I may be able to release the update 201801 this weekend, I am not sure.

Of course suggestion about what to include are welcomed.

In the meanwhile I use the opportunity to as Eric Rechlin of hpcalc.org whether his torrents are somehow near completion.

He estimated to be able to release a first one in Q1 2018 if I remember correctly. I am still excited at the idea because redundancy is needed to hope for the survival of all the contributions.
