Cowboy 2.8

2020 26 May

Cowboy 2.8.0 has been released!

Cowboy 2.8 contains many optimizations for all protocols. HTTP/1.1 has received the largest improvements and Cowboy will now be able to handle noticeably more requests. Thanks to the folks at Stressgrid for helping identify that the performance was lower than it should have been and for benchmarking my many changes and experiments.

Cowboy 2.8 also contains a small number of tweaks and bug fixes. Cowboy 2.8 is the first Cowboy release, ever, to be consistently green on all tested platforms. This is mostly due to the reworking of some test cases, but a few bugs were discovered and fixed in the process.

Cowboy 2.8 requires Erlang/OTP 22.0 or greater. It may also work out of the box with Erlang/OTP 21.3 but this was not tested and is not supported. 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 2.7 to 2.8.

I have free time available for consulting or for paid open source development at the moment. If you are interested, drop me an email at [email protected]. I have gathered that there's interest in a pure Erlang GRPC implementation, and there's also QUIC and HTTP/3 that will be ready soon, for examples of projects I'd be interested in working on.

You can donate to this project via GitHub Sponsors. These funds are used to pay for additional servers for testing. Corporate sponsorship options are also available, please contact me directly!

As usual, feedback is appreciated, and issues or questions should be sent via Github tickets. Thanks!
