I included the UHO 2022 openings to the download-package. But the main new thing are the Chess324 64x openings-sets.
7 different openings concepts: Chess324 64x, Drawkiller V5, No Black Short Castling V2, No Black Castling V2, White One More Pawn V1, White One, More Move V1 and Unbalanced Human Openings V3 (2021) & Unbalanced Human Openings 2022

Chess324 is a subset of DFRC, with kings and rooks on their "normal" positions of classical chess (kings e1/e8, rooks a1,h1/a8,h8). So, in Chess324 no special chess-rules (castling-moves!) are needed. DFRC is FischerRandomChess (also known as Chess960) but including non-symmetrical positions of the pieces of white and black...
Chess324 64x means: All Chess324 positions combined with 2 single-step pawn-plies (example 1.a3 c6 or 1.e3 h6 and so on): 64 of these 2 single-step pawn-plies are possible, so there are 324 * 64 = 20736 possible different openings for evaluating.
The testing results show, that the classical Chess324 opening set has a pretty high draw-rate. My Chess324 64x sets give white a measuerable advantage, so the draw-rate is much lower. And all of my openings sets have at least 500 lines, which is enough for a 1000 game head-to-head competition (the classical Chess324 set contains 324 lines, only).
Here some of the testing-results (Chess324), more testing-results on my website. All played test-games (nearly 42000) are stored in the download-package...
