Release Notes

EmbarkStudios/cargo-deny (EmbarkStudios/cargo-deny)

v0.18.4

Compare Source

Added

• PR#779 added the --metadata-path argument to use a cargo metadata JSON file instead of calling cargo metadata, resolving #​777.
• PR#782 added sources.unused-allow-source to allow configuration of the lint level when a source is allowed but not used by any crate in the graph, closing #​781.

Changed

• PR#786 changed the license check output. / is no longer corrected to OR, and if the license expression is found in the package's manifest, that span is used in diagnostic messages instead of the synthesized manifest.

Fixed

• PR#786 resolved #​784 by updating spdx to a new version that forces all GNU licenses to be exactly equal when comparing license expressions to licensee expressions, which is incredibly pedantic, but means the license comparison is entirely in the hands of the user so that I no longer have to deal with GNU licenses.
