What
On Windows, the check that spots network and device paths in Bash command arguments now strips --flag= and -f= prefixes repeatedly and re-checks what is left, and recognises \??\ NT object-manager paths. Off entirely on other platforms.
Details
- Path checks in Read, Edit and NotebookEdit, plus the file-path display component, moved from ad-hoc
\\///prefix tests to shared helpers that also cover/net/<host>autofs paths. - NotebookEdit lost its shortcut that accepted UNC paths without further checks, so those paths now go through the
.ipynbextension check like any other.

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