v8.0.0

This is a major release with significant breaking changes. It modernizes the library's internals, drops styled-components, and requires React 18+.

Breaking Changes

React 18 minimum — useId() and useTransition() are now required
styled-components removed — replaced with plain CSS (DataTable.css) using rdt_ class namespace
CSS custom properties — theming now uses --rdt-* CSS variables via the theme prop; ThemeProvider is replaced by StylesContext
clearSelectedRows prop removed — replaced with an imperative ref API: useRef<DataTableHandle> → ref.current.clearSelectedRows()
TableProps split — broken into SelectionProps, PaginationProps, ExpandableProps, and SortProps
filterValues / onFilterChange — now accept a structured FilterState object instead of a plain string
deepmerge dependency removed — replaced with inline mergeDeep<T>
Build output changed — rollup replaced with tsup; ships ESM + CJS + DTS; CSS is inlined into JS by default (no separate CSS import needed unless using the ./css export)

Column visibility — useColumnVisibility hook with show/hide support
Column filter redesign — FilterState supports multiple operators, conditions, and AND/OR logic toggles; filterType prop specifies input type per column
Column resize — extracted into useColumnResize hook
Skeleton loading — built-in skeleton load state
Middle-click row interactions — support for opening rows in a new tab
Row selection — keyField support with selectedIdSet for improved performance
HeadContext / RowContext — eliminates prop drilling in DataTableHead

TablePaginationFooter and ColumnFilter components added
DataTableHandle type exposes imperative clearSelectedRows() API

Jest + jest-styled-components replaced with Vitest
