I grabbed a version of the trunk on May 3rd which I have used quite
successfully for several deployed projects along with Django 1.2.1 and
Python 2.6.5. At the time it was marked in setup.py as version
"0.2.3rc1". I currently consider every version of piston other than
that particular drop to be either inferior or suspect. Sadly I don't
know enough about the inner workings of mercurial to give you any more
guidance than that. (If someone knows of a way I can peruse the .hg
area to get info that would enable others to pull the same bits from
bitbucket that I did, then please let me know.)
I have been hoping for a new official release of piston for months,
but sadly that appears to be getting farther away rather than closer
as far as I can tell. This means that I have had to remove piston from
one system in order to simplify the deployment process for our
customer. This means that one of the largest and most respected hi-
tech companies in the world will not be deploying a piston-based app
after all. (Actually in this case piston was probably overkill for
their needs anyway.)
