The 2.14 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Known Issues

• 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.
• Issues cannot be closed if they contain a permalink to a blob in the same repository where the file path is longer than 255 characters.
• GitHub Enterprise incorrectly enforces a version of Backup Utilities that is the same or newer than the precise patch version of GitHub Enterprise. (updated 2019-06-25)
