Hey folks 
!
Re: the include fields, I’ve started another post here so we can keep the discussions separate: New Optional Include Field Parameters in the Confluence Cloud v2 REST APIs
But to answer your question @scott.dudley - yes! We’re planning to bring the changes to more content types. We’ve released the change for pages and blog posts first so users can have a look and see if it fits their use case. Let us know of your thoughts in that thread.
Re: the deprecation dates, our team will be working through the next steps and will provide an update once we can provide a more accurate date.
