+Subject: [PATCH] Replace semantic_version with packaging
+
+Use the "packaging" package instead of semantic_version package to parse
+Rust version and spec. Packaging is used by setuptools to parse version
+strings and specs.
+
+This also solves a deprecation warning with semamtic_version. The
+partial argument to Version() has been deprecated.
