I did it! I upgraded to WordPress 2.0 tonight. Do let me know if you find anything amiss, for it was suspiciously easy to do. There are (hopefully) no changes on this side of WordPress, but on the administrator side many things have changed: it looks very clear and bright, and I’ve already noticed that the preview function in the “write post” screen applies my stylesheet — very good.
Update: mmm, just tried to add a new link – it shows up in the clear and bright administrator screen, but it refuses to manifest itself on my weblog… Perhaps I should reserve tomorrow evening for looking into WordPress 2.0 bugs?
