Dear all,

as I have unfortunately mixed up things in the last newsletter, the December preprints have been omitted. A single person (out of 1200 recipients) had read to the end to the newsletter to remark this problem, so I conclude that you all had a lazy Christmas holiday ! You will find a double share of preprints this time to take a healthy start in 2022.
