The PyAMF team is proud to announce a new release of PyAMF, a
lightweight library that allows Flash and Python applications to
communicate via Adobe’s ActionScript Message Format.
Lots of changes for this one, a brief overview:
• A new C extension to pyamf.util and pyamf.amf3. This is a work in
progress and using Cython  more sections of the library will be
moved to C as they are identified. Thanks to Gerard Escalante.
• An adapter for SQLAlchemy  is available, allowing object graphs
to be easily encoded. See the wiki  for more information. Thanks to
Dave Thompson and Michael Van Tellingen.
• Improvements to the Google App Engine adapter  to allow
datastore objects to be easily encoded/decoded.
For a detailed list of changes, see the change log .
To download this release either grab a compressed file , use
‘easy_install -U pyamf’ or grab the Subversion tag .
This is a release candidate so depending on feedback, 0.4 final 
will be available in a few days.
