made, even for critical security issues, after this date. For better performance, improved security, and new features, upgrade to the newest version of GitHub Enterprise as soon as possible.

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.
Enqueued background jobs are sometimes not purged when a repository is deleted.
On instances upgraded from 2.3 and earlier, restoring a protected branch archived whilst running 2.3, will not restore all the settings correctly. This does not affect new instances or protected branches archived on later releases.
Editing custom messages in the Admin Center doesn't provide emoji suggestions.
Native emoji are lost when saving custom messages in the Admin Center.
Repository push logs don't record whether a push was forced.
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.
Uploading PNG images with through the web interface can fail with the error 'Something went really wrong, and we can't process that file.'
GitHub Enterprise clustering can not be configured without https.
Console text is difficult to read on OpenStack KVM.
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.

Thanks!
