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.

Safer Model Change Handling in SDK/Remote Sessions

The set_model and session-initialization code paths now verify model names against the allowlist before applying them. If a model is not allowed, the change is rejected and the user sees an actionable warning message instead of the session silently using an unexpected model.

Evidence

Updated onSetModel handler (search for "model-restricted-bridge-")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
