This requires creating a new version of the app tied to the new framework,
the old version will continue to be available for phones not yet upgraded.

Not sure where the store stands on supporting multiple versions of the same
app.

Again, two copies if I understand the question.

We decided not to support multiple base framework versions in a single
click, mainly as the app_id corresponds to a single apparmor profile which
correlates with the framework level.

We do support specifying multiple frameworks but only in sensible
combinations using the same base. For example:
"frameworks": "ubuntu-sdk-14.04-qml, ubuntu-sdk-14.04-html"


 4) Supporting upgrades of phones(?)

Of course? The phone would get an upgrade. Because of our rules on not
breaking API, the old app works on the new upgraded phone.  Then a newer
version of the app which uses the new framework and apis is shown as
available. Again the store needs logic added to support the idea of
multiple versions of the same app.

I will defer to Beuno for more details.

Cheers
