## 2.0.0dev4, 2012-01-23

This is to become v2 of the known pecl_http extension.

List of changes (TBD):
* Everything lives below the http namespace
* The message body is implemented as a temp stream instead of a chunk of memory
* The utterly misunderstood HttpResponse class has been reimplemented in the http\env namespace
* There's only http\Exception
* Every instance follows http\Object::$defaultErrorHandling or inherited http\Object->errorHandling, but only for errors generated by the extension itself
* You have to use the http\Request\Factory to create your requests/pools/datashares
