DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Permissions
A lead agent can no longer change a teammate's permission mode; those messages are dropped.
What's wrong with this entry?
Anonymous. No account, no email.
What
The in-process team runner used to let a lead agent set a teammate's permission mode over the shared inbox. Those messages are now dropped with a warning instead, unconditionally.
Evidence
dropping mode_set_request message: permission mode changes are never accepted from the inbox
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
