We want expand on that?

[godai78]

@Witoso - that's how I understood the comment on notion about this section. Do we?

[Witoso]

We can show in the update guide how to enable this version.

[godai78]

Like this?

It's ok! In my opinion, it wouldn't hurt to put the code block in the update guide; it saves one click for an integrator. But it's a minor thing.

[godai78]

Added.
