Release notes for GitHub Enterprise Server versions 2.20.0+ have moved to GitHub Docs. Release notes for versions prior to 2.20.0 will remain on GitHub Enterprise Releases
Packages have been updated to the latest security versions.
Bug Fixes
Release assets uploaded via the Releases API would fail if the asset is larger than 1GB.
The package validation performed when upgrading would print the result of an internal check.
The maximum number of allowed connections to the internal HAProxy load balancer could be reached on very large instances leading to a large backlog of resqued jobs.
DNS resolution of appliance hostnames in a HA configuration could timeout or return an incorrect IP address.
Some pull requests and issues were purged completely when restoring the repository right after deleting it.
Changes
Running ghe-repl-promote will now prompt for confirmation. To promote a replica without confirmation, use the -y flag: ghe-repl-promote -y.
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.
