Irregular shaped icons get a background shape. link
Menus now can optionally feature icons, making it very Windows-like
Menu bar can be set to opaque/translucent with reduce transparency.
Reduce transparency is buggy and can cause flickering in the first beta
Third-party menu bar items can now be removed.
Folder colours pick up the colours of previously tags, and works in tandem with this functionality (as expected)
Spotlight – Spotlight can now search clipboard history, including items from Universal Clipboard.
Clipboard history not present in beta 1?
You can assign Quick Keys to individual actions, allowing you to add a reminder by typing "ar" into Spotlight, for example. Not yet in beta 1?
Suggested apps listed in Spotlight include iPhone apps, which are opened with iPhone Mirroring. Spotlight can also now search through an active app's menu bar items.
Background apps – macOS now notifies you via a new popup when apps attempt to run a daemon after they have been closed. You can "Always Allow" the background process to run or you can deny it permission.
PS5 controller options – A new Game Controllers settings menu lets you remap and customize PlayStation controllers, right down to the level of haptic feedback and even the lightbar colour.

Unified Safari URL Bar – Safari no longer offers the option to unify the tab bar and the address bar (the Compact tab layout setting), perhaps because it wasn't popular with users. Apple could always reinstate it in a later beta version.
Safari now has a transparent address bar, and colours from webpages shine through the browser's main toolbar.
