# What's New in 3.0.1 Properties weren't being read correctly from the `server.json` file. If you have been using `server.json`, please double check the format of the file here in our docs: This fix will make this functionality work as expected: ``` server set web.http.port=8000 server start ``` ## Upgrading If you already have 3.0.0 then this fix only affects the CFML bits and is very easy for you to install. Simply run this command: ``` upgrade ``` If you're still on CommandBox 2.x, check out our [3.0.0 release announcement](https://www.ortussolutions.com/blog/commandbox-300-final-released) to see the cool new stuff. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
