The patch notes contained a lot of changes that none of us was truly expecting, most of which (but not all, of course) are being generally well-received. The biggest shock is that the patch will include the first new PvP arena in years. Also included in the notes was the announcement that the devs have been busy revamping several of the low-level Starfleet missions to improve their look as well as their pacing.
I've had the opportunity to jump on the Tribble test server to check out some of the revamped missions. Of the 12 missions on the list, I've played four: Stranded in Space, Kuvah'Magh, Researcher Rescue, and The Ultimate Klingon. Many of the screenshots are from the updated missions, so beware -- there be spoilers ahead!
