While we are on it:

Should we maybe also remove Quicktime, Realplayer and Director (which I think is the shockwave player)?

All of those shouldn't work in any modern browser anymore (and as the report notes, detection doesn't work in IE, so there should be nothing left)

i would create a pull request per Plugin

code changes look fine so far. Need to find some time to check it out locally and do some testing...

Probably a good idea, any thoughts @sgiehl @tsteur ?

I suppose should be fine. Not sure though re removing that data. You're basically removing historical data there of users. It may be fine as likely nobody looks at this anymore, but also feels a bit wrong.

Looking at the failing tests it seems all fingerprints changed due to the changes here. While that is fine for the tests and we can simply update them. I'm wondering if that is something we should adjust actually, as fingerprints for already tracked users might change after an update and they might be detected as new users then 🤔

Maybe we should use a default value 0 for gears in the config hash instead of removing it here:

Or is changing the fingerprints fine? (ping @mattab @tsteur )

Let's at least mention this clearly in the Developer Changelog? (in a section "Database Schema" or so?)

👍

@pebosi @sgiehl is there much left to do here?

I thought not.

👍 be great to get this merged @sgiehl not sure if something is missing

I'll recreate this PR with solved merge conflicts and fixed tests
