Spine version compatibility

hey
We have been developing a game using Spine for the past five years, but there was a one-year break in development. Our project was created with Spine version 3.8.99, and the Unity runtime scripts were matched to that version.

Now that we’ve resumed development, I can no longer find the old Spine version.

If we switch to the latest Spine version, will it work with our existing Unity runtime, or will we need to update the runtime and re-export all our previous animations? Can the current Spine Unity runtime still support exports created in 3.8.99?

To ensure compatibility, the version of the Spine editor you use to export your animations must match the version of the Spine-Unity runtime you are using. If you switch to the latest Spine version, you will need to update your Unity runtime to match this new version and re-export all your animations from the new Spine editor. The current Spine-Unity runtime will not support exports created in 3.8.99 without updating the runtime to match the new Spine editor version.

Is there a way for me to use version 3.8.99 to finish the project?

You can and should use Spine Editor 3.8.99 if you target 3.8 runtimes.
You just have to select it from the launcher or choose the version within the editor from the settings. In the latter case, you need to restart Spine.

Using higher editor versions to export lower asset versions should be done only in exceptional cases, as it might lead to incompatibility.
