wangzi This warning is displayed because changing the version of the editor you are using will make some of the hotkeys available in the new version unavailable. You can ignore it and continue working, but if you find it annoying to see the warning every time, you can stop it from appearing by deleting the hotkeys.txt file in your user folder. If you haven't changed the hotkeys settings from the default settings, then simply deleting it is fine, but if you have changed the settings, you may want to copy it as a backup, delete it, then start the Spine editor and restore the changed settings after the hotkeys.txt file has been regenerated.
The path to the user folder differs depending on the OS, so please refer to the following troubleshooting page:
