Changes since 4.4
-------------------
* [HTTPCLIENT-1609] Stale connection check in PoolingHttpClientConnectionManager has no effect.
Internal connection pool does not correctly implement connection validation.
Contributed by Charles Lip <rene1 at singnet.com.sg>
Release 4.4 Final
-------------------
This is the first stable (GA) release of HttpClient 4.4. Notable features and enhancements included
in 4.4 series are:
* Support for the latest HTTP state management specification (RFC 6265). Please note that the old
cookie policy is still used by default for compatibility reasons. RFC 6265 compliant cookie
policies need to be explicitly configured by the user. Please also note that as of next feature
release support for Netscape draft, RFC 2109 and RFC 2965 cookie policies will be deprecated
and disabled by default. It is recommended to use RFC 6265 compliant policies for new applications
unless compatibility with RFC 2109 and RFC 2965 is required and to migrate existing applications
to the default cookie policy.
* Enhanced, redesigned and rewritten default SSL hostname verifier with improved RFC 2818
compliance
* Default SSL hostname verifier and default cookie policy now validate certificate identity
and cookie domain of origin against the public suffix list maintained by Mozilla.org
<https://publicsuffix.org/list>
* 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)
* Authentication cache thread-safety: authentication cache used by HttpClient is now thread-safe
and can be shared by multiple threads in order to re-use authentication state for subsequent
requests
* Native Windows Negotiate and NTLM via SSPI through 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 credentials. This functionality is still considered
experimental, known to have compatibility issues and subject to change without prior notice.
Use at your discretion.
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.

Release 4.3 Final
-------------------
This is the first stable (GA) release of HttpClient 4.3. The most notable enhancements included
in this release are:
* Support for Java 7 try-with-resources for resource management (connection release.)
* Added fluent Builder classes for HttpEntity, HttpRequest, HttpClient and SSLContext instances.
* Deprecation of preference and configuration API based on HttpParams interface in favor of
constructor injection and plain configuration objects.
* Reliance on object immutability instead of access synchronization for thread safety.
Several old classes whose instances can be shared by multiple request exchanges have
been replaced by immutable equivalents.
* DefaultHttpClient, DecompressingHttpClient, CachingHttpClient and similar classes are
deprecated in favor of builder classes that produce immutable HttpClient instances.
* HttpClient builders now dynamically construct a request execution pipeline tailored
specifically to the user configuration by physically excluding unnecessary protocol components.
* There is now an option to construct a minimal HttpClient implementation that can only execute
basic HTTP message exchanges without redirects, authentication, state management or proxy support.
This feature might be of particular use in web crawler development.
* There is now option to avoid strict URI syntax for request URIs by executing HTTP requests
with an explicitly specified target host. HttpClient will no longer attempt to parse the request
URI if it does not need to extract the target host from it.
This release also includes all fixes from the stable 4.2.x release branch.

Release 4.2
-------------------
This is the first stable (GA) release of HttpClient 4.2. The most notable enhancements included
in this release are:
* New facade API for HttpClient based on the concept of a fluent interface. The fluent API exposes
only the most fundamental functions of HttpClient and is intended for relatively simple use cases
that do not require the full flexibility of HttpClient. However, the fluent API almost fully
relieves the users from having to deal with connection management and resource deallocation.
* Redesigned and rewritten connection management code.
* Enhanced HTTP authentication API that enables HttpClient to handle more complex authentication
scenarios. HttpClient 4.2 is now capable of making use of multiple authentication challenges
and retry authentication with a fall-back scheme in case the primary one fails. This can be
important for compatibility with Microsoft products that are often configured to use
SPNEGO/Kerberos as the preferred authentication scheme.
Changelog

* [HTTPCLIENT-1187] If a revalidation response is deemed too old CachingHttpClient fails to
consume its content resulting in a connection leak.
