Relevant changes:
* quoted data urls which are not base64 encoded keep their spaces now
* accept bytes and text as input. All other types now raise a TypeError
* update python & gcc support
* python version will only accept the C implementation if the versions
match exactly. This should prevent using older installed C versions.
Along with the version bump:
- update maintainer email address
- use $(AUTORELEASE)
