Worked on PHPMailer/PHPMailer to consolidate the deprecation policy for improved API lifecycle clarity and reduced user-facing warnings. Focused on backend development using PHP, the work enabled explicit disabling of the IMAP extension without triggering unnecessary deprecation warnings, while ensuring that enabling IMAP still surfaces relevant notices due to ext-imap deprecation. Deprecated the parseAddresses method and updated documentation to clarify supported API usage, simplifying migration paths for users and easing future maintenance for contributors. The approach emphasized clear documentation and maintainable code, addressing both technical and user experience aspects within the repository over the course of the month.
