Fixed

• Fixed an issue where the Nested Rows plugin was disabled after calling updateSettings with an empty data array. #10556
• Fixed setSourceDataAtCell() updating parent rows instead of nested child rows when nestedRows is enabled. #10657
• Fixed an issue where the stretchH: 'last' option would ignore the defined column width when the viewport was too narrow, causing the last column to shrink to 0px. #11761
• Fixed a stack overflow error when pasting large datasets (50,000+ rows) by optimizing array operations in the HTML table parser. #11784
• Fixed incorrect JSDoc type annotations for the modifyAutofillRange hook parameters. The parameters entireArea and startArea are now correctly documented as number[] (a flat 4-element array) instead of the generic Array type, and the @returns type annotation has been added. #11862
• Fixed filter by value input performance degradation when searchMode: apply option is enabled. #12104
• Fixed getCellMetaAtRow() to always return cell metadata in physical column order. #12109
• Fixed the modifyAutofillRange hook type signature to match runtime tuple arguments and return value #12113
• Fixed incorrect parsing of comma-grouped values in numeric cells #12114
• Fixed comment editor positioning for merged cells #12115
• Fixed the Filters plugin incorrectly applying filter conditions after columns were moved with the ManualColumnMove plugin. #11832
• Fixed column resizing being misaligned and calculating incorrect widths when the grid container has a CSS transform: scale() applied. #11838
• Fixed the stretchH: 'last' option ignoring the defined column width and shrinking the last column to 0px when the viewport was too narrow. #11761
• Fixed HyperFormula errors when MultiSelect cells store array values. #12135
• Fixed setSourceDataAtCell() updating a parent row instead of the intended nested child row when the nestedRows option was enabled. #10657
• Fixed setDataAtRowProp() incorrectly canceling an active editor session when the programmatic update targeted a different cell in the same row. #4305
• Fix ThemeBuilder false unknown token warning on initialization #12146
• Prevent after scroll hooks from firing when axis position is unchanged #12151
• Fixed six regressions related to rowspans in nested column headers. #12152
• Fixed undo restore for mixed checkbox multi-selection delete. #12153
• Fixed Ctrl+A selecting the entire grid instead of the comment text when the comment textarea was focused. #12193
• Fixed columnHeaderHeight overriding the actual content height, causing overlay THEAD misalignment when header text wraps. #12198
• Fixed selected fixed-column header alignment with data cells for fixedColumnsStart #12202
• Fixed autofill over hidden columns when Formulas is enabled and hiddenColumns.copyPasteEnabled is false #12203
• Fixed a one-pixel horizontal misalignment of the left pagination caret in the Pagination plugin. #2791
• Fixed nested headers crash when sorting with disabled current highlight. #12211
• Improved server-side data documentation structure and fixed disjunctionWithExtraCondition guard fallback in server filter utility examples. #12241
• Fixed framework wrappers crashing when init-only settings (renderAllRows, renderAllColumns, layoutDirection, ariaTags) changed after initialization. #12242
• Fixed an issue where currentRowClassName and currentColClassName could not be changed dynamically using updateSettings. #12247
• Fixed column menu dropdown button styling when a filtered column header is also active #12253
• Fixed an issue where rows with dataSchema default values (e.g., false for checkbox columns) were not recognized as empty by isEmptyRow and isEmptyCol, causing minSpareRows and minSpareCols to add infinite rows. #12254
• Fixed autocomplete editor with strict mode and allowInvalid discarding typed value on click-away instead of saving it. #12285
• Fixed incorrect JSDoc type annotations for the modifyAutofillRange hook's entireArea and startArea parameters, and added the missing @returns annotation. #11862
• Fixed filter-by-value search by trimming leading and trailing spaces and treating whitespace-only input as an empty query. #12290
• Fixed portal-based popups (e.g., date picker) closing immediately on touch devices (Android) due to outside-click detection not accounting for rootPortalElement. #12298
• Fixed setDataAtRowProp ignoring the source parameter in array-form calls, causing beforeChange and afterChange hooks to always receive 'edit' instead of the provided source string. #12300
• Fixed multiple Handsontable tables with shared HyperFormula engine and auto-sizing becoming unresponsive due to cross-table formula update interference. #12305
• Fixed disableVisualSelection treating undefined as true instead of falling back to the default (false). #12307
• Fixed incorrect return types for in some hooks #12309
• Fixed multiselect overflow indicator not responding to chip padding token changes #12316
• Fixed the headerRowBackgroundColor theme token having no visual effect on row headers. The rowHeaderOddBackgroundColor and rowHeaderEvenBackgroundColor tokens now derive from headerRowBackgroundColor by default, so customizing it properly cascades to all row headers. #12322
• Fixed an exception when showing the loading indicator from the afterChange hook during editor close. #12348
• Fixed TypeScript type for the dateFormat option to accept Intl.DateTimeFormatOptions objects required by the intl-date cell type. #12395

• Fixed one-pixel horizontal alignment for the left pagination caret #2791
• Fixed setDataAtRowProp interrupting edits in progress #4305
• React: Fixed the React wrapper skipping settings updates when dataSchema or columns contains non-plain objects such as Date, Set, or Map. #12207

• Patched critical and high dependency vulnerabilities across the monorepo and aligned Angular wrapper tooling for compatibility. #12237
