SOLUTION to the last puzzle
It's Themeless 21, and the last puzzle before 2021, so why not make it a 21x? I wrote a few versions of a 2020 recap for this post, but they all boiled down to "if you're a solver, constructor, streamer, tournament runner, or any combination of those, thanks for making the crossword community the way it is." So I'm just going to say that.
As far as this puzzle goes, shoutout to Adam Nicolle, Sid Sivakumar/Brooke Husic, Ricky Cruz, and Evan Birnholz for their excellent work on 21x themelesses, which very much paved the way for this one.
Also, the pdf has a new look—many thanks to Nam Jin Yoon's excellent new puz-to-PDF tool for the new layout!
See you in 2021,
