Abstract: This is the promised sequel to previous reports from 2008 and 2014. Once again I’m immensely grateful to everybody who contributed potential errata to the “core” of TeX and Metafont, and to the wonderful team of experts—led this time by Karl Berry—who checked their input carefully and filtered it down to a list of issues that definitely demanded attention. According to our longstanding plan, I received that list on 31 December 2020. Let me just remark that, when I did the previous round of maintenance seven years ago, I had to deal with “more than two dozen potentially troublesome topics”. This time the number was more than 250(!).
