Changes since 4.1.2
Release 4.2 ALPHA1
-------------------
This is the first ALPHA release of HttpClient 4.2. The 4.2 branch enhances HttpClient in several
key areas and includes several notable features and improvements:
* 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. As of release 4.2 HttpClient will be using
pooling connection manager per default.
* 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.
Please note that new features included in this release are still considered experimental and
their API may change in the future ALPHA releases.
