[Interest] [Development] Windows 7 support will be dropped in Qt 6

[Roland Hughes]

I seriously beg to differ.

In America "upgrades" and field patches have a completely different 
certification path than "shiny new device." What has to be certified is 
based on the extent of the changes and how well the FDA documentation is 
filled out.

That OS/2 Qt3 medical device I get an email about ever 18 months or so 
continues to get enhancements. Changing to even Qt for or Linux would 
push it to "shiny new device" depending on the assessed risk level.

A patient monitor like this one

Has a completely different risk level than say, an infusion pump.

I have worked on products that just added new features to existing 
lines. In America it happens all of the time.

Cie who do that, did it wrong, you have to ensure your software will run and you maintaint it, but in no way you will add any new features (you will need to certify again!). You keep a system images that can recreate the exact same output (OS, build tools, ...), you patch the bug that's all you should do. New features will be done into a new system that will need to be certify all over again.
