we won't let that happen, I think we owe it specifically to our early
supporters to provide them with continued support over a reasonable HW life
The OTA-4/OTA-5 incompatibility seems more like a bug than an architectural
/ platform issue (i.e. not comparable to gcc5) and wasn't a conscious
decision we took.
We are facing the interesting problem of shipping a stable product to
customers, iterating that product platform quite rapidly and then also
basing this work of the distribution and its ecosystem, which is moving at
an entirely different speed.
Instead of blocking the Ubuntu-sphere from moving to gcc5 at a time that is
right, we are accepting that the phone devel-proposed is seeing transition
issues, while keeping our shipping code base stable.
As Pat mentioned in his initial mail, we are working on unblocking things
asap, but the solution needs to be well crafted and thus might take a bit
before we are ready. It's in our own interest to unblock testing of
devel-proposed to keep in sync with the "upstream" development.
