+
+Last release was almost 4 years ago and the repository with outstanding issues and pull requests seems to be abandoned by the maintainer.
+
+In addition the sole maintainer account may be abandoned that may represent account takeover risk.
+
+Current outstanding issues include vulnerable dependencies that all together may mean that security issues may not be addressed now or in the future.
