Hi Alejandro,

Moving to a new Qt release takes quite a bit of effort and our 5.2 branch is getting into a pretty good shape. Jumping to 5.3 would mean a lot of additional sanity testing and based on the outcome of that, adapting to changes and bug fixing. It would delay the update by an unknown amount of weeks or months. The 5.2 branch already contains stuff which we really want in the platform (like the improvements to QtQuick) and we want those sooner rather than later. We'll get around to 5.3 and also 5.4 eventually, though. Just not right now :)

Very true, an we've taken steps to get away from that situation. For our Qt 5.2 branch, we still have a lot of patches, but all of these patches were upstreamed to 5.3 and 5.4 before they were back-ported into our 5.2 branch, so we're converging rather than diverging.

It is a valid point, and do we want to stay fairly close to the latest released Qt, preferably without patches. But since we also have a platform on top of Qt, there is some latency in getting there.

Hope that answers your question.

cheers,
Gunnar
