2.2.0 has been released!
This release focused on adding features required for writing gRPC servers and on completing test suites for the core HTTP RFCs.
cowboy_req:stream_trailers/2function has been added. It terminates the streamed response by adding some trailer field values. This feature is required for gRPC.
max_skip_body_lengthoption was added. It controls how much of the request body we are willing to skip to get to the next request for HTTP/1.1 keep-alive connections.
- The CONNECT and TRACE methods have been disabled entirely. They are currently not implemented and their behavior is very specific (unlike most other methods) so it is safer to prevent their use.
Many bugs have also been fixed. A more complete list of changes can be found in the migration guide: Migrating from Cowboy 2.1 to 2.2.
The next two releases will tentatively focus on improving the support for cookies and CORS, but I'm open to suggestions. If there is a pain point in Cowboy 2.2 I would love to hear about it.
You can donate to this project via GitHub Sponsors 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!
