I see that the protocol id mentioned here is 766 but the protocol id in the latest beta/preview is 765, was it bumped in a newer internal version or is that a typo?

@GameParrot
As far as I know, v766 is the final version of the release protocol. I assume they probably forgot to bump up the protocol version in this week's preview because there are changes that weren't included in last week's preview (v1.21.50.26, v765). I know that the optional float mTrackingRadius/Block Listening Radius is not present in beta-26, but it is present in beta-28.

I also found a few errors in the changelog markdown file, probably caused by a copy/paste error. I strongly recommend not to copy/paste changelogs from previous versions before starting to write a new one, as this leads to confusion. (@oswaldolb)

  • changes to the PlayerAuthInputPacket::InputData enum are new since the addition of IsHotbarOnlyTouch(58), but not since the addition of StartUsingItem(53)
  • mEntityDefault and mBlockDefault (optional integers) are not mentioned (type: SharedTypes::v1_21_50::CameraAimAssistCategoryPriorities)

It seems like InputData in PlayerAuthInputPacket is still serialized as unsigned varint64, is that a changelog mistake or is it likely to change in the next beta/preview

It is a changelog mistake, from what I know
