Subject [ANNOUNCEMENT] HttpComponents Core 5.0 beta7 released
Date Mon, 04 Mar 2019 08:31:59 GMT
The Apache HttpComponents project is pleased to announce 5.0-beta7
release of HttpComponents Core. 

This BETA release adds support for SOCKS version 5, improves support
for TLS handshake timeout configuration, improves URI builder, and
fixes various defects.

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

* 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 stabilization and documentation
