[Development] Changes to Qt offering

In essence the LTS patch release is a selection of bug fixes and security fixes (including update of 3rd party libraries). The bug fixes and security fixes will go first to dev and are cherry picked back to release branches.

After the change every release of Qt will look like a non-lts release for open-source users. Think of Qt 5.14 as an example. It was released in December. Today it received the first patch release. There will be more before next feature release is out. For open-source user Qt 5.15 will look just like Qt 5.14 does.

For commercial license holders the patch releases of Qt 5.15 keep rolling just like Qt 5.9. This is expected to convince some of the companies using Qt open-source to select the paid version. Not every company, but hopefully many enough.

An LTS gets rather more than just security fixes; an example of that
is compiler compatibility fixes.
Some of us, including Qt employees, backport bug fixes that are not
actual new features to LTS branches
