Changes between Version 1 and Version 2 of Ticket #50448, comment 17

v1	v2
7	7	So if 10.y were to be the latest version supported officially, users of an earlier versions 10.x would have a 10.x tree that they'd install as a default tree ahead of the main tree. For example, port:audacity could provide 2.1.3 in the 10.6 through 10.8 trees (last version to build without C++11) or to use Qt5 as an example in a more general context: port:qt5 would be providing Qt 5.8 in the 10.9 tree and 5.10 in the 10.10 tree (instead of having a bunch of qt5x ports in addition to port:qt5).
