WotC has published the latest Sage Advice column from D&D developer Jeremy Crawford, along with an updated errata file for the Player's Handbook reflecting changes to be found in the 6th printing of the book (there are about 10 new errata items from the 6th printing, plus the ones from earlier printings). The Sage Advice features various barbarian class features, as well as some combat clarifications.
MechaTarrasque said:There is a new, barbarian and bladesinger-heavy sage advise column on the D&D website.
Neither frenzy nor the GW feat gives you a second (or additional) bonus actions.
Spiked armor is worn, thus you can't duel wield with it.
You can two weapon fight with bladesong.
You can't take the same fighting style twice, so the fighter/ranger multiclass doesn't get to double down on archery.
