If I read the release notes correctly, the title block will become an actual block, with the permalink only available via the right-hand panel. That's a bit annoying for me (your mileage will vary, of course), as above the title block seemed to the most appropriate place for it to be, and only visible when you wanted it. I'd just tidied up that Document section by disabling the Permalink tab, now I'll have to reinstate it. Ho hum.

Apart from that... who are all these people crying out for gradients? Was there a great social movement somewhere, and I missed it? ;-)
