Hi all,
This is a heads up that the numpy version string for development versions is changing from x.y.z.dev-githash to x.y.z.dev+githash (note the +). This is due to PEP 440 [1], which specifies local (i.e. non-released) versions have to use a "+". Pip 6.0, released a few days ago, enforces this so we noticed immediately that without this version string change pip sorted the latest dev wheel build from master below any released version.
Change in numpy at [2]; identical change in scipy at [3]. Note that this is unlikely but not impossible to break custom version string parsers (like [4]).
