Cowboy 2.18.0, Cowlib 2.19.0, Gun 2.5.0 and Ranch 2.2.1 have been released.

They contain a number of defense-in-depth and security hardening improvements so all users are encouraged to upgrade.

The security checklist has received a few tweaks as well.

Expect a few more security oriented releases in the near future. They will address increased threats from AI agents usage. Please refer to the companion post explaining the security strategy for more details.

A detailed list of changes can be found in the Cowboy migration guide, the Gun migration guide and the Ranch migration guide.
