Yes, this is a question that some of us have. Not just with new Bubble versions, but with new plugin versions. Especially some who release new versions every single day “just to update marketing stuff,” but I’ve encountered bugs and other issues. And some mass plugin creators who fail to provide the proper support they should, so when they try to fix one bug, they create two more — sometimes those silent bugs that are the worst.
One of my active apps is on an old version, and I’m a little wary of updating directly to the latest version, especially because since I remember, you can only revert to a version prior to the current one, but maybe this has changed.
So I think the ideal would be to go slowly and test each new update until you reach the most recent one. You can check what each new update promises to change in the changelog and then focus on verifying those things.
