Patch Changes

• 58bb052c #3670 Thanks @urugator! - fix #3669: SSR: useSyncExternalStore throws due to missing getServerSnapshot

• 473cb3f5 #3718 Thanks @mweststrate! - - Fixed observer in StrictMode #3671

  • [BREAKING CHANGE] Class component's props/state/context are no longer observable. Attempt to use these in any derivation other than component's render throws and error. For details see https://github.com/mobxjs/mobx/blob/main/packages/mobx-react/README.md#note-on-using-props-and-state-in-derivations
  • Extending or applying observer classes is now explicitly forbidden
