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.

UNC Network Path Blocking

What

Windows UNC network paths (e.g., \\server\share) are now explicitly blocked in the sandbox path resolver, requiring manual user approval.

Details
  • Previously, UNC paths could potentially bypass sandbox restrictions
  • Now returns a denial with the message "UNC network paths require manual approval"
Evidence

UNC path check in sandbox path resolution (search for "UNC network paths require manual approval")

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