So far as I have tested, all themes appear compatible with WordPress version 2.7 in their current versions – if you do find anything, please let me know. There may be a few advanced features unavailable as yet, due to the relevant template tags not yet catered for.
The question of whether you want to run 2.7 or not, I think is an open one – there seems no change in the overall situation following 2.5 and 2.6, just different admin bugs – image rollovers on the admin submit buttons aren’t right, Firefox 2,3, 800px resolution and the media uploads aren’t happy with Windows-version PHP. Linux, good, but that isn’t everybody, unfortunately…
