Hi all, we made an attempt to support saving session files for previous versions of PyMOL. The latest changes in the SVN repository introduce the "pse_export_version" setting. So if you want to send someone a session file that can be opened with PyMOL 1.7.4, you can do:
set pse_export_version, 1.74 save session.pse There are limitations. For details, see: http://pymolwiki.org/index.php/pse_export_version Cheers, Thomas On 08 Apr 2015, at 15:12, Thomas Holder <thomas.hol...@schrodinger.com> wrote: > Hi Matt, > > there might be room for improvement regarding our versioning scheme. > Nevertheless, in the last year, a "point update" with no changes in the > session file format would be an increment in the 4th position (x.x.x.y). > > Also, 1.7.5 code so far only lives in the SVN repo, there is no 1.7.5 release > (the next release will be 1.7.6 or 1.8.0).
