I believe it would be good to have the telemetry info elsewhere, in addition to the release notes (I suggest under "About us"). Let me know what you think and I will open a PR @valentinsulzer @agriyakhetarpal. This way we can release that as soon as the release comes out, and then we can edit the release notes without rushing.

Sounds good to me, thanks, @brosaplanella!

Given that Agriya opened the PR and he can't review it (but I have made significant changes) I am approving this. @agriyakhetarpal if you are happy with it just add a comment, but I think it would be good for @valentinsulzer to check as well.

We should hold merging it until the release is published.

[agriyakhetarpal]

Just a few minor comments, and we should be good to merge since the release is now out. Edit: and after Valentin approves the changes.

I want to make a LinkedIn post about the release so merging this now and we can always edit them afterwards.
