The Apache HttpComponents project is pleased to announce 5.4-alpha1 release of HttpComponents HttpClient.
This is the first ALPHA release in the 5.4 release series that improves HTTP protocol support by ensuring conformance to the latest HTTP specification (RFC 9110, RFC 9111, RFC 7616, RFC 7617), ensures compatibility with Java Virtual Threads by replacing 'synchronized' keywords in critical sections with Java lock primitives. The HTTP caching protocol layer has also been redesigned and overhauled to improve cache efficiency and optimize performance. IMPORTANT! Please note the new cache entry serialization format is incompatible with earlier versions of HttpClient Cache. Persistent caches (file system based, Memcached, EhCAche with object serialization) created with any earlier version MUST be flushed and re- populated or the cache backend MUST be configured to use the old deprecated cache entry serializer. Notable changes and features included in the 5.4 series: * Improved conformance to RFC 9110 (HTTP Semantics), RFC 7616 (HTTP Digest Access Authentication), RFC 2617 (’Basic’ HTTP Authentication Scheme). * UTF-8 encoding to be used by default for text where appropriate. * Compatibility with Java Virtual Threads and Java 21 Runtime. * Redesign and rewrite of the HTTP caching protocol layer for better efficiency and improved conformance to RFC 9111 (HTTP Caching).

Web services, network-enabled appliances and the growth of network computing continue to expand the role of the HTTP protocol beyond user-driven web browsers, while increasing the number of applications that require HTTP support. Designed for extension while providing robust support for the base HTTP protocol, HttpClient may be of interest to anyone building HTTP-aware client applications such as web browsers, web service clients, or systems that leverage or extend the HTTP protocol for distributed communication. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@hc.apache.org For additional commands, e-mail: dev-h...@hc.apache.org
