REST API authentication changes coming soon

[Brad Bishop]

I just wanted to re-announce this change in a very visible way:

I'm not sure how to interpret the silence.  There will be some impact
to any programatic use of the current REST API when we make this
switch.  If you have issues with that please speak up so we can see
about what we can do to help ease the transition.

thx - brad
