0.4.0 Bytestring instead of Bytestring.Char8

0.3.0 State Linkage Exception in license

0.2.0 The mime package (Codec.MIME) switched from String to Text in 0.4. We follow. Thanks, Dave!

0.1.1 Dependency for bytestring set to 0.10

0.1.0 Major changes:

      - Compliance with Stomp 1.2:

      - header keys and values are now escaped;
        this, in fact, was missing for Stomp 1.1.

      - header keys and values are not trimmed or padded;
        this, as well, should have been done for Stomp 1.1 already.
        Be aware that Stomp 1.0-like message headers
        may fail now, *e.g.*:
        *message : hello world*
        is not the same anymore as
        *message:hello world*

      - carriage return (ascii 13) plus line feed (ascii 10) 
        is now accepted as end-of-line;
        note that stompl never generates carriage return as end-of-line,
        the standard end-of-line remains line feed.

      - the Message frame may have an *ack* header 
        and should have when a message is sent 
        through a queue that requires explicit ack.

      - the mandatory header in the Ack frame is now *id*
        instead of *message-id*. It should correspond to *ack*
        in the message that is ack'd.
        Note that, to ease backward compatibility,
        Ack frames are generated with both: 
        an *id* and a *message-id* header.

      - a Stomp frame was added.
        The Stomp frame has exactly the same format
        as the Connect frame, but it is handled differently
        with respect to escaping: Connect header keys and values 
        are not escaped, Stomp header keys and values, however, are.

0.0.3 Major changes:

      - new attribute "ClientId" in Connect frame 
        for compatibility with ActiveMQ; 

      - all commands accept additional headers
        to ease adaptations to broker-specific features. 

0.0.2 Minor corrections and documentation
