It has all the features and functionality expected in a modern CMS. The current stable version of DotNetNuke is 9.11.0, released in September 2022.
DotNetNuke is mainly known for its extensibility, security, and ease of use. You can use the CMS in its barebones format, like WordPress, or extend it with addons. DNN is suitable for both small and medium-sized websites but can be developed to support large multi-site implementations.
