Smugmug web service ported to O2 : Host authentication required

[Gilles Caulier]

Hi Thanh,

We have the second student working on the manual icon-view sorting project
who advance well and have completed a first stage of the project as the
code is typically read for testing as beta by end users.

We plan to release an official 6.0.0-beta1 version in a near future, with a
back-port from the student development branch to master.

The goal is to provide an official test version with a release announcement
including new feature to test, and of course to catch user feedback quickly
in goal to stabilize new implementations.

What do you think about your project ? Some O2 implementations can be ready
for a beta stage ? Of course, this will include to back-port current code
from your branch to master.

Best

Gilles
