spine-unity-4.2-2026-03-11.unitypackge errors

I'm running Unity 6000.3.7f1 on Windows and I'm getting the following obsolete/depreciated errors when I try to load the spine-unity-4.2-2026-03-11.unitypackge

Does anyone have any insight into resolving these?

That fixed it thanks!

@eblondin I've deleted Spinebots reply as it was outdated and no longer correct:
The spine-unity 4.2 unitypackage on the download page (and on github) is compatible with Unity 6000.3. We could not reproduce the issue you're getting (just tested with the latest version 6000.3.13f1), we just receive warnings warning CS0618: .. is obsolete instead of errors. Did you perhaps enable "Treat warnings as errors" in your project? In general these warnings should not cause any issues.

Anyway, if you have already upgraded to 4.3-beta, that's great if that's an option for you. You should then really stay with version 4.3 as it will be promoted to be the new stable release rather soon, providing you with bugfixes and ongoing support of new Unity versions in the future.
