Short description of error
The Undo History used to have the most recent entry at the top-left of the list. Now it's the other way around, and it's not in the release notes so it seems unintentional.

Exact steps for others to reproduce the error

• Add some cubes
• Edit->Undo History
• Is now a sub-menu instead of a pop-up window which is nice, but entries are reversed compared to 3.0.
