Mantine 9 requires React 19.2+, renames `Collapse`'s `in` to `expanded`, `Grid`'s `gutter` to `gap`, `Spoiler`'s `initialState` to `defaultExpanded`, drops `color` on `Text` and `Anchor` in favour of the `c` style prop, and changes `theme.defaultRadius` from `sm` to `md`, which is why the layout moves. evidence	2026-09-08 published
