What
Before uploading your working tree to a cloud session, Claude Code now refuses if uncommitted changes include paths shaped like Windows 8.3 short names, since such a name can resolve to a different file than it spells. The credentials-and-keys refusal can now also cite paths covered by a Read rule in your settings.
Details
An oversized starting file set can now be refused outright rather than quietly falling back to uploading only a bundle.
Evidence
which can open a different file than they name
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
