Hello @Gijsreyn, big thanks for this HUGE PR! This looks very promising, please give me/us some time to ingest it.
I will do my best to review it asap, and come back to you with questions or just approve it :)

@NowinskiK - I cannot understand why it's going to take so much time. Nah, of course, I'm kidding. I can totally understand! Take your time, and just hit me up if anything needs changing. There are 213 file changes with a TON of code :)

One small request: could you add one line to RELEASENOTES, please?
Otherwise, all looks good. A few tests don't work on my local machine, but I reckon it must be something on my side, as all runs on agents here look correct.

@NowinskiK - perhaps I don't have my glasses on, but the only ReleaseNotes.md I can find, references to a dead file. I have updated the CHANGELOG.md.

Haha, sorry, yes Sir! That's the file I meant. Thank you.
