• feat: #3451, #3452 dragging between grids now goes by how much of the item is over a grid (like jquery-ui's intersect before v6) rather than where the cursor is. Also make it possible to insert above a nested grid even when parent grid overlapps exactly.
• feat: #3356 auto-scroll triggers off the cursor nearing an edge (not just widget being clipped)
• fix: #3355 auto-scroll hands off to the outer container when a nested scroll container is pinned
• fix: #2729 cancel selector now matches elements inside a shadow root
• fix: #2728 drag helper drifts off the cursor when the page scrolls under a CSS-transformed containing block
• fix: #1959 update() refuses a move that would land on a locked item
• fix: #2666 iOS auto-scroll uses visualViewport, and un-bind touch handlers
• fix: #3418 preserve saved layout after cancelling a cross-grid drag- #3418 - thank you sameerdeolalikar
• fix: #2819 item not moved (to alt position) when colliding fails with an object
• fix: #3230 don't recompute w/h unless side can change (rounding errors)
• fix: #2208 cellHeight in vw/vh units converts straight to pixels drift issue
• fix: #3438 fix mode?: 'list' | 'compact' for h:2 and taller items (for #754)
• fix: #3443 Esc restores item (and pushed nodes) dragged out of its grid. Thank you @SinnerAir
