Already released distributions are in package / version freeze. No new packages will be 
introduced into standard repositories.
Ubuntu 10.x doesn't contain any version of Calligra at all anyway (only KOffice).

New major versions of applications do not get included into already frozen standard 
repositories anyway (Firefox and Chromium due their development cycle are usually two 
exceptions).

If you want to discuss deployment of packages by distributors, contact them.
I merely explained the situation.

No Calligra included.

Yes, they may include them and never upgrade them within a distribution version to a new 
major app release. Ubuntu 12.04 will have Calligra 2.4 in its repos and never upgrade it 
for 12.04 to a new Calligra major version.

This mailing list is not the place to discuss how distributors should behave.

Again: This mailing list is not the place to discuss how distributors should behave.
Fact is: Once Qt 5 is released, Qt 4 reaches End Of Life (maybe Digia will continue to 
support the closed source version of Qt 4 longer). Still depending on Qt4 for new Calligra 
releases after summer 2012 would mean to force users to install Qt 4 and potentially 
expose them to bugs in Qt 4 that may never get fixed.

Again: New Calligra major versions won't get included in existing standard repositories 
anyway.
New major version would be required to be obtained via an unofficial 3rd party repository. 
That repo may just as well hold Qt 5 / KF5.

You still do not get that there is not and never ever will be again a software called 
"KDE".
Plasma Workspaces 4.8 will already replace some components with QML counterparts.
KPW 4.9 will depend on KF5 but it won't be a complete rewrite. If you want to discuss 
Plasma's version numbering, do that on plasma-devel, not here.
All I did was to tell you what Plasma developers discussed. I'm not a Plasma developer and 
calligra-devel is the wrong place to discuss Plasma development.

No Plasma Workspaces 5.0 release is planned at the foreseeable future.
The upcoming summer release will be 4.9 and based on KF5, just as KOffice 1.x were based 
on different Qt and KDE libraries.

If you have problems with that, discuss that on plasma-devel.
I'm just the messenger.
