Every 30 seconds my WP blog (using P2) throws up a little dialog at the bottom of the browser that says, "NaN new update(s). Go to homepage."
This appears with the latest Safari, Firefox and Chrome on a Mac, and IE 10 on a PC, and Safari on iOS (basically every browser I can easily test). Interestingly, I even see this when previewing the P2 theme in the wordpress.org theme browser.
Is anyone else seeing this? Is there a patch or fix?
