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.
The interactive "Enable auto mode?" prompt that appeared for some users has been removed. The strings "Enable auto mode?", "Yes, enable auto mode", "Yes, and make it my default mode", and "No, don't ask again" no longer appear in the codebase. Auto mode is now configured via settings rather than through an in-session dialog.
Evidence
Removed auto-mode opt-in strings (search for "showAutoModeOptIn" — absent from v2.1.208)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
