It looks like I was wrong. I just got the hands today. My guess is that they are for 2025 contests (and oddly, I guess July, August and October contests).
I will start new threads for 202507 discussion, 202508 discussion and 202510 discussion, so that they are kept separate. Since the questions are copyrighted and haven’t been published yet, I don’t want to put them in a public post. I will send e-mails or GoA private messages to the people who have voted on at least one set of 2023 problems, but it is not intended to be exclusive. If anyone else wants to vote on them, let me know. I won’t get more than 202507 done today, others coming soon.
