New
- Drop a tab on a tab to group them. In the sidebar, let go of a tab, a selection or a pinned tile over the middle of a tab that isn’t in a group, and the two become a new group in its place. The tab lights up while you hover over it.
- Drag a tab out of its group in the top tab strip. With tabs on top, dragging a group’s tab past the group’s chip or its close button takes just that tab out of the group, and it lands where you let go. Before, it could only move around inside the group.
Fixed
- Settings sync no longer switches settings off. A setting one of your Macs had never stored, such as “⌘-clicking links creates tab groups”, synced as empty and turned the setting off on every Mac. A Mac without a value now has no say; a setting you switch off still syncs.
- Dragging a tab out of a pinned group no longer keeps the Mac busy. Ardia and Chrome’s tab strip kept rearranging the tabs back and forth, at about 145% CPU, until the app was quit. The tab now leaves the group once and stays where you put it.
- Reopened groups come back with their history. Reopening a closed group, or tabs Clean Up Tabs closed, brought each tab back on its last page with nothing behind Back. Each tab now keeps its back/forward list, as a single reopened tab does, even when you close it again or quit before you look at it.
- A pinned tab’s ⌘-click group keeps its tabs. After ⌘-clicking two links from a pinned tab and closing one, the other dropped out of the group and the next link started a new one. The group now lasts down to its last tab.
Smaller
- A tab dragged in the sidebar lands where you let go, even when the rows above it moved during the drag.
- Renaming a group while an extension moves or pins one of its tabs no longer undoes the move.
