notebook worksheet revisions

13 ●3

On sagenb.com in any worksheet there is the button "revisions". How do I launch or setup my notebook so I too can have it? It is very useful!

version() on my server and sagenb.com returns the same: 'Sage Version 4.7.2, Release Date: 2011-10-29'

This is the "Undo" button on previous versions of Sage (sagenb.org uses the "flask" notebook and has a number of other changes/optimizations).

Warning: currently these revisions don't seem to do anything. In fact, haven't for quite some time - or are you finding that the revision are useful?

I hadn't tested this when I was writing the question =) Too bad it doesn't work! It would be very handy in my study =( Thank you for your answer

Yes, it is unfortunate. Hopefully it will be fixed soon - it *used* to work but now doesn't, sort of as a "feature".
