But you did ask in a branch of a thread about a Qt3D change, so I answered with respect to the part that I have knowledge about. > X updates are free do you really need support for anything older? > That's the perverse other side of the medal of free OS updates, and the > remark surprises me coming from the managing director of a company that sells > support... > > Linux has always been free, yet do people feel the need not to run anything > but the latest version? > The hardware to run the OS on is *not* free, and not all still perfectly > functional computers will run the latest software, esp. not if it's a recent > OS out of Cupertino. > > Anyway, the question was not about needs I feel, but about the official > stance, so that I know what to expect (and not to attempt) when I get to > updating the MacPorts Qt5 port. I was asking because I'm genuinely curious about the answer. I myself am using a Mac from 2011 that happily runs 10.10. I was not inferring that everybody should upgrade, but wondering how much of a need still remains to drive support for older flavours. As a director of a company that sells support I have to justify investments into supporting said older releases, so if there is no requirement or demand for it then we won't consider it. As it stands Qt3D has a minimum requirement of OpenGL 2 or OpenGL ES 2 but we don't have support for anything older than OS X 10.8 in the CI so support for say 10.7 can only be on a best efforts basis. Of course if somebody wants to pay for such support, then we would be happy to investigate this. Looking at the CI for qtbase for e.g. shows a similar story for OS X versions but I can't say what the official support is there.
