Add a new "Inspect Manifest" pipeline #284

CHANGELOG.rst

@@ -4,6 +4,11 @@ Changelog
 v31.1.0 (unreleased)
 --------------------
 
+- Add a new "inspect manifest" pipeline to resolve packages from manifest, lockfile,
+  and SBOM. The resolved packages are created as discovered packages.
+  Support PyPI "requirements.txt" files and AboutCode ".ABOUT" files
+  https://github.com/nexB/scancode.io/issues/284
+
 - Add a new "check vulnerabilities" pipeline to lookup vulnerabilities in the
   VulnerableCode database for all project discovered packages.
   Vulnerability data is stored in the extra_data field of each package.
