Cool! Very exciting to see the new functionality (and that we’ll have a good while to do the changeover) 
Especially great to see charge status included in the available information in the new API! This should result in some cleaner reconciliation between external websites and Patreon. currently_entitled_amount_cents may also provide similarly useful functionality – especially if any of these get updated more quickly than lifetime_support_cents does (last I integrated the V1 API, there was a next-day delay on updates to that field both in API and on Patron Manager).
Regarding currently_entitled_amount_cents, is there a kind of ‘entitlement_period_end’ datetime? I guess right now it’s always first of next month + grace period, but it might be nice to have this as a field in case other payment durations end up being available.
What are possible values for patron_status (is it an enum like last_charge_status?)
Also, still hoping to see some way to get member data from recently cancelled patrons (/any patrons who have currently_entitled_amount_cents > 0) per this thread.
