- It appears you are working in the "8.1.x-dev" branch in git. You should really be working in a version specific branch. The most direct documentation on this is Moving from a master branch to a version branch. For additional resources please see the documentation about release naming conventions and creating a branch in git.
- No automated test cases were found, did you consider writing Simpletests or PHPUnit tests? This is not a requirement but encouraged for professional software development.
