Keynote presentation on JupyterLab confirmed, given by one of the developers, namely Vidar Tonaas Fauske (Simula Research Laboratory, Norway).
Number of recent registrations not commensurate with those for CHEP but may simply reflect the domain of work of registrants.

Belle II interested by a meeting with HSF on this topic.
License for DD4HEP: it is currently GPL, potentially a problem. Discussing moving to LGPL. This is a more general problem with AIDA2020.
- Also need to check the copyright owner. Would be good to have CERN but need to be checked with all the participants
- Most SW projects predate AIDA2020 and had a license chosen before the HSF discussions
