Euh, when we release a new version of MythTV does the previous release 
stop working for everyone who has it installed?

I have seen people mentioning they were still running very old version 
of MythTV without any problems...

It's their choice to update or not...

And then you have parts of the application most of the developers can no 
longer test because they no longer have the proper Qt version to test 
them...

If we start releasing things most us of can no longer test properly and 
end up crashing for people which have not updated their Qt version that 
too will minimize the user base...

I would even dare to say that it will shrink it more...

(I personally stop using some programs when they get too unstable...)

I agree that for a library or component you which is not as tightly 
coupled with the OS and application this is doable but I don't think 
that's the case with Qt and MythTV...

Take this with a grain of salt though because while I am a MythTV 
developer I am a minor one because of my (relatively) limited grasp of 
C/C++...

(I am responsible for the translation stuff...)

In the applications we release at work we update from time to time the 
libraries that we use but none of them are as tightly coupled with the 
OS and the application as Qt seems to be...

Talking of translations I see that the file format is starting to change 
with Qt 5 and I am not willing to bet they support using a translation 
file produced with the Qt 5 tools with Qt 4. Maybe they do but I think 
adding support for so many versions of Qt is a lot more than just 
condtionnally compiling...

You know fully well that's not the case...

Have a nice day,
