HttpClient 4.5 (GA) is a minor feature release that includes several incremental enhancements to the exisitng functionality such as support for private domains in the Mozilla Public Suffix List.

HttpClient 4.4.1 (GA) is a maintenance release that fixes a number of defects in new functionality introduced in version 4.4.

Users of HttpClient 4.4 are encouraged to upgrade.

Please note that as of 4.4 HttpClient requires Java 1.6 or newer.

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.
