At least according to this:
https://www.citysignal.com/airbnb-regulations-nyc-january-20...
there are no substantial changes to the Law in type of rent and duration allowed, already you could not legally rent for less than 30 days a "whole" unit, the fact that everyone did it nonetheless is another thing.
An intentionally misleading statement from Airbnb. The law in question does severely restrict the class of permissible rentals (to owner- and tenant-occupied units), and will certainly bite them in the ass as far as this market is concerned -- but, as Airbnb is perfectly aware, it is not a blanket ban on short-term rentals at large.
Also, the law in question does not create new restrictions at all -- but rather creates a structure for enforcing existing restrictions.
For example, there are many multi-family houses where a family lives upstairs but can't rent out the downstairs apt.
