package httpcats

v0.3.0 (2026-05-06) Paris - France

• Don't predate how we close underlying connection when we write something. It avoid a "double-close" (@dinosaure, #49)
• breaking change Be able to specify a UNIX domain socket for listening (@theAlexes, #51)
• Delete the rresult dependency on tests (@dinosaure, #54)
• Close only when (httpcats) we create and bind a socket (and don't do that when the user pass a socket for us) (@theAlexes, @dinosaure, #53, #57)

• Clean and fix our runtime (@dinosaure, #59, #61)

  Here we decided to trust the underlying state machine H{1,2}.{Server,Client}_connection.t to properly close a connection. When we close it, we Miou.cancel tasks (instead of Miou.await them). httpcats requires miou.0.6.0 (which provides Miou.take). When the Flow raises an exception, we report this exception to the state machine & it should stop everything.

• breaking change Pass the conn value to the handler (@dinosaure, #60)

v0.2.1 (2026-03-25) Paris - France

• Use Miou.Ownership to release correctly our resource in any cases (including the cancellation case) (@dinosaure, #47)
• Replace assert false by failwith (@dinosaure, #47)

• Improve performances (@dinosaure, #46) We use a pre-allocated buffer to read/write things into the given flow now We don't try to split bigarray to small strings We fixed a bit the way to stop a server

  A benchmark was made with wrk and compare httpcats, httpun+eio, vif and nginx. It is available here: https://robur-coop.github.io/httpcats/ The protocol of the benchmark is described into our file bench/PROTOCOL.md. The collected results from our machine is available into our file bench/BENCH.md. Implementations are available into the bench/ folder.
