[Interest] Regarding selection of stable version of Qt

I am working on a new development project with a custom board that uses a TI am335x.  We use Qt5.2.1 and it works great.  When we started we were using 4.7 but switched over to 5.2.1 to get all the good new features.  I personally would not recommend Qt 4.x if Qt 5.x is an option.  Good luck!

Hi Sonakumar,

Qt 4.7.1 is stable, but that's about the only good thing with it. 
Whoever is saying this needs to update their views.

If you want to stay with the 4.7 line, you should at least move to 4.7.4, as this fixes several security problems.

Personally, I would not consider the Qt 4 line for a new project. It's a dead end, and only 4.8 receives some security fixes.

If you need a stable line, I would suggest the latest Qt 5.3 release.

"TI board" says nothing. There are so many that it's impossible to say if Qt supports it or not. But very few architectures have been dropped since 4.7, so there's a very good chance it will be supported. Unless you have a very old C++ compiler for the board.

I hope this helps,
