Beta ("Food of the Gods")
New zone and content will be released. "Corrupted Gardens" with bosses, new fashion (looks like Samurai armor), and cooking mechanisms. Also a new Chicken pet, and supposedly a mount or two. Beta signups are long passed, the beta/release was postponed and is just now starting.
#FakeNews
"Food of Gods" and "Corrupted Gardens" are completely different and seperate updates

And a bit more info.
Last announcement I can find stated Food of the Gods as being
- Cooking System
- Additional Fishing Content
- 200 New Bounties
- Story Questline Continuation
- Daily Login Rewards
- 2 New Fashion Sets
- 1 Pet
- 1 Battle Mount
...And more!
And is due for beta soon
Corrupted Gardens will be a new level 180 + zone with, if memory serves, 3 new bosses whose levels are still to be decided. This has been delayed and don't think there's been any updates recently about revised release dates.
Personally I wasn't convinced on the chicken pet. The reveal video felt like it was done as a bit of a joke, so I'm not sure that's going to be the genuine pet myself, but I could be mistaken.
