All sounds reasonable to me

> In Hardy, we put KDE 3.5.10 first in backports and later in updates. IMO,

> backports Qt 4.4 to Hardy and it did not go well (lots of problems with
> non-KDE apps).
> For Intrepid, we released with KDE 4.1.2 and put 4.1.3 and 4.1.4 in updates
> (via proposed of course). We also put 4.2.0 in backports. All of this
> went well and we had very good upstream support for dealing with
> regressions in the point releases.
> I think we mostly expected this to be the model for the future.
> In Jaunty, we got a bit cross-threaded between Qt and KDE expectations. Qt

> have some minor regressions that are not supported by upstream. Currently
> updates are limited to PPAs.
> We know that KDE 4.4 will be developed with Qt 4.6. These will be our

> Based on the experience with 4.1 and 4.2, I'm comfortable with pushing 3rd

> I think that given the pace of Qt/KDE updates it will be rare to have a
> good mix available for backports.
> Here is what I propose:
> New KDE versions (e.g. 4.3/4.4) only in PPAs.
> Micro-version updates for KDE to -proposed/updates if we have upstream

> Micro-version updates for KDE to backports otherwise.
> No backports of major Qt updates.
> I think we need to do some experimenting with the idea of micro-version Qt
