Quick brain dump on this topic before I go off for lunch :)
Alexandre is tracking a lead from Didie in to the Unity migrations
system, should handle pinning the icons for upgrading users without
any Unity code changes.
Support for preauthorized domains is landed in libunity-webapps. We
need to finish a list of domains and add them to the key, this is
being tracked here:
https://bugs.launchpad.net/libunity-webapps/+bug/1046477
Support for per domain app generation (amazon) and homepage/domain in
every app has landed in webapps-applications.
After this it will just be a matter of uploading the packages and
ensuring they get pulled in!
Thanks,
Robert
