Cowboy 2.1

09 Nov

Cowboy 2.1.0 has been released!

This release focused on adding features that were temporarily removed during the 2.0 release process:

  • The client TLS certificate can now be obtained.

  • The 100 Continue response is now sent automatically again when necessary.

  • NEW: It is now possible to send informational responses (1XX) directly from user code via the cowboy_req:inform/2,3 functions.

  • NEW: cowboy_rest handlers can now switch to any other type of handler from almost any callback. This is especially useful to switch to cowboy_loop to stream the request or response body.

A number of bugs have also been fixed. A more complete list of changes can be found in the migration guide: Migrating from Cowboy 2.0 to 2.1.

The next release will see the added support for trailers, which are necessary for implementing the gRPC protocol.

You can donate to this project via BountySource because I need to eat snacks when I write code. Thanks in advance!

As usual, any feedback is appreciated, and any issues should be reported by opening a ticket. Thanks!
