Joining in to say that this change has also made serious impacts on how I've been using - the same way I've been using it for years.
Sure, having a version happen each time you save might not work with industrial version control, but for single seat, non-collaborating users, it's just fine, and has been just fine.
Fun fact, folks -- the versions are still there. Install the Parametric Text plugin, create a sketch, and enter a text of "v". Open Parametric text (Modify, Change Text Parameters) and click on the "v" text in the sketch you just created, and it'll select in the window. Add "{_.version}" to the "v" in your text, and click OK, and you will see the text changes to something like "v4". Save the design (without being able to say why you're saving the design, another dumb change) and you'll see that version number increments.
So they haven't completely removed the old versioning, they just hid it from you. Does that make it better or not? 😆 Creating a new version (the new way, which was noticably slow) doesn't even touch the internal version number.
I've got to say, first the non-optional, unwanted "What do you want to do?" pop-up, then screwing around with this Part/Hybrid/Assembly, now nuking the versioning so many of us rely on... it's actually had me seriously thinking about looking at other solutions. The migration would be a nightmare, I've got years of designs that would have to be moved, but man, it sure seems like the Fusion team is trying to push me that way.
