Hi All,
I'm very happy to announce the first TestFixtures release built after a
continuous integration testing process.
The main benefit of this is that TestFixtures now works with Python 2.5
and Python 2.7. I thought they did before, but there were some annoying
niggles.

Does Python 2.7's zipfile module use its own algorithm or does it
leverage the zip/unzip libraries that exist on the host? I ask
because my host's native unzip program cannot handle files that, when
unzipped, are larger than 2GB. Will using Python 2.7 get around this
limitation?

Agreed that it's a bit surprising. It's a consequence of NumPy's
