I should have been more precise so as not to suggest that Guillaume agrees with my next sentence (although I suppose purely logically, he does agree that < 5.5 is not worth to build against, he just thinks 5.5 is also not worth to build against). > >I would say it is not worth to build against any > >Qt 5.x less than 5.5. > > Well, I remember seeing a message on lyx-general reporting independently > some slowness that looked like the symptoms of 9731 so I would take it > into account. (Unless you mean "not ≤ 5.5" in which case I agree with you.) I meant < 5.5. I do not think 9731 is a show-stopper for a pre-release. I do think 5.4 has showstopper bugs for a pre-release. If Qt 5.5 were available (in the Ubuntu repos) for Liviu to link against, I think it would be interesting to discuss having a pre-release with it. We could get good feedback on potential complications for if we decide to link to 5.6 (e.g. in Ubuntu 16.04) when it comes out. I don't think 9731 would add so much noise to the feedback. For a final release, if the choice is between 4.8.x and 5.5 then I agree with what I think you believe, that 4.8.x is the best choice. Scott
