To Do: add links to the items below, e.g. to labelled issues, minutes, etc.

  • Review editor's sync call minutes and actions
  • Review (and comment on/close) security-related issues in other repos
    • TD
    • Arch
    • Profiles
  • OAuth2 flows in TD...
    • When and where do non-client flows make sense?
      • The client flow needs a confidential client, and browsers do not qualify (need mutual auth?) so...
      • relates to the example used in the TD spec for non-client flow, i.e. maybe we recommend that there needs to be at *least* a client flow but other flows can be allowed as well for affordances that make sense to use directly from a browser.
    • We may have to put implicit and password back into the TD1.1 spec for TD1.0 compatibility
      • But then need to add text saying that these are deprecated and SHOULD NOT be used (and will be removed in TD 2.0)
  • Profiles Security
