Changelog

v2.6.2 - 24 September, 2026.

10 new App Shell blocks lead this release, with 3 new Pro block categories for marketing pages (Compare, How It Works and Pricing) and 11 CTA blocks. Shipped features land on the roadmap.

New Pro Blocks:

• 10 new App Shell blocks, from a sidebar-free top nav and a folder-tab workspace to security consoles with a drag-to-reorder scope tree - Preview.
• New Compare category with 3 versus sections: a 3-column feature matrix, an emerald capability card beside a prompt-only list, and 2 step tracks across a VS rail - Preview.
• New How It Works category with 5 blocks: 3, 4 and 5 step card grids, plus 2 tabbed walkthroughs that swap a product console per step and advance on their own - Preview.
• New Pricing category with a 4-tier pricing table: a monthly or yearly toggle with a Save 20% badge, and a seat stepper that reprices the Team plan - Preview.
• 11 new CTA blocks: WebGL Earth and Mars banners, a newsletter signup, logo marquees, an MCP integrations grid, an outcome checklist and a review rating pill - Preview.
• New Data Grid rate card block: a cloud SKU price book with stacked discounts, commit usage bars, a list-to-net price breakdown dialog, Filters, and add, edit and delete - Preview.
• App Shell is now 31 blocks and CTA 17, taking the Pro catalog from 544 to 575 - Preview.

v2.6.1 - 22 September, 2026.

New: Deal Pipeline Workspace.

• New CRM 7 Pro block: 48 deals across 12 accounts in 4 linked views, built on the Data Grid, Kanban, Event Calendar, Gantt and Filters primitives - Preview.
• Table view groups deals by account and carries open and weighted totals on every band and in the footer, with inline cell edit - Preview.
• Board view lanes by stage, and a drop settles the deal's probability and close date - Preview.
• Closed Won and Closed Lost are droppable rails on the board, and locked or already-closed cards are disabled items rather than a drop the board refuses - Preview.
• Calendar view draws the next activity and the close date as 2 switchable layers, so an overdue step reads against the month it belongs to - Preview.
• Timeline view expands an account to its deals and rolls weighted pipeline up to the account row, where a bar covers the deal's open-to-close window and only its close end moves - Preview.
• Search, filters and color are shared by all 4 views, while the Table and Board each keep their own grouping and the Display popover holds per-view layout - Preview.
• Create, inline edit, drag, bulk restage, reassign and delete run from every surface through one write path, 20 steps of undo deep, with Undo on the toast - Preview.
• The record sheet marks a deal won or lost, logs an activity and schedules the next one, clearing the next step when a stage closes the deal - Preview.
• An account is a grouping row rather than a record, so a filter that empties a view says so instead of rendering a blank grid - Preview.
• Solutions CRM is now 7 blocks, taking the Pro catalog to 544 - Preview.

v2.6.0 - 17 September, 2026.

New Free Components:

• New Sidebar category: 5 app shell examples covering a collapsing icon rail, a floating off-canvas inspector, docs navigation with sub-menus, menu badges with row actions, and skeleton loading - Preview.
• New Message category: 7 chat transcript examples covering avatars, sender and delivery metadata, reply actions, shared files, grouped turns and a streaming reply - Preview.
• New Message Scroller category: 6 anchored transcript examples covering opening position, a reply that streams at the live edge, turn anchoring, a restored thread, loading earlier messages, and a thread navigator - Preview.
• New Bubble category: 7 chat bubble examples covering variants, sender alignment, grouped turns, reactions, a long reply that expands, quick replies and formatted assistant output - Preview.
• New Attachment category: 6 file chip examples covering a composer tray, an image strip, 3 sizes, every upload state and a file picker - Preview.
• New Marker category: 6 agent run log examples covering the 3 variants, tool call logs, run status, phase separators and linked rows - Preview.
• New Questionnaire category: 7 guided survey examples covering multiple choice, written answers, progress, skip, validation and conditional branching - Preview.
• Sidebar and Message Scroller examples render in their own preview frame, so each one sizes itself against its card instead of against the page - Preview.
• Every one of the 7 new pages links the Pro blocks built on the same primitive, and the App Shell, AI Chat, Agent Activity and Onboarding blocks link back - Preview.

Fixes & Improvements:

• The Data Grid and Alert Dialog pages pointed at /components/toast, which is not a page; both now link Sonner - Preview.

v2.5.5 - 16 September, 2026.

Breaking changes:

• ReUI items that merge classes now import cn from the cn package instead of your @/lib/utils, following shadcn upstream - Changelog.
• Any item that imports it lists cn in its dependencies, so shadcn add installs the package on the first such install - Docs.
• Items already installed keep working and your @/lib/utils is untouched - Docs.
• To drop clsx and tailwind-merge from your own project, run pnpm dlx shadcn@latest migrate cn - Changelog.
• If you had customized cn in @/lib/utils, rebuild it with createCn from cn/config; newly installed items no longer route through that file - Docs.

MCP server and Agent Skills:

• Every block and c-* example an MCP tool returns now carries a thumbnail image, so your agent can show you the item before installing it - Docs.
• New get_thumbnail tool returns the preview image itself for up to 4 items in one call, so an agent picks by looking instead of by score - Docs.
• get_component returns only the API sections you name, and trims a very large API on heading boundaries, listing what it dropped - Docs.
• compose_page labels every section by how well its block fits the intent, across 26 page types - Docs.
• search flags a weak match and names the query terms no item mentions, instead of ranking a near miss first - Docs.
• A free plan now sees a premium block that fits better than the free answer, as a preview with no install command - Docs.
• 4 Agent Skills slash commands - build, add, fix and improve - run the ReUI workflow from your agent's command surface - Docs.

Fixes & Improvements:

• Event Calendar timed views reserve a clickable strip at the end of each day column, so a press beside a full-width block creates a new event instead of doing nothing - Docs.
• The strip's width is --ec-event-gutter, and 0px restores edge-to-edge blocks - Docs.
• Data Grid pagination moved to an adaptive window carrying the first and last page, so page 40 of 40 is one click away rather than several ellipsis steps - Docs.
• Data Grid moreLimit sets how many page buttons that window shows, and the row holds a steady width as you page - Docs.
• Cascader virtual rows froze at their first window in apps built with React Compiler, which cached the row list against a virtualizer identity that never changes - Preview.
• Filters defaultOperator now documents what it does: the operator a rule falls back to when its field changes, not a preselection on create - Docs.
• MCP block and example results link each item's own docs page instead of its category page - Docs.
• Icon items declared no npm dependencies at all, so shadcn add installed 54 animated icons across 4 styles without the motion package they import - Preview.

v2.5.3 - 15 September, 2026.

New Pro Blocks:

• New Flow category with 4 node canvas blocks on React Flow: an automation workflow carrying per-step owner and last run status, an auto-laid-out agent branch tree, a dependency-ordered pipeline replay with a human approval gate, and a growth impact map whose metric links carry a correlation coefficient - Preview.
• New Agent Activity category with 5 agent run blocks: an approval-gated run console, a live feed with Summary, Detailed and Raw log views, a cited research timeline, an MCP call table carrying each server's refused scope, and an outcome report with a scoped retry - Preview.
• New Profile 10 block: a developer API keys page with masked tokens, roll and revoke, and SDK samples across 3 tasks and 5 languages - Preview.

Fixes & Improvements:

• 10 blocks declared fewer registry dependencies than they import, so shadcn add could leave a Popover, Hover Card or Toggle Group uninstalled - Preview.

v2.5.2 - 1 September, 2026.

New: Data Grid Editing API and Localization.

• DataGridCellSelection gains apiRef with focusCell(rowId, columnId, { edit }), landing cell focus, DOM focus and aria-activedescendant together on rows still mounting - Docs.
• Fill handle looks via tableLayout.cellFillHandleVariant: the default solid dot, an Excel-style square, or a Sheets-style hollow ring on the selection corner - Docs.
• tableClassNames.rowPinned, rowCreate and cellFillHandle override the pinned-row chrome, the add-row affordance and the fill handle - Docs.
• New getDataGridVisibleSelectedCellCount helper keeps a selection count consistent with the painted range - Docs.
• The virtual layout renders onRowCreate and appendRow, matching the standard body - Docs.
• onCellSelectionChange delivers a resolved selection snapshot: the focused cell, every bound, the active bound and the visible cell count - Docs.
• Per-row editability: cellEdit.editable accepts a function of the row, locking rows across paste, fill, clear and the editors - Docs.
• New invertDataGridCellsChange helper derives the undo batch from any onCellsChange payload - Docs.
• The imperative api gains clearSelection and scrollToCell, and the add-row label is localizable via rowCreateLabel - Docs.
• Copy and cut now work from the keyboard on every platform: Cmd/Ctrl+C and X write through the async clipboard API, since browsers never fire a native copy for a focused grid - Docs.
• Opt-in single-click editing via tableLayout.cellEditMode: "click"; double-click stays the default - Docs.
• The selection edge beside a pinned column is painted once, inside the cell, so browser zoom and fractional widths can no longer double it into a 2px blur - Preview.
• In-cell controls follow the two-step gesture: the first click on an unfocused cell only focuses it, the second activates the select, date or combobox, matching editor cells - Docs.
• Pinned columns now show the row hover and selected tints, premixed over their opaque background - Preview.
• Selected rows no longer draw the 2px start bar; the checkbox and row tint carry the state - Preview.
• i18n on DataGrid replaces every built-in string in one place, menu items and aria labels included, with function labels for interpolated copy - Docs.
• Opt-in column virtualization for DataGridTableVirtual: only the horizontal window of center columns renders, pinned columns stay mounted, with controlled scrollToColumnIndex - Docs.
• onCellsCopy reports every clipboard write with the copied grid and a cut flag, for toast confirmations - Docs.
• tableLayout.cellEditEnterAdvance restores the Sheets move-down; an Enter commit now keeps focus on the edited cell by default - Docs.
• data-cell-control marks a custom widget whose active surface is wider than its buttons, so a press anywhere on it follows the two-step gesture - Docs.
• 3 new examples: a localized grid with an EN / DE / JA switch, a 36-column virtualized matrix, and a server side paginated grid with a debounced search and a status filter, taking the Data Grid to 34 examples per base - Preview.
• Server side pagination is documented end to end: pass the server total twice, as rowCount on useTable for the page buttons and as recordCount on DataGrid for the info text - Docs.

New Pro Blocks:

• New AI Agents group with 12 AI Chat blocks: copilot shells, docked and floating assistant panels, welcome screens with prompt starters, side by side model comparison, voice turns, branching threads and grounded docs support - Preview.
• New Data Grid Editing 5 block: a virtualized spreadsheet task grid with cell ranges, clipboard, drag-to-fill, built-in and in-cell editors, a rule-based filter builder, and an undo stack instead of a save bar - Preview.

Fixes & Improvements:

• DataGridCellSelection: Sheets-style chrome, with a lighter tint, a solid perimeter that tracks the drag, an unfilled anchor cell and a dashed fill marquee - Preview.
• DataGridCellSelection: the perimeter's top line is clamped inside the first row, so a sticky header cannot paint over it - Preview.
• DataGridCellSelection: the perimeter survives the first and last column and the last row, and the fill handle stays inside the grid - Preview.
• DataGridCellSelection: the built-in editor sits exactly on the cell, so opening it no longer grows the row by 2px, and it is named after its column - Preview.
• DataGridCellSelection: copy, cut, clear, paste and fill act only on visible rows, so a page-boundary range cannot write hidden ones - Docs.
• DataGridCellSelection: a fill across columns runs the target's parse and reports rejections, like a paste - Docs.
• DataGridCellSelection: Shift and arrows still extend a range after a modifier click on a control cell - Docs.
• DataGridCellSelection: Escape on an in-cell control returns focus to the grid, and AltGr chords type instead of selecting all - Docs.
• DataGridTable: columnsResizeMode: "onChange" writes widths to the table element, so a drag costs no React render per move - Docs.
• DataGridTable: pinned header cells stay put under a sticky header, so the corner no longer scrolls away - Preview.
• DataGridTable: the resize handle is its own data-slot span, so an end-aligned header cannot swallow the menu click - Docs.
• DataGridTable: aria-rowcount counts pinned extras and aria-multiselectable follows the selection mode - Preview.
• DataGridTableVirtual: rows and the header row are memoized, so a scroll frame renders only what enters the window - Docs.
• DataGrid: meta.autoSize columns reflow with the container down to minSize, and leave a dragged width alone - Docs.
• DataGrid: onRowCreate hands focus to the grid when a draft replaces it, and its click survives a multi-cell selection - Docs.
• DataGridPagination: the page-size select no longer clips 3-digit sizes, and page buttons carry accessible names - Docs.
• DataGridTableRowPin: bottom-pinned rows cast their boundary shadow upward - Docs.
• Combobox: chips in the spreadsheet editing example are outline badges with an avatar and a remove button - Preview.

v2.5.0 - 26 August, 2026.

New: Data Grid Spreadsheet Editing.

• Cell range selection with drag, Shift and Ctrl ranges and full keyboard navigation, opt-in via tableLayout.cellSelection - Docs.

• One batched onCellsChange write contract plus per-column meta.cellEdit parse, format and clear rules - Docs.
• Notion-style editing flow: built-in text and textarea cell editors via cellEdit.control, opened by Enter, F2, typing or double-click - Docs.
• Consumer editors keep the same keystrokes through onCellEditRequest for custom controls like selects - Docs.
• Full spreadsheet keyboard map: Ctrl+Arrows, Home/End, PageUp/PageDown jumps with Shift extension - Docs.
• ARIA grid semantics: role, row and column indexes, aria-sort, aria-selected and aria-activedescendant tracking for screen readers - Docs.
• Optional CRUD affordances: an onRowCreate add-row, getRowStatus row tints and getCellStatus corner marks - Docs.
• One column can absorb the resize filler strip via meta.fillWidth, keeping the grid full-width - Docs.
• New DataGridSelectionBar shell for bulk edits over row selection - Docs.
• Works alongside sorting, pagination, resizable and pinned columns; existing grids render byte-identically with the flag off - Docs.

New Free Components:

• New spreadsheet editing example: inline editors, a team member combobox, a date picker, quick add-row and a bulk edit bar, taking the Data Grid to 31 examples per base - Preview.

Fixes & Improvements:

• DataGridTable: cell borders no longer float against the resize filler strip when cellBorder meets columnsResizable - Preview.
• DataGridTable: resize handles no longer double the header separators when cellBorder is on - Preview.
• DataGridTable: end-pinned columns resize from their start edge, indicator on the correct side - Preview.
• DataGridTable: the viewport no longer draws a browser focus outline during keyboard navigation - Preview.
• DataGridCellSelection: the focused cell ring is a quiet 1px border-tone outline, and the editor keeps text exactly in place - Preview.

v2.4.0 - 25 August, 2026.

New: Shadcn Code Block.

• New Code Block primitive: Shiki highlighting, a copy button, wrap and expand controls, and per-line action groups - Docs.

New: Shadcn Cascader.

• useCascaderSelection() returns the resolved nodes, their ancestor chains, remove and clear - Docs.
• 20 examples per base, taking the registry to 21 primitives - Preview.

Shadcn Filters, rebuilt:

Fixes & Improvements:

• A wheel gesture over a preview keeps scrolling the page once the preview has nothing left to scroll - Preview.
• Data Grid sortFn: "auto" no longer warns and silently falls back on ordinary string columns - Docs.

v2.2.0 - 5 August, 2026.

Data Grid on TanStack Table v9:

• TanStack Table v9 is a foundational rewrite upstream: modular tree-shakeable features, state on TanStack Store, and a much faster core row model - Release notes.
• The Data Grid primitive now runs on v9. Tables are created with useTable({ features: dataGridFeatures }), replacing the per-table row-model wiring - Docs.
