There’s no rule. Unless there is a particular fix or new/improved functionality you’re looking for, you generally don’t need to be in any rush to update. The only recent exceptions I can think of is when there have been significant security changes – it’s worth getting those. [You already have the most recent ones I’m thinking of.] Of course. Your version has the new launcher, so you can select Upgrade/Downgrade from the menu, and roll back to an earlier version.
