+On March 26, 2024, Segment upgraded the Functions runtime environment to Node.js v18, which is the current long-term support (LTS) release.
 
 This upgrade keeps your runtime current with industry standards. Based on the [AWS Lambda](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html){:target="_blank"} and [Node.js](https://nodejs.org/en/about/previous-releases){:target="_blank"} support schedule, Node.js v16 is no longer in *Maintenance LTS*. Production applications should only use releases of Node.js that are in *Active LTS* or *Maintenance LTS*.
 
-All new functions will use Node.js v18 starting March 26, 2024.
+For existing functions, this change automatically occurs as you update and deploy an existing function. Segment recommends that you check your function post-deployment to ensure everything's working. Your function may face issues due to the change in syntax between different Node.js versions and dependency compatibility.

 Settings allow you to pass configurable variables to your function, which is the best way to pass sensitive information such as security tokens.
