Release 5.2.4
------------------
This is a maintenance release that corrects a major defect discovered since release 5.2.3 that
can lead to an H2 connection failing at runtime with the message "Frame size exceeds maximum" when
executing requests with an enclosed message body and the remote endpoint having negotiated
a maximum frame size larger than the protocol default (16KB).
Change Log
-------------------
* HTTPCORE-762: H2 protocol handler incorrectly determines the maximum frame size for outgoing frames
in case the remote endpoint negotiated a max frame size larger than the protocol default.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 5.2.3
------------------
This is a maintenance release that corrects several defects discovered since release 5.2.2 including
a major defect that can cause non-blocking character-based consumers to enter an invalid state and
stop processing incoming data.
Change Log
-------------------
* HTTPCORE-757: AbstractCharDataConsumer fails to correctly handle incomplete UTF8 encoded data split
across multiple data packets.

** expect-continue handshake
** connection validation (ping)
** application-layer protocol negotiation (ALPN) on Java 9+
