sounds great! I totally agree that PyMVPA deserves a good
version-number. It's too stable and feature for a 0.?-number, and also
a differentiation between 0.4 and 0.6 as mvpa and mvpa2 sounds nice to

> We believe that we have now settled on a plan to address everybody's needs
> as best as we can. The plan goes like this:
> 1. We won't break the API of the 'mvpa' python package. That package
>   will always provide the 0.4 series of PyMVPA and we'll maintain it for as
>   long as it is necessary/feasible. No new features will be added to it.
> 2. We will release the next major version of PyMVPA as an 'mvpa2'
>   package (i.e. API version 2). This will be what we have been
>   referring to as PyMVPA 0.6 so far. Following the principle of least
>   surprise we'll bump the version of this release to 2.0.0.
> What does it mean?
> The old and the new PyMVPA will be co-installable on any system
> without the need for any workaround or virtual environment. Your old
> scripts will continue to run, but at the same time you'll also be able
> to start using PyMVPA 2.0 for new projects.

> to
>  from mvpa2.suite import *
> but that's all there is to do.
> We are currently running the final test series to make sure the renaming did
> not have unexpected negative side-effects. Once this is done, you can expect
> PyMVPA 2.0 to appear for download on http://www.pymvpa.org.
> Thanks for your patience!
