Now there is also a CHANGELOG.txt in nightly builds 📰
@tzirechnoy Thats ok as it would work for you. And as @stormi mentioned, there is no difference in binaries except the ones he mentioned. So you would not see any execution differences.
Thanks for that.
@maxcuttins There are two packages. User level blktap driver that you referred blktap and a builtin kernel driver blktap2. Said patch is against mainline kernel as additional driver.
You still need to have user land blktap from https://github.com/xapi-project/blktap
There are instructions lying around https://xcp-ng.org/forum/topic/122/how-to-build-blktap-from-sources/ to build user land blktap (its without patch).

No believe me. They don't have it. But they have a huge farm of test hardware. That's why they don't need an emulator…
