Stefan suggested rightly to move this discussion to the mailing list. I also changed the language into english for that purpose.
Maurice' original questions were: (a) whether the new release would be algebra-only (short answer: hopefully). (b) whether our talk of a new release also refers to submodules, such as probxml and pftijah (short answer: yes) (c) whether all issues on the wiki, see: http://www.pathfinder-xquery.org/wiki/index.php/Jupiter:_The_Algebra_Release needed for this action, have already been resolved (short answer: no) On Tue, Oct 16, 2007 at 05:23:43PM +0200, Peter Boncz wrote: > Hi Maurice, et al, > > The release of (hopefully) this week will still be mps based.
