This major version upgrade from v3 to v4 introduces breaking changes, most notably in the naming of API parameters.

Key Breaking Change:

• Parameter Renaming: The reply_to parameter has been renamed to replyTo. Code using the old reply_to parameter will need to be updated to use the new camelCase replyTo parameter to ensure functionality.

This change requires direct code modification to maintain correct behavior. Given the lack of a formal changelog for the v4.0.0 release, there may be other undocumented changes.

Source: GitHub Issue discussing the replyTo change

Recommendation:
Developers should perform a global search for reply_to in their calls to the Resend SDK and replace it with replyTo. Due to the uncertainty around other potential breaking changes, thorough testing of all email-sending functionality is strongly recommended after this upgrade.
