Picture support has changed (but Subsurface ignores tags it doesn't
understand). So if you stored pictures with the development version, you
won't see them in 4.1 and after storing the file again with 4.1 they will
be lost.

In general I can only stress what Miika said - make backups BEFORE using
development versions and have a close eye on changes to the XML file. We
have been known to seriously break things and to lose information in dive
files. We obviously try no to, but it does happen.
