Qt5 or Qt4?
We all expect questions in the future about Qt5.
There will be a twilight zone : some people remain on Qt4 and others go straight ahead for Qt5.
But people tend to forget telling us what version they are using. So I tought it would be a good idea to have a way of distinguishing this for instance in the "post a new topic" page where you could mark some radiobuttons and without marking it it is not possible to submit your post.
What do you all think of this? Or are there better places to do this?

It depends on the requirement too. I read somewhere that Qt5 won't be supported for Symbian devices. If this comes true as rumored then mobile developers have no option but to stick with Qt 4.
Yes, knowing the target is usefull and sometimes required. In your case you could post a question about symbian and mark the Qt4 radiobutton.
Corrrect me if i'm wrong but symbian users have a good habit telling us they are on symbian when posting questions.
Maybe it would be better to use subforums for distinguising targets.There has been a discussion in the past and the decision was to make only one mobility subforum not one for meego, symbian and so on. I think that's another discussion....that has been dealed with and is closed.

Not sure it is really needed. If we return back to period when Qt3 and Qt4 were living together then all who posted about Qt4 wrote about version. And Qt5/Qt4 difference is not so much as Qt4/Qt3 was, so part of problems will be common for both versions.

I just waiting for scene graph, and it's 2.5x speed up for QML. @QtK, is it true that Qt5 won't besupported for Symbian devuces?

Yes that's true. but some people will remain on Qt4 for a while when most of us are using Qt5.
Then we will get questions about Qt4 while we expect it to be about Qt5. I remember from old times quiet some posts asking if it was about Qt4 or Qt3.

True, people will make such mistakes. Lets deal with the issues if they arrise. As Denis already said: the differences between 4 and 5 will more like those between 2 and 3 than like those between 3 and 4. That means that there are less places where differences may be an issue. Otherwise, tags, [Qt4] tags or specialist (sub) forums may be a solution.
Lastly: just by asking for the relevant version, you get points! What more could you ask for? ;-)
ok, I get your point. ;)
EDIT : in this context this is double.
I didn't know Qt5 and Qt4 look like one another so much.

The plan is, that as long as you don' t use anyting marked depricated in Qt4 (including Qt3 support modules and -methods, of course), your Qt 4 sources should compile with Qt 5, perhaps after running a script over your sources to do some automatic changes. This will only be broken if that is needed for really important improvements.
That's interesting to know.
