Release 5.0.1
------------------
This release improves handling of early response messages by the classic client protocol handler
and fixes a number of minor defects.
Change Log
-------------------
* Add handling of early response messages by the classic client protocol handler.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* HTTPCORE-631: Revised i/o reactor shutdown sequence and resource de-allocation.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* Fix CharArrayBuffer.subSequence(beganIndex,endIndex) to return right result.
Contributed by Lee Ray <liruigo at gmail.com>
* Added exception callback to async server implementations enabling logging of unexpected and
fatal exceptions in the server side protocol handlers.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 5.0
------------------
This is the first stable (GA) release of HttpCore 5.0.
Notable changes and features included in the 5.0 series:
* Support for HTTP/2 protocol and conformance to requirements and recommendations
of the latest HTTP/2 protocol specification (RFC 7540, RFC 7541)
Supported features:
** HPACK header compression
** stream multiplexing (client and server)
** flow control
** response push (client and server)
** message trailers
** expect-continue handshake
** connection validation (ping)
** application-layer protocol negotiation (ALPN) on Java 9+
** TLS 1.2 security features
Features out of scope for 5.0 release:
** padding of outgoing frames
** stream priority
** plain connection HTTP/1.1 upgrade
** CONNECT method
* Improved conformance to requirements and recommendations of the latest HTTP/1.1 protocol
specification (RFC 7230, RFC 7231)
* New asynchronous HTTP transport APIs consistent for both HTTP/1.1 and HTTP/2 transport.
* Redesigned I/O reactor APIs and improved NIO based reactor implementation for a greater
performance and scalability.
* Support for server-side request filters for classic and asynchronous server implementations.
Request filters could be used to implement cross-cutting protocol aspects such
as the 'expect-continue' handshaking and user authentication / authorization.
* Support for Reactive Streams API [http://www.reactive-streams.org/]
* Redesigned connection pool implementation with strict connection limit guarantees.
The connection pool is expected to have a better performance under higher concurrency
due to reduced global pool lock contention.
* New connection pool implementation with lax connection limit guarantees and better
performance under higher concurrency due to absence of a global pool lock.
* Package name space changed to 'org.apache.hc.core5'
* Maven group id changed to 'org.apache.httpcomponents.core5'
HttpCore 5.0 releases can be co-located with earlier versions.
Change Log
-------------------
* GitHub #183: IO reactor status equality clean ups.
Contributed by Gary Gregory <garydgregory at gmail.com>
* HTTPCORE-623 GitHub #185: Change org.apache.hc.core5.http.io.BHttpConnection.isDataAvailable() int input to Timeout.
Contributed by Gary Gregory <garydgregory at gmail.com>
* GitHub #188: Add PathEntity, a Path based implementation of HttpEntity. (#188)
Contributed by Gary Gregory <garydgregory at gmail.com>
* GitHub #191: Add org.apache.hc.core5.http.Method.normalizedValueOf(String).

Release 5.0-BETA10
-------------------
This BETA fixes a number of defects found since the last release.
IMPORTANT: This release is expected to be the last BETA version. If no major
design flaws are found, the actual 5.0 API will be frozen and the next version will be
promoted to GA.
Change Log
-------------------
* HTTPCORE-608: Fixes regression that can lead to performance degradation of
asynchronous HTTP/1.1 protocol handlers.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* HTTPCORE-606: HTTP/2 protocol handler incorrectly uses larger frame size prior
to SETTING handshake completion; revision of SETTINGS handshake implementation.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* Bug fix: HTTP/2 Protocol handler does not update global connection output window
in some cases.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* Upgraded Conscrypt dependency to version 2.2.1
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 5.0-BETA9
-------------------
This BETA fixes a number of defects found since the last release, improves behavior
of the lax (concurrent) connection pools (special thanks to Linton Miller), simplifies
and improves input event handling of SSL/TLS sessions and the HTTP/1.1 protocol event
handler.
Please note that the following interfaces have marked as internal as of this release:
IOSession, IOEventHandler, IOEventHandlerFactory.
IMPORTANT: This release is expected to be the last BETA version. If no major
design flaws are found, the actual 5.0 API will be frozen and the next version will be
promoted to GA.
Change Log
-------------------
* HTTPCORE-604: async HTTP/1.1 protocol handler must close the i/o session if it cannot
be kept alive before passing control to the message exchange hanlder.

Release 5.0-BETA8
-------------------
This BETA fixes a number of defects found since the last release and adds several
convenience factory and builder classes, mainly for TLS configuration and HTTP
message construction.
As of this version all server and requester implementations exclude weak TLS protocol
versions and ciphers.
Please note that the following interfaces have changed: ResponseChannel,
AsyncRequestConsumer, AsyncResponseConsumer, HttpContentProducer, SSLServerSetupHandler.
IMPORTANT: This release is expected to be the last BETA version. If no major
design flaws are found the actual 5.0 API will be frozen and the next version will be
promoted to GA.

Release 5.0-BETA2
-------------------
This BETA release fixes a number of defects found since the previous release and
adds several incremental improvements.
Notable changes and features included in the 5.0 series:
* Support for HTTP/2 protocol and conformance to requirements and recommendations
of the latest HTTP/2 protocol specification (RFC 7540, RFC 7541)
Supported features:
** HPACK header compression
** stream multiplexing (client and server)
** flow control
** response push (client and server)
** message trailers
** expect-continue handshake
** connection validation (ping)
** application-layer protocol negotiation (ALPN) on Java 9+
** TLS 1.2 security features
Features out of scope for 5.0 release:
** padding of outgoing frames
** stream priority
** plain connection HTTP/1.1 upgrade
** CONNECT method
* Improved conformance to requirements and recommendations of the latest HTTP/1.1 protocol
specification (RFC 7230, RFC 7231)
* New asynchronous HTTP transport APIs consistent for both HTTP/1.1 and HTTP/2 transport.
* Redesigned I/O reactor APIs and improved NIO based reactor implementation for a greater
performance and scalability.
* Support for server-side request filters for classic and asynchronous server implementations.
Request filters could be used to implement cross-cutting protocol aspects such
as the 'expect-continue' handshaking and user authentication / authorization.
* Redesigned connection pool implementation with strict connection limit guarantees.
The connection pool is expected to have a better performance under higher concurrency
due to reduced global pool lock contention.
* New connection pool implementation with lax connection limit guarantees and better
performance under higher concurrency due to absence of a global pool lock.
* Package name space changed to 'org.apache.hc.core5'
* Maven group id changed to 'org.apache.httpcomponents.core5'
HttpCore 5.0 releases can be co-located with earlier versions.
The 5.0 APIs are considered feature complete and are not expected to undergo any major changes
anymore. The focus of development is now shifting to API polish, code stabilisation
and documentation improvements.
