0.12.4 is End-Of-Line, but I've just asked them if they are going to support
0.12.4 in the future. Note that stellarium has low number of bugs and it
shouldn't be a big problem.

As far as I understand, it's about hardware support. Older GPUs are unable to run
stellarium 0.13.0, because they don't implement necessary features.

Qt is not an issue as far as I can tell (and probably it shouldn't be mentioned :) ).
It seems that Qt5 requires only OpenGL 1.3
(http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL), but if Alexander could
confirm this for me...

Alexander should comment on this, but I'll put forward my point of view.
As mentioned, 0.12.4 is EOL, they are not going to develop it anymore.
s-legacy would be there only to provide stellarium for older machines
that will be unable to run newer versions. It would never ever advance
its version.
