 ## 9.5.0 (2023-10-26)
 * feat [#1275](https://github.com/gridstack/gridstack.js/issues/1275) div scale support - Thank you [elmehdiamlou](https://github.com/elmehdiamlou) for implementing this teh right way (add scale to current code)
 * fix [#2489](https://github.com/gridstack/gridstack.js/commit/2489) moved the dropped event handler to after doing everything (no more setTimeout) - Thanks [arnoudb](https://github.com/arnoudb) for suggesting a fix.
