    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

    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.

*  31 October 2013 - HttpComponents HttpAsyncClient 4.0 (GA) released

    This is the first stable (GA) release of Apache HttpAsyncClient 4.0. HttpAsyncClient is 
    a library for asynchronous client-side HTTP communication built on top of HttpCore NIO 
    transport. It is a complementary library to Apache HttpClient intended and optimized for 
    special cases whereby ability to scale to many thousands of concurrent connections is more 
    important than performance in terms of raw data throughput. 

    HttpAsyncClient 4.0 is designed to have similar APIs as Apache HttpClient 4.3 and a comparable
    feature set. In addition HttpAsyncClient provides full support for zero-copy file upload and 
    download operations. It presently does not support transparent content decompression and 
    automatic I/O error recovery. These features may be added in future releases.

*  7 October 2013 - HttpComponents HttpClient 4.3.1 (GA) released

*  12 September 2013 - HttpComponents HttpClient 4.3 (GA) released

    This is the first stable (GA) release of HttpClient 4.3. The 4.3 branch enhances HttpClient 
    in several key areas and includes several notable features and improvements: 

    * 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.

*  12 September 2013 - HttpComponents HttpClient 4.2.6 (GA) released

    This is a maintenance release that addresses a number of non-critical issues reported

* 22 May 2012 - HttpComponents HttpClient 4.2 (GA) released

    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. 

* 5 May 2012 - HttpComponents HttpCore 4.2 (GA) released

    This is the first stable (GA) release of HttpCore 4.2. The most notable features included in 
    this release are connection pool components for blocking and non-blocking HTTP connections and 
    new asynchronous client and server side protocol handlers.

    New protocol handling API used in conjunction with connection pooling components is expected to 
    make development of asynchronous HTTP client agents and HTTP proxies easier and less error 
    prone.

    Connection pool components are based on mature code migrated from HttpClient and HttpAsyncClient 
    modules but have a slightly different API that makes a better use of Java standard concurrent 
    primitives. 

* 22 February 2012 - HttpComponents HttpAsyncClient 4.0-beta1 released

    This the first BETA release of HttpAsyncClient. This release completes the application 
    programming interface and the feature set of HttpAsyncClient and upgrades to the latest

    This is the third ALPHA release of HttpAsyncClient 4.0. This release largely completes 
    the application programming interface and feature set of HttpAsyncClient. While the API may 
    still change in the course of the ALPHA development phase, this is expected to be the last 
    round of major API changes and the API is expected to be reasonably stable as of this release.

* 23 September 2011 - HttpComponents HttpCore 4.2-alpha2 released

    This is the second ALPHA release of HttpCore 4.2. This release comes with completely redesigned 
    and rewritten asynchronous protocol handlers. New protocol handling API used in conjunction

    The first BETA brings yet another round of API enhancements and 
    improvements in the area of connection management. Among the most notable
    ones is the capability to handle stateful connections such as persistent 
    NTLM connections and private key authenticated SSL connections.

    This is the first API stable release of HttpClient 4.0. All further 
    releases in the 4.0 code line will maintain API compatibility with this
    release.

* 22 June 2008 - HttpComponents HttpCore 4.0-beta2 released

* 26 February 2008 - HttpComponents HttpClient 4.0-alpha3 released 

    The third ALPHA release brings another round of API refinements and improvements 
    in functionality. As of this release HttpClient requires Java 5 compatible 
    runtime environment and takes full advantage of generics and new concurrency
    primitives.     

    This release also introduces new default cookie policy that selects a cookie 
    specification depending on the format of cookies sent by the target host. 
    It is no longer necessary to know beforehand what kind of HTTP cookie support 
    the target host provides. HttpClient is now able to pick up either a lenient 
    or a strict cookie policy depending on the compliance level of the target host.

    Another notable improvement is a completely reworked support for multipart 
    entities based on Apache mime4j library.

* 24 January 2008 - HttpComponents HttpCore 4.0-beta1 released 

    The first BETA version of HttpComponents Core has been released. This release 
    can be considered a major milestone, as it marks the end of API instability 
    in HttpCore. As of this release the API compatibility between minor releases
    in 4.x codeline will be maintained.

    This release includes several major improvements such as enhanced HTTP message 
    parsing API and optimized parser implementations, Java 5.0 compatibility
    for HttpCore NIO extensions.

    The focus of the development efforts will be gradually shifting towards
    providing better test coverage, documentation and performance optimizations.

    possible to send and receive SIP messages with HttpComponents Core.

* 20 July 2007 - HttpComponents HttpClient 4.0-alpha1 released 

    This release represents a complete, ground-up redesign and almost a complete rewrite of the old 
    HttpClient 3.x codeline. This release finally addresses several design flaws that existed since 
    the 1.0 release and could not be fixed without a major code overhaul and breaking API 
    compatibility.

    * Redesign of the HttpClient internals addressing all known major architectural shortcomings of 
    the 3.x codeline  

    * Cleaner, more flexible and expressive API
