I was supriced that the following code returns True. parse_version("0.1dev") > parse_version("0.1rc") A rc release should in my mind be newer then a dev version. Turbogears has a problem with this regarding SQLObject. TG requires SQLObject 0.7.1dev-r1860 but can't use SQLObject 0.7.1rc1 which is a newer release. -- cheers elvelind grandin
