0.19 counts active users differently; prior to 0.19, the count is only if the user posted, after 0.19, all interactions results in the user being counted as an active user. This inflated the active users hugely as all lurkers are counted.
The active users is dwindling. You can see the steep drop off prior to the change and a slow but continued decline after the update.
I do not know the reason for the number of posts falling off, but that doesn’t look healthy either to be honest.
