Ask HN: Did Amazon KDP change the number of books published per week?

I'm a bit confused about something I've noticed this week. Up until now, I thought that KDP allowed for the publishing of up to 10 new titles per book format per week. Now, in a week when I've published only 2 books, KDP is already telling me that I have reached my weekly limit of titles created.

Did amazon recently lower the limit of books published per week from 10 titles to 2 titles per book format? I'm seeing talk of it, but wanted to see if others are seeing this on their accounts too or if it's just me. Personally, I didn't expect it after publishing only 2 books this week. Is this a permanent change or is Amazon testing this out?
