[ANNOUNCEMENT] HttpComponents Core 5.0 alpha4 released

[Oleg Kalnichevski]

The Apache HttpComponents project is pleased to announce 5.0-alpha4
release of HttpComponents Core. 

This is a major release that renders HttpCore API incompatible with the
stable 4.x branch and upgrades HTTP/1.1 and HTTP/2 protocol conformance
to the requirements and recommendations of the latest protocol
specification.

Notable changes and features included in the 5.0 series are:

* 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 1.9+
** 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.

This release is expected to be the last ALPHA release in the 5.0
series.

Please note that at this point 5.0 APIs are considered unstable and may
change in the coming releases without providing a migration path

!!!IMPORTANT!!! 
We have been considering upgrading minimal JRE level to 1.8 for all
HttpCore 5.x artifacts. If you would like HttpCore to remain 1.7
compatible please do let us know by posting a message to dev@hc.apache.
