This was always the case until now - except that recently the changes 
are very frequent and more profound. Do you expect continuing profound 

If so, consider slowing down the release rate to allow us to keep up. 
And if the changes kind of settle down, then it will be tolerable again, 
like it was until v52.

Haven't seen requests for special documentation for every id change... 
more like, when it seems every other thing has changed, we might be 
grasping in all directions for something to hold on to.
