For project under GPLv2 there’s really no difference, as all parts of Qt that were available under LGPLv2.1 are still available under GPLv2. So you can continue to use Qt for your GPLv2 project as before.

This is only true if you combine these into a single work. This means, if you directly combine Qt code with code under the above licenses. If you use Qt as a shared library, it’s possible to keep LGPLv2.1 libraries in your stack. 

If you use libraries under both v2.1 and v3 in your application, you simply need to adhere to the license requirements of both licenses.

Cheers,
Lars
