ASL errata and Q&A for A4 size paper 32

This is a compilation of official errata and Q&A from AH and MMP, plus unofficial Q&A. Before version 29, I did not include Klas's PerrySez compilation, but now I include it.
This file is formatted for A4-sized paper. There are other resources for 8½" x 11" paper, and with the changebars showing what's changed.
