Tried this new release has "major" change for the tabs with if you have "tabs" on. Namely
1) Squared off like Windows Metro (?)
2) The default colour is orange with "black" where there are no tabs !
Not sure about 1 but definitely don't like 2). Tried the "Themes" and while the tab color is better really don;t like the light on dark text.
Have done back to the previous version 10621
