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.
Background sessions on Windows now detect UNC (network) paths in the working directory and emit a warning that such paths are not supported and will be neutralized. This prevents silent failures when background agents are spawned with a UNC-path CWD.
Evidence
UNC path check (search for "warning: background sessions do not support Windows network (UNC) paths")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
