This is a maintenance release with a couple of bug fixes, coding standard changes, and a major overhaul to the testing system.

• CI builds now apply syntax & code style checks, so make your PRs tidy!

• Rename test scripts to PSR-4 spec

• Add SMTP transaction IDs to callbacks & allow for future expansion
• Expand test coverage

PHPMailer 6.0.0

Finally, after a couple of years work, PHPMailer 6.0 has been released!

This is a major update that breaks backwards compatibility. For information about what's changed, refer to the changelog and README files.

The most important changes are that PHPMailer now defines a namespace (PHPMailer\PHPMailer), and requires a minimum of PHP 5.5. To find out more about how to upgrade, read the upgrade guide.

PHPMailer 5.2.25

• Make obtaining SMTP transaction ID more reliable
• Add Bosnian translation

This is the last official release in the legacy PHPMailer 5.2 series; there may be future security patches (which will be found in the 5.2-stable branch), but no further non-security PRs or issues will be accepted. Migrate to PHPMailer 6.0.
