Oddly enough, when I tried to start this thread, Opera crashed on me. Strange.
Anyways, I was going to point out that it seems much more stable and wonderful, but maybe I should hold my tongue
maps.google.com does seem to work better in the latest version tho (they've made changes to the protocol that it uses and it seems to be working great).
Other than that, no major differences. The changelog was rather extensive however.
