What

The sandboxed network proxy now copies a request body only for methods that carry one, or when a content-length or transfer-encoding header is present, and tears down both streams when a request is malformed or denied. Deny messages were reworded and encrypted-tunnel requests are now filtered against a decoded command name.

Evidence

denied by sandbox policy

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