Sounds good. Do note though that it would be Qt 5.6 *beta*. I still think it makes sense to test our alpha with their beta. If things go well, then we know that we should stick with 5.6 and there is not much discussion to be had. If there are some disastrous bugs that we attribute to 5.6, then well the alpha has served its purpose and we will need to discuss whether they are bugs that will be solved by the final release of 5.6. I'm most concerned that there might be something that LyX needs to change on our end to adapt to 5.6, and if that is the case we need to know what that is as soon as possible. Any other opinions?

Agreed. Scott
