It would seam that between rc5 and the actual release one or two ui elements have inadvertently been adjusted.
1 - In the view entry screen the 'edit' button is floating up and slightly covering the 'mark as spam' button
2 - In the edit entry screen the 'update' and 'cancel' buttons are floating up and slightly covering the 'move to trash' and 'mark as spam' buttons
3 - In the form editor when you scroll down the page the 'standard fields' tab is floating up under the admin bar, only the padding under the label is visible below the admin bar.
