+We recommend using the latest version of typescript, however we currently ensure the driver's public types compile against `typescript@5.6.0`.
 This is the lowest typescript version guaranteed to work with our driver: older versions may or may not work - use at your own risk.
 Since typescript [does not restrict breaking changes to major versions](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes), we consider this support best effort.
 If you run into any unexpected compiler failures against our supported TypeScript versions, please let us know by filing an issue on our [JIRA](https://jira.mongodb.org/browse/NODE).
