A few things have changed since the beta of 4.3 regarding the Mon-MainWP Changes on the overview page.
The issue with the number of items has been fixed, but now the pagination is incomplete. It’s showing 303 items over 31 pages, but the pagination section takes to much space out of the screen and is unreachable.
This happens as well with other dashboard widgets like Monitors.
The default sorting was old to new, while it says “latest changes”, so new to old would be a better default. But it looks like the sorting is remembered, so I don’t think that’s more than a minor issue.
