Official Vs Community Plugin

Any plugins which are updated with the XLR/D version numbers or close to it are official and rest are a community plugins.

Official plugins are updated regularly as per the current software practice and is tested against any code change or update.
Community plugins are created by consultants, customers, and sales engineers on the fly to meet some requirements. Community plugin doesn’t get updated that often and requires the customer to manage moving forward or reach out to CSM for consulting or raise an issue in community Github.
