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.

SSL/TLS Certificate Telemetry

New telemetry tracks SSL/TLS certificate configuration for debugging connectivity issues.

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