From the CHANGELOG:
0.8
More fixes for the App Engine support.
Added a new feature that allows you to supply your own provider for the
CA_CERTS file. Just create a module named ca_certs_locater that has a method
get() that returns the file location of the CA_CERTS file.
Lots of clean up of the code formatting to make it more consistent.
