Yes, we trust the marketing team to handle expectations.

And we need to start up a new Features page for 4.0.

Definitely stuff like Phonon and Solid.   The intention is we don't want anything that
causes major efforts to port, or to put things back to a compileable state.
We don't want any changes that require a couple days -> week of porting effort
any more past this date.

This is a close call.  I suppose the Core Devs really should decide.
By the spirit of what we had in mind, this probably should be in-place by 1 Apr.

This seems minor enough to be a 1 May thing.

I put the Qt 4.3 requirement at the Alpha Release stage because
I didn't know if it would be ready for the Subsystem Freeze on 1 April.

But the Core Devs can require it earlier than 1 May if so desired.
That doesn't break the milestone.

I guess it means that the API shouldn't change without a darn good reason
and without the Core Devs permission.  I think adding a method here
and there for good reason would probably be fine.

I am already busting on the kdepimlibs people.  
kdepimlibs will follow the same milestones and rules as kdelibs.

Comments from the kdeedu and kdegames release managers?

Thanks for the detailed response.
