-Release 5.0-ALPHA3
+Release 5.0-BETA1
+-------------------
+
+This is the first BETA release of HttpClient 5.0. The 5.0 release serices introduces
+support for the HTTP/2 protocol and event driven messaging APIs consistent for all
+supported HTTP protocol versions.
+
+HttpClient ships with two client implementations:
+
+* HttpClient Classic is based on the classic (blocking) I/O model; largely compatible
+ with the 4.x APIs; supports HTTP/1.1 only.
+
+* HttpClient Async is based on NIO model; new event driven APIs consistent for all supported
+ HTTP protocol versions; supports both HTTP/1.1 and HTTP/2.
+
+
+Notable new features in this release:
+
+* New asynchronous HTTP cache backend APIs
+
+* Fully asynchronous HTTP cache backend based on Memcached
+
+* Support for bulk cache retrieval
+
+Notable changes and features included in the 5.0 series are:
+
+* Support for the HTTP/2 protocol and conformance to requirements and
+ recommendations of the latest HTTP/2 protocol specification documents
+ (RFC 7540, RFC 7541.)
+
+ Supported features:
+
+ ** HPACK header compression
+ ** Stream multiplexing (client and server)
+ ** Flow control
+ ** Response push
+ ** Message trailers
+ ** Expect-continue handshake
+ ** Connection validation (ping)
+ ** Application-layer protocol negotiation (ALPN) on Java 9.0.1+
+ ** TLS 1.2 security features
+
+* Improved conformance to requirements and recommendations of the latest HTTP/1.1 protocol
+ specification documents (RFC 7230, RFC 7231.)
+
+* 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.client5'.
+
+* Maven group id changed to 'org.apache.httpcomponents.client5'.
+
+HttpClient 5.0 releases can be co-located with earlier major versions on the same classpath
+due to the change in package names and Maven module coordinates.
+
+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.
+
+
