getDynamicChild still works in 0.3 but you get a deprecation warning
when it exists. It will stop working in 0.4. The replacement is named
childFactory and the only difference is the order of the arguments,
which was changed to be consistent with the rest of nevow:
def getDynamicChild(self, name, ctx):
def childFactory(self, ctx, name):

locateChild is the only traversal API required by IResource. It is
called directly by the object publisher (NevowSite).
The default locateChild implementation on nevow.rend.Page looks in two
childFactory (replaces getDynamicChild)

The changes will start to slow down now. Most of the major refactorings
which I wanted to take place have happened, so it should mostly be
minor bugfixes and new feature additions going forward.
