3.21.3 (2026-11-09)
Fixed
- Handle early responses that close a WASI HTTP 0.2 request body during upload, instead of raising a connection error before reading the response.
- Release host-pool ownership after failed requests and request setup errors, preventing pool exhaustion and retention of finished asynchronous tasks. (#488)
- Windows proxy exclusions now match entire hostnames, preventing unintended proxy bypass for names such as
example.com.evil.testwhenexample.comis excluded. - Extension schemes of up to 11 characters, including
sse+nativeandpsse+native, are no longer treated as relative paths when abase_urlis set. (#468) - Query
paramsare applied to implementation-suffixed schemes such assse+nativeandwss+fast, the same way they are forsseandwss. (#469)
