This is the final planned release in the 0.21 series. Bugfixes and community submissions will be considered for discretionary releases, but the development team will now focus on later branches.

http4s-blaze-client

Bugfixes

#4810: Read from idle blaze-client connections to prevent retaining (and trying to use) half-closed connections.
#4812: Remove request retry on EOF from blaze-client. This could theoretically resubmit non-idempotent requests. The problem the retry attempted to solve is mitigated by #4810.
#4815: Fix "IdleTimeoutStage isn't connected" errors by waiting for the final write to finish before returning the connection to the pool.

http4s-blaze-core

Bugfixes

#4796: Reset the idle timeout after readRequest completes, not when it's called. Affects both blaze-server and blaze-client.

http4s-blaze-server

Bugfixes

#4753: Distinguish between reserved and unknown websocket frame opcodes. Resolves a MatchError.
#4792: Fixes HTTP/2 connections on modern JDKs by replacing legacy ALPN libraries.
#4796: Reset idle timeout when readRequest completes, not when it's called.

Enhancements

#4761: Use the TickWheelExecutor to schedule timeouts with less locking. Change how the parser is acquired to reduce lock contention in Http1ServerStage. Significant increases in throughput are observed on small requests with many cores.

http4s-circe

Enhancements

#4736: Add streamJsonArrayDecoder

http4s-ember-core

Enhancements

#4735: Simplify message parsing by parsing everything up to the \r\n in one pass. The max header size and max prelude size settings should keep memory consumption limited.

http4s-ember-server

Bugfixes

#4750: Drain the socket's read buffer only after the response is written to the socket. Resolves several flavors of network error.
#4823: Implement persistent connection logic for HTTP/1.0 requests.

http4s-jetty

Bugfixes

#4783: Fix bug with shared ThreadPool being destroyed. Prefer a Resource[F, ThreadPool] whose lifecycle shares Jetty's. For compatibility, prevent the default from being destroyed.

http4s-server

Enhancements

#4793: Make use of IPv4 vs. IPv6 as default address explicit. Applies to all backends.
