Release 5.4 BETA1
------------------
This is the first BETA release in the 5.4 release series. It upgrades HttpCore to version
5.3-beta1 and adds a few minor improvements and fixes.
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 is 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).
* Cache control and context APIs.
* ETag APIs.
* TLS SNI and endpoint identification improvements.
* Support for RFC 2817 (Upgrading to TLS Within HTTP/1.1).
* Auth cache no longer makes use of Java serialization.
* Deprecation of ConnectionSocketFactory and LayeredConnectionSocketFactory.
* HttpContext optimization and performance improvement.
Change Log
-------------------
* HTTPCLIENT-2328: Blocking I/O connections to check if the opposite TLS endpoint
has been closed by the opposite endpoint while writing out request body.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* Redesign of test server APIs and integration test setup.
Contributed by Oleg Kalnichevski <olegk at apache.org>

Contributed by Vladimir Sitnikov <sitnikov.vladimir at gmail.com>
Release 5.4 ALPHA2
------------------
This is the second and likely the last ALPHA release in the 5.3 release series.
It finalizes the new Cache API introduced in the previous ALPHA release and also
improves TLS customization for the classic transport, SNI and endpoint identification
support, authentication data caching, and HTTP context performance. It also introduces
support for optional TLS upgrades for HTTP/1.1 connections.
Change Log
-------------------
* HttpClientContext to use instance variables for standard attributes.
Contributed by Oleg Kalnichevski <olegk at apache.org>

* RouteInfo and HttpRoute to include the target name from the URI authority in case it differs
from the target host (the host recognizes multiple authorities).
Contributed by Oleg Kalnichevski <olegk at apache.org>
* HTTPCLIENT-2316: BasicHttpClientConnectionManager incorrectly re-uses the released connection
if it has been closed out by the protocol handler.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* HTTPCLIENT-2070: Auth cache to no longer rely on Java serialization for auth state caching.
Contributed by Oleg Kalnichevski <olegk at apache.org>

Contributed by Oleg Kalnichevski <olegk at apache.org>

having been closed or discarded instead of plain IllegalStateException.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 5.4 ALPHA1

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.
