This major version upgrade from v7 to v9 of Nodemailer includes a significant breaking change in error handling and numerous security fixes.

Breaking Changes:

• v8.0.0: The error code 'NoAuth' has been renamed to 'ENOAUTH'. Any application logic that specifically checks for the 'NoAuth' error code must be updated to use 'ENOAUTH' to handle authentication failures correctly.

Security Fixes:
Upgrading from version 7.0.9 resolves multiple security vulnerabilities, including potential CRLF injections and improper certificate validation during OAuth2 token retrieval, which are fixed in v8.x releases.

Note on v9.0.1:
While the upgrade includes v9.0.1, detailed release notes for the v9.0.0 major release were not immediately available. Major version updates often include additional breaking changes. Developers should test thoroughly and review the official documentation for any new changes introduced in v9.

Source: Nodemailer CHANGELOG

Recommendation:
Review any error handling logic in your application that catches authentication errors from Nodemailer and update the error code from 'NoAuth' to 'ENOAUTH'. Given the major version jump, a full regression test of email-sending functionality is strongly recommended.
