Release 4.3 ALPHA1
|
||||
-------------------
|
||||
|
||||
This is the first ALPHA 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 and HttpClient instances.
|
||||
|
||||
* Deprecation of preference and configuration API based on HttpParams interface in favor of
|
||||
constructor injection and plain configuration objects
|
||||
|
||||
* Reliance on object immutablity 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been replaced by immutable equivalents.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.
|
||||
|
||||
We are kindly asking all upstream projects to review API changes and help us improve
|
||||
the APIs by providing feedback and sharing ideas on dev@hc.apache.org.
|
||||
|
||||
This release also includes all fixes from the stable 4.2.x release branch.
|
||||
|
||||
Please note that new features included in this release are still considered experimental and
|
||||
their API may change in the future 4.3 releases.
