Since mortal users like me are not allowed to post to geda devel, I'll throw in my 2 eurocent here in geda.user: Please try to make format bumps so, that it is still possible to share geda/pcb documents in a heterogeneous environment. That is, in an environment where some of the users go with bleeding edge versions from git, while others go with the package their distro provides. This may be achieved with an option to save in old format. Or there may be an external conversion script to turn the new file format into the old format. If this means that some features of the new PCB version won't survive the conversion, then issue a warning and convert anyway. The user of bleeding edge PCB may avoid these features if compatibility with older versions is needed. An example for such a feature is the holes in polygons recently added to PCB format. Backward incompatibility hit me unsuspecting a few months ago, when I tested the improved grid patch. A quick test with a dummy project looked promising. So I started using it for real world projects. It was a royal pain to get the modified layouts back into old style format. If the bleeding edge version of PCB produces files my colleagues can't open, then I can't use it for day to day work. My testing will be casual at best. ---<)kaimartin(>--- -- Kai-Martin Knaak Email: k...@familieknaak.de Öffentlicher PGP-Schlüssel: http://pool.sks-keyservers.net:11371/pks/lookup?search=0x6C0B9F53 _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
