What do you recomend as reading material for someone that was in college a while ago (before AE modes got popular) to get up to speed with the new PQ developments?

If you want something book-shaped, the 2nd edition of Serious Cryptography is updated to when the NIST standards were near-final drafts, and has a nice chapter on post-quantum cryptography.

If you want something that includes details on how they were deployed, I'm afraid that's all very recent and I don't have good references.
