GitHub Enterprise - The best way to build and ship software

The 2.19 series release notes contain important changes in this release series.

Security Fixes

HIGH: OpenSSL has been updated to address CVE-2020-1967.
HIGH: Git has been updated to address CVE-2020-5260 and CVE-2020-11008. New restrictions prevent malicious repositories from being pushed to the server instance, protecting clients which have not yet been patched.
LOW: ImageMagick has been updated to address CVE-2019-10131.
Packages have been updated to the latest security versions.

A mismatch in MySQL configurations could cause backups to fail in large installations.
A periodic task to clean up old log files would fail and send error messages to the local root account.
When a GitHub Enterprise Server license contained non-ASCII characters, a GET request to the Management Console API /setup/api/settings endpoint would result in an Internal Server Error.
The recovery console would prompt for a root password, even if the root account was locked.
When using the GraphQL's API for filtering issues assigned to a non-existent user, the message received would not be descriptive enough.
A CODEOWNERS file with a leading UTF-8 Byte Order Mark would cause all codeowner rules to be ignored.

When an external identity provider controlled user's site administrator status, users could not be demoted via the command line utility.

On a freshly set up GitHub Enterprise Server without any users, an attacker could create the first admin user.
Custom firewall rules are not maintained during an upgrade.
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.
When pushing to a gist, an exception could be triggered during the post-receive hook.
When "Users can search GitHub.com" is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.
Security alerts are not reported when pushing to a repository on the command line. (updated 2020-06-23)
