Is there any approved way to downgrade to the last stable release?

What was the last stable release? I have 5.10 and I think it is OK, but I am only using it as a backup (to an LX9000) so I am not certain.

This saga certainly encourages you not to be in a hurry to update! And also to keep copies of each version you install on your PC (don't know how that works if you use the updater). Incidentally, I have not yet updated my LX9000 to v 4, which is currently on 4.04!
