Client-related Items

Having a single 'source of truth' for others to track your progress on PeerDAS-related implementation would be quite helpful. If you could either provide a link (if one is not listed below for your team) or validate the link (if one is shown) for your team prior to Call 23, that would be great.

Great summary! May we have it updated on a regular basis somewhere here for example?

Thanks Katya!

Yep, I am hoping to get that part of the PM document updated this weekend. :)
