Is it safe to use latest beta, considering recent changes..?

I know it's a nearly dumb question.
But it makes sense if you consider

v9.30.0012 - 2010-07-24 17:03
~~~ Tabs: Heavy rewriting of the code base became necessary to make
portable tabs really shine. You should note nothing of it if all
worked out.
Whatever, it's a good day to make a backup of your app data!!!

and

v9.30.0016 - 2010-07-26 19:52
! Tree: Improved the automatic refresh of the Tree pane for non-
current folders. Now all nodes (incl. special paths) should be
updated correctly, directly and smoothly, including all folder
related data like highlights, tags, favorites, thumbnail caches
etc. -- even if those nodes are not shown currently in the tree!
As long as XY is running then every change to the file system by
any other app should be auto-adjusted to in XYplorer's various
path related data. That's the goal and we are quite near.

along with

v9.30.0019 - 2010-07-27 10:52
+ Moving or renaming items with XYplorer did not notify the shell
about it, so other apps could not auto-update their display
accordingly. Now the notification is done.

These are really important changes and I'm a bit anxious to actually WORK with them expecting no significant flaws.

All seems fine so far.

Also on my side... At least with the trial runs... Time to upgrade, then... (gulp!)
Thank you, Don! Excellent work!
