User blog comment:Jimeee/Skyrim 1.9 beta update adds Legendary difficulty and raises level cap (Updated Apr 8th)/@comment-5792868-20130318095538/@comment-3428817-20130319155628

@Jackdc: Dude, as far as I know, there was no level cap increase when Dawnguard came out. The level cap is still 81 (which is an odd number to pick for a level cap but that's beside the point) and if I've read this blog correctly, this TU will lift the lvl cap completly.
