Breaking change (React, Angular, Vue 2, Vue 3): Changed Handsontable's policy toward older versions of supported frameworks. From now on, Handsontable supports only those versions of any supported frameworks that are officially supported by their respective teams. Dropping Handsontable's support for any older framework versions won't be treated as a breaking change. #10396
Breaking change: Changed the order in which three hooks are executed: now, the beforeChange hook is fired before the afterSetDataAtCell and afterSetDataAtRowProp hooks. #10231
Changed the margins of the context menu in the RTL layout direction. #10375

Breaking change (Angular): Dropped support for Angular 13 and lower. From now on, Handsontable supports only those versions of Angular that are officially supported by the Angular team: currently, it's 14-16. However, Handsontable 13.0.0 was thoroughly tested and, to the best of our knowledge, works correctly with versions down to Angular 12. #10396
Breaking change: Removed the deprecated beforeAutofillInsidePopulate hook. #10407
Breaking change: Removed the deprecated getFirstNotHiddenIndex method. Instead, use the getNearestNotHiddenIndex() method. #10407

Breaking change: Removed the deprecated parameters of the populateFromArray() method: direction and deltas. #10407
