 * The findings are clear: the admin script `admin.min.js` triggers a `beforeunload`
   warning on `post.php`. Whenever I exit the WP Editor, I always get a warning 
   that something hasn’t been saved. My version: 3.9.88

 * Hi [@pecco01](https://wordpress.org/support/users/pecco01/) ,
   Thanks for reporting
   this. The unsaved changes warning on the post editor was caused by `admin.min.
   js` in version 3.9.88, and it’s now fixed in **version 3.9.89**.Please update
   the plugin and clear your cache. The warning should now appear only when there
   are actual unsaved changes.Let us know if you need any further help.Best regards
