Did Puzzle Rush just get a lot harder?

I've noticed two things in the last couple of days:

1.  Puzzles seem to have gotten harder in PR. 

I used to blow through puzzles up til close to twenty and now I'm getting stuck at 500-600 level (11-12) puzzles.  I'm getting "1100" range puzzles that feel as difficult as 1800+ level ones from tactics... Something's changed since the reset.

2.  Tactics also seem to have gotten harder.

I'm getting "1800" puzzles that 0.0% of people have solved and are harder than the 2200+ puzzles that I routinely figure out.  I suppose they probably introduced a bunch of new ones that they're testing out but the old "1200" testers they had before didn't really affect your rating.  These do.

Anyone else notice this?

This is one of those "1800" puzzles I'm talking about.  Note the 1000+ attempts and the 7% solved.  That seems like they got the data they need to give it a more accurate rating.

White to move after dxe5 if you want to try to solve it.

Here's an 1800 I got yesterday.  Note the new rating (way out of my range) and the slim success rate.  I guess it's just the testing process for new puzzles.  I'll stop complaining now.
