+#### Fixed
+- Fixed copying, cutting, and pasting doing nothing in a grid embedded in a Salesforce Lightning Web Component. [#13388](https://github.com/handsontable/handsontable/issues/13388)
+- Fixed a `filters` plugin crash thrown when a cell in a filtered column was edited, or the data was replaced with a filter active, after `updateSettings()` was called with the `filters` option (as the React and Angular wrappers do on every update).
