I sent an email in reply to dfaure, but it doesn't seems to have reached the 
mailing list.

There is a notes in the qt-copy patches saying if they are included in Qt 4.4 
branch. (or Qt 4.5, or none)

Only released version are suported by QtSoftware support.  
But the point is that, for the KDE 4.2 release, there will be no released 
version of Qt containing some fixes that are very important for KDE 
stability. (Hence my email)

Here is the content of the mail i sent previously:

The reason we don't release Qt 4.4.4 is that we don't have time to go 
thought all the usual Q.A. check. So i can only tell you what's in our actual 
tree and has been reviewed at least once :

I browsed all the patches:  here are those that are in our Qt 4.4.4 repository 
and should then be safe:


0256 is not related to the task it claims.   but IIRC we had adressed this 
issue but not with this exact patch.  I don't know wether this patch is 
required or not, but according to  Szymon Tomasz Stefanek  it solve a 
frequent crash in KMail with Qt 4.4.3

Patches that are in Qt 4.5: 
0203, 0238, 0242, 0250, 0257, 0261, 0263, 0264

Patch that have not been looked yet:
0216, 0225, 0226, 0231, 0234, 0251, 0255

0167: a similar fix is in Qt 4.5
0180: rejected
0195: I don't know if it has been reported
0224:  doesn't seems to have been reported, but the code is not the same 
0245:  I don't know if it has been reported
0248: A Modified version is in Qt 4.5
0249:  no idea but probably in
0258: has been rejected
