Wow, a lot of significant improvements! Thank you!

Considering that you updated the docs too, what do you think we merge this PR to the release/1.7.0 branch, so the new docs will be published at the release date?

That would be great. But how does that work? Do I need to do something?

Just changing the base branch of the PR.
I've just done this :)

[ematipico]

It seems there are a bunch of conflicts. I suggest reverting the change and point that to main again. It's not the end of the world if the docs will stay not synchronized for a few days.

[Sec-ant]

I can resolve the conflicts or revert the base to main. Or @Conaclos can do that if he wants. Each is ok by me. But currently I only have my phone around and have to go to bed now.

Please leave a comment to let me know if I should do something and I can address them my time tomorrow.

[Conaclos]

@Sec-ant Feel free to address them.
