Future of this meeting

  • We recognize as a community that each of us needs to adapt to current global events: improving the upstream open source libraries is likely to be slower.
    • No apology is needed if people take longer to respond to things.
    • Richard's role changed, so we need a change in host.
    • Fewer meetings and more async collaboration?
