XD 33 came out this week.
XD 32 introduced multiple flows in the prototype mode. The homeArtboard and isHomeArtboard APIs were modified to not break in a multiple flow scenario.
In XD 33 we have a new flow API called flows to allow developers to get flow information (name, homeArtboard, and URL) for each implemented flow. Read more about it here.
There are no breaking changes anticipated. The changelog is located here.
