 We aim to support all Active LTS [Node.js releases](https://nodejs.org/en/about/previous-releases). We intend to support all Maintenance LTS versions until their official end-of-life. Removal of support for a Node.js version will be considered a breaking change and result in a major version bump of the SDK.
