 You can also create a custom image by building your own using the Packer scripts we provide. See [Build and Deploy Your Own Machine Image](#build-and-deploy-your-own-machine-image).
 
 ### How do I use a different license manager?
-The AMI uses MathWorks Hosted License Manager by default. For information on how to use other license managers, see [MATLAB Licensing in the Cloud](https://www.mathworks.com/help/licensingoncloud/matlab-on-the-cloud.html).

 #### **Customize MATLAB Release to Install**
-To use an earlier MATLAB release, you must use one of the variable definition files in the [release-config](https://github.com/mathworks-ref-arch/matlab-on-aws/tree/master/packer/v1/release-config) folder.
-These are available for MATLAB R2020a and later.
+To use an earlier MATLAB release, you must use one of the variable definition files in the [release-config](https://github.com/mathworks-ref-arch/matlab-on-aws/tree/master/packer/v1/release-config) folder. Note that although the files are available for MATLAB R2020a and later, MathWorks recommends using MATLAB R2023a or later. This is because the Packer builds for earlier releases use Ubuntu 20.04, which is no longer receiving security updates. 
 
 For example, install MATLAB R2020a and all available toolboxes.
