Cowboy 2.9

2021 12 May

Cowboy 2.9.0 has been released!

Cowboy 2.9 implements graceful shutdown of connection processes for both HTTP/1.1 and HTTP/2 connections.

Cowboy 2.9 is the first release to support the much awaited Erlang/OTP 24 out of the box. While users that were using Ranch 2.0 already were ready for OTP 24, the Ranch version used by Cowboy out of the box was not compatible and had to be updated.

Cowboy 2.9 requires Erlang/OTP 22.0 or greater. It is tested and supported on Linux, FreeBSD, macOS and Windows.

A complete list of changes can be found in the migration guide: Migrating from Cowboy 2.8 to 2.9.
