Changes for 4.4-alpha1
Release 4.4 ALPHA1
-------------------
This is the first ALPHA release of HttpClient 4.4. Notable features and enhancements included
in the 4.4 branch are:
* More efficient stale connection checking: indiscriminate connection checking which results
in approximately 20 to 50 ms overhead per request has been deprecated in favor of conditional
connection state validation (persistent connections are to be re-validated only if a specified
period inactivity has elapsed)
* Native windows Negotiate/NTLM via JNA: when running on Windows OS HttpClient configured to use
native NTLM or SPNEGO authentication schemes can make use of platform specific functionality
via JNA and current user system credentials
* Authentication cache thread-safety: authentication caches used by HttpClient is now thread-safe
and can be shared by multiple threads in order to re-use authentication state for subsequent
requests
This release also includes all fixes from the stable 4.3.x release branch.
Please note that as of 4.4 HttpClient requires Java 1.6 or newer.
Please note that new features included in this release are still considered experimental and
their API may change in the future 4.4 alpha and beta releases.

Release 4.3.4
-------------------
HttpClient 4.3.4 (GA) is a maintenance release that improves performance in high concurrency
scenarios. This version replaces dynamic proxies with custom proxy classes and eliminates thread
contention in java.reflect.Proxy.newInstance() when leasing connections from the connection pool
and processing response messages.
