3 + ## v0.23.0 (2026-06-17)
4 +
5 + ### Fixed
6 +
7 + - Reject `http` and `https` request and pool URLs without hosts before attempting requests #371, fixes #186
8 + - Drop `:certs_keys`, `:certfile`, and `:keyfile` from TCP transport options for HTTP requests to avoid `:badarg` errors #377
9 + - Fix a race condition when dynamically starting pool supervisors that could return `:pool_not_available` while workers were still registering #379
10 + - Make the HTTP/2 ALPN negotiation failure assertion compatible with OTP 29 TLS alert capitalization #378
11 +
12 + ### Other
13 +
14 + - Update development and test dependencies, including Mint 1.9 #378
15 + - CI: update to Elixir 1.20.1 and Erlang/OTP 29.0.2 and fix Credo issues #378
