Lumeo 5.12.3 is on NuGet — Gantt bar labels stay readable across the progress fill in both renderers, DataGrid exposes FilteredRowCount/TotalRowCount/OnRowCountChanged and pins the expanded detail panel to the visible viewport; in 5.10.2 the customizer’s Menu Color follows the active theme and stays out of embedded previews (SidebarProvider.IsolateMenuColor); in 5.10.1 every composite uses Lumeo controls with sizing (no native select/input/date elements), the IconPicker popover scales with Size, DropdownButton/SplitButton chevrons render at 16px after hydration; in 5.10.0 a production field report is worked through end to end (Select search over composed items, OtpInput focus, Sheet swipe exit, DataGrid filtered-empty state and cell-edit commit/cancel, chart palettes, Scheduler culture titles), IconPicker joins the library, the date and time pickers gain Size, the Drawer gets vaul’s modal/dismissible split, close button and background scaling, and service-opened overlays can skip their exit animation; the 5.x line measures against shadcn’s live docs: control scale, radius scale, sidebar geometry, icon sizing, shadows and card spacing all land on shadcn’s numbers, Excel/PDF export lives in Lumeo.DataGrid.Export, and lumeo-classes.txt ships for consumers who run their own Tailwind build. See the changelog.

What’s new in 4.0

4.0 pairs a Radix / Base UI / shadcn parity audit with a library-wide correctness hardening pass. There are no API-signature breaks — see MIGRATION.md for the handful of behaviour changes.

• NuGet-free standalone eject — lumeo eject (or lumeo init --standalone) vendors components plus the whole runtime as source, so a project compiles and runs with zero Lumeo / satellite PackageReference. Proven across all 164 components.
