We're in the begining of a GNUstep transition, which is unfortunately
blocked by serious issues on hppa.  As the release team is unlikely to
approve a new upstream release at this point, any eventual problems in
oolite must be addressed with an upload of the present version to
t-p-u.

So I suggest to upload this new release to experimental, not sid.
(But feel free to consult with -release (CCed)).
