Hey all —
The only real change is that I removed the half-baked code using the wp_title hook in order to customize the page title, and instead the code was moved back into header.php and simplified a little.
I can call it half-baked because I was the one who wrote it. It interfered with some plugins and so we yanked it. Twenty Ten is also likely going to be picked apart by up-and-coming theme developers, and I didn’t want my inventive technique to gain any traction. (I’d much prefer we introduce a replacement wp_title(), which you’ll likely see in a future release.)
We also made a few minor changes to attachment/media styling and markup. Just some tiny improvements for a few edge cases.
There’s a ton of other small changes in there — style.css for example — but they’re all stylistic. (Ha! — get it?) We alphabetized the CSS properties because that’s what the theme guys like. ??
I see Mo already posted the full diff. If you’d prefer for your head to not explode, here’s the log of commit messages: https://core.trac.www.ads-software.com/log/branches/3.0/wp-content/themes/twentyten/.
Hope that helps.
