Just a quick note: as you know, API v1 was officially scheduled to go
offline on November 1st, and support for it ended on that day. You
may have noticed that that didn't actually happen; we needed a few
weeks to fix some last-minute monitoring and internal dependency
issues.
So, the effective end date for v1 was today. If you were still using
v1 for anything, you'll need to port to v2 immediately.
thanks
