- default configuration now centralized in DHParser/configuration.py
- dropped python 3.4 support
- infinite loops in ZeroOrMore, OneOrMore and the like will now simply
be broken rather than reported as an error
- better parser-optimization, i.e. flattening and dropping of irrelevant
nodes while parsing already.
- no caching of node.content anymore, because this was conceptually
unsound. Trees are refactored and nodes dropped all the time which
would require invalidating the cache, which would be hard to implement.
- mini-framework for static grammar analysis added (see parse.Grammar).
As of now: no use case
