Google Plus Authorship

Tested up to: 4.7 < 6.8. The "Tested up to" value in your plugin is not set to the current version of WordPress. This means your plugin will not show up in searches, as we require plugins to be compatible and documented as tested up to the most recent version of WordPress.

Missing "License". Please update your readme with a valid GPLv2 (or later) compatible license.

Incorrect Stable Tag. It's recommended not to use "Stable Tag: trunk". Your Stable Tag is meant to be the stable version of your plugin and it needs to be exactly the same with the Version in your main plugin file's header. Any mismatch can prevent users from downloading the correct plugin files from WordPress.org.
