No real big issues here! A broken json example, and the rest are comments. Let me know what you think.

Do we need to know what these contents are here?

I think I'll remove this line. Everything is explained below it adds nothing.

+There are two inband modes available:
+
+| Mode           | Description                                                                                                                                                                                        |


Suggested change

| Mode | Description |

| Mode | Description |

| --- | --- |

| `objects` | Sends the full state of all objects on the channel. |

This isn't a big issue, but you don't need to fill to match the size of the table. The above would do for the first 3 lines of the table. MDX will render it correctly either way.

Apologies, my IDE insisted.

Document the new `notification` inband mode for LiveObjects which notifies clients when objects operations are received without sending the full state data.

We now stop sending inband object state sync if an object is over the max maessage size.

Thanks Greg, I have read them and it makes sense. Do you want me to do the rebase? I don't want to merge just yet till the fix rolls out in production next week.

You're welcome to rebase to squash the fixup.
If not, I can do after the standup.

I'll keep ownership and I will release it when the changes rollout.
