Changelog

v2.2.0 - 5 August, 2026.

Data Grid on TanStack Table v9:

• TanStack Table v9 is a foundational rewrite upstream: features are modular and tree-shakeable, state moves onto TanStack Store for fine-grained reactivity, and the core row model is reported around 79% faster with far lower memory use - Release notes.
• The Data Grid primitive now runs on TanStack Table v9. Tables are created with useTable({ features: dataGridFeatures }), so there is no more per-table getCoreRowModel / getSortedRowModel / getFilteredRowModel / getPaginationRowModel wiring - Docs.
• New public surface on the installed primitive: the ready-made dataGridFeatures bundle, plus the DataGridFeatures, DataGridTableInstance, DataGridColumnMeta and DataGridLayoutProps types - Docs.
• Installing the grid no longer widens TanStack's ColumnMeta for every other table in your app. The global module augmentation is gone, replaced by a DataGridColumnMeta interface wired through the bundle's columnMeta slot - Docs.
• The React Compiler opt-out is no longer the default. "use no memo" came out of 362 of 396 registry files; the primitive reads state through TanStack's Subscribe instead, and the Data Grid examples that still need it carry a comment saying why - Docs.
• All 30 Data Grid examples, the two Filters examples that drive a grid, and all 78 Pro blocks per base were regenerated on v9, in both the Base UI and Radix twins - Preview.

Breaking changes:

• Column pinning moved from left / right to start / end. That covers initialState.columnPinning, column.pin() and getIsPinned(), and the emitted data-pinned, data-last-col and data-outer-pinned-col attributes. CSS selecting [data-pinned="left"] needs updating to [data-pinned="start"] - Docs.
• DataGridProps takes a leading TFeatures generic, useDataGrid is generic, and the sub-component prop types are feature-parameterized. VisibilityState is now ColumnVisibilityState - Docs.
• The grid needs @tanstack/react-table v9 in your project. The docs ship a copy-paste migration prompt that walks a coding agent through the whole port - Docs.

Data Grid improvements:

• Row drag and drop holds the other rows still instead of sliding them apart, and marks the destination with an indicator bar. New dropIndicator prop, on by default - Preview.
• The row drag clone is portalled to the document body and measured to the row it was lifted from, so it stays under the pointer inside containers that create a fixed-position containing block, and no longer grows on dense or wrapping rows - Preview.
• Columns marked meta.autoSize stay resizable. A width you drag by hand is no longer overwritten by the next viewport measurement - Preview.
• Column resizing draws a full-height indicator at the pointer, exposed as data-slot="data-grid-table-resize-indicator" for styling - Preview.
• New docs throughout: a TanStack Table v9 setup section, a pinned-cell attribute reference, a row reordering contract, and a rewritten React Compiler section - Docs.

New Pro Blocks:

• New Files category under Solutions, opening with Drive Explorer: a full-height file manager with a folder tree rail, a folders band, and switchable list and grid views driven by one table instance, plus view settings, bulk selection actions, and separate empty states for an empty folder and a filtered miss - Preview.

New Ultimate Icons:

• 76 new icons added, 638 in total across 30 categories - Preview.

Fixes & Improvements:

• The Icon Tile primitive scales its corner radius with the tile instead of using one flat value, so the softer styles no longer render their xs and sm sizes as full circles - Preview.
• Four new twin-parity test suites lock the grid's selection, pinning, sorting, pagination, visibility, resizing and row reordering across both bases.
• The MCP search index picked up 10 registry items that shipped but were not discoverable through search - Docs.
• Docs pages now paint their article immediately and stream the Copy Page button and frontmatter badges in behind it - Docs.

v2.1.8 - 2 August, 2026.

Data Grid tree rows:

• Tree rows in the Data Grid primitive - recursive getSubRows at any depth, with the DataGridTableRowExpand toggle supplying per-level indentation - Preview.
• Tree rows work with every existing feature: sorting keeps subtrees attached to their parents, pinned and resizable columns keep the indent intact, and virtualization treats expanded children as ordinary rows - Docs.
• Cross-parent row drag and drop in tree grids, with drop indicators and depth guides through renderRowDecoration - Docs.

New Free Components:

• Tree rows example component - Preview.

New Pro Blocks:

• 4 grouped and tree Data Grid blocks, including a multi-level bill of materials with rolled-up cost and supply risk - Preview.
• New drag and drop Data Grid block - Preview.
• 3 new Event Calendar blocks - Preview.
• New Gantt block - Preview.

Fixes & Improvements:

• MCP OAuth refresh no longer invalidates a connection when a client re-presents the token it already rotated, so headless agents stay signed in - Docs.
• Connected apps on your account now show a disconnected connection instead of hiding it, with instructions to reconnect - Preview.
