0.2.x

The 0.2.x series is a major revision, not backward compatible with 0.1.x.

0.2.0

Removed Request::current, because it won’t work well with single-threaded concurrency models (fibers, eventmachine and the like) and it’s not essential.
Rackful::Server#call was made reentrant. This is necessary for response code 100 Continue.

The 0.1.x series is a major revision, not backward compatible with 0.0.x.

Fixed the gemspec file. Not everything new was properly included (including this changelog!).

Complete revision of the Rackful::HTTPStatus exception class. From now on, there’s a separate class for each HTTP status code, e.g. Rackful::HTTP404NotFound.
Rackful::Path, a subclass of String, is used for HTTP paths. This allows serializers, especially for hypermedia, to distinguish paths from “ordinary” strings, and render them accordingly.
The concept of Rackful::Serializer Serializers was introduced. A serializer is an object that knows how to serialize an object to a certain media type.
The mechanism for content negotiation has changed completely. See Rackful::Resource#serializer and Rackful::Resource::ClassMethods#best_content_type.
The mechanism for implementing HTTP method handlers has changed. See Rackful::Resource#do_METHOD and Rackful::Resource::ClassMethods#add_parser.
