What's New in This Release: [ read full changelog ]
· 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 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 Several old classes whose instances can be shared by multiple request exchanges have been replaced by immutable equivalents.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.
