There are two problems

1. missing baked physics track on the timeline -the option to show or hide it doesn't seem to exist.

2. we can no longer right click on the character to remove the vertex/baked physics animation in the viewport,

The only way to get rid of the recorded physics is to hit undo or delete the animation and readd it.

If you've made significant changes and moved a feature to another are, please add bubble help/tip to inform users where something may have been relocated or removed. Even having the tip redirect to a wiki or version change would be helpful.
