+- fix [1535](https://github.com/gridstack/gridstack.js/issues/1535) use batchUpdate() around grid init to make sure gs-y attributes are respected.
 - fix [1545](https://github.com/gridstack/gridstack.js/issues/1545) `disableMove()` correctly prevents drag later (remove events and draggable attribute)
 - fix [1546](https://github.com/gridstack/gridstack.js/issues/1546) resize no longer delayed, which caused race conditions errors
 - fix [1001](https://github.com/gridstack/gridstack.js/issues/1001) resizing near bottom/top needs to auto-scroll/. thanks [@hbcarlos](https://github.com/hbcarlos)!
