Full Changelog: v7.0.0...v7.0.1

This is exactly the same as version 6.11.1 but bumps the major version number to indicate the presence of a BC break in child classes. The changes in 6.11.0 and 6.11.1 have been reverted in 6.12.0. If you have code that depends on those changes, please upgrade to 7.0.0 instead. Apologies for the mix up.

Specifically, lang(), setLanguage(), and $language are now static, and should be called statically.

This is a maintenance release that's exactly the same as 6.10.0, reverting everything that was released in 6.11.0 and 6.11.1 which inadvertently introduced a BC break affecting child classes. Apologies for the mix up.

PHPMailer 6.9.2

This is a maintenance release.

Changes

• Escape dots in SMTP transaction ID patterns
• Add link to aboutmy.email testing service in docs
• Add a more comprehensive example for using XOAUTH2 with gmail and Azure, thanks to @decomplexity

PHPMailer 6.9.1

This is a maintenance and feature release, adding support for the official release of PHP 8.3, methods for removing and replacing custom headers, XCLIENT support, and links to a new way of implementing XOAUTH2 authentication.

The only change likely to have any impact on existing code is that PHPMailer previously attempted to use opportunistic STARTTLS encryption when connecting to localhost, which was unlikely to work. The workaround required setting SMTPAutoTLS = false, but that's no longer required. You may still need to use this setting when connecting to literal IPs.

Changes

• Add support for official release of PHP 8.3, add experimental support for PHP 8.4
• Add clearCustomHeader and replaceCustomHeader methods
• Add support for the XCLIENT SMTP extension with setSMTPXclientAttribute and getSMTPXclientAttributes methods
• Don't attempt opportunistic TLS when connecting to localhost
• Add package link and example showing how to use @decomplexity's SendOauth2 wrapper
• Update example to show a better way of using an SMTP subclass
• Avoid some more deprecation warnings
• Update Danish and Polish translations
• Add Bengali and Assamese translations

Note: most of these changes were in the unreleased 6.9.0 version.
