This release brings support for several long-awaited features, including support for expandable rows in Table, and window scrolling in Virtualizer. Expandable rows enable macOS Finder-like file trees by designating a treeColumn and rendering a chevron button within its cells. Window scrolling in Virtualizer enables virtualized collections to automatically scroll with the rest of the page. We've also added support for horizontally virtualized GridLists and ListBoxes! Finally, we significantly improved how we manage our dependencies – see the full release notes for details.
