You can of course, but it is "beta" level which means not all of the runtimes will be update to date, things are subject to change, and there may be bugs. We also can't say when the beta will be finished, though we're considering wrapping up 4.1 with a lot fewer of the features than we have planned, just to get it a non-beta version into people's hands sooner.

In practice we update spine-unity very quickly once new features are ready (it's currently up to date with 4.1-beta). We try very hard not to make breaking changes even in beta, though we do reserve the right to do so, worst case. There are often bugs as new features often means we rewrite large portions of the app, breaking things apart and reassembling them in a better way. We do try to fix them rapidly.

Going back a version isn't great and risks data loss that may require manual fix up. 4.0 -> 4.1 adds sequences and some other things. Going back shouldn't be too hard, though it's still quite risky. If you use sequences obviously they can't work in 4.0, which lacks that feature.

I feel that the 4.1 beta is far less bug than the 4.0 Beta

Hi guys,

I am working on a project that is planned to be released by the end of this year.

We use Unity, and Spine 4.0 version at the moment

Can we move to 4.1? is it ready at least for early prototyping.

And would it be easy to downgrade projects to 4.0 that are animated with 4.1 if anything happens?

I agree, at least so far (4.1.18-beta) the 4.1 beta is pretty stable. Due to that we'll likely do a few more quality of life improvements, then release it as non-beta. That means we'll push physics to 4.2 which is a little sad, but it's better to get what we have so far for 4.1 into your hands sooner.

Can this function be added in 4.2?

Cool Spine Functions!
