As outdated versions don’t receive any bugfixes (even critital ones), upgrading is usually the only option.
And : I really don’t know why the number of released hotfixes should be an indicator for the quality of the release. In 4.8 VR Support is completely broken (and was left in this state). Leap Motion support? The same. Why is simply not releasing fixes for critical bugs introduced in a new major version a good sign in any way?
Hotfixes are a good thing. The really annoying things are horror bugs which were fixed weeks ago internally, but are simply not released.
