Release notes

Sourced from phpmailer/phpmailer's releases.

PHPMailer 6.4.1

This is a security release.

• SECURITY Fixes CVE-2020-36326, a regression of CVE-2018-19296 object injection introduced in 6.1.8, see SECURITY.md for details
• Reject more file paths that look like URLs, matching RFC3986 spec, blocking URLS using schemes such as ssh2
• Ensure method signature consistency in doCallback calls
• Ukrainian language update
• Add composer scripts for checking coding standards and running tests

Thanks to Fariskhi Vidyan for the report and assistance, and Tidelift for support.

PHPMailer 6.4.0

This is a maintenance release. The changes introduced in 6.3.0 for setting an envelope sender automatically when using mail() caused problems, especially in WordPress, so this change has been reverted. It gets a minor version bump as it's a change in behaviour, but only back to what 6.2.0 did. See #2298 for more info.

Other changes:

• Check for the mbstring extension before decoding addresss in parseAddress, so it won't fail if you don't have it installed
• Add Serbian Latin translation (sr_latn)
• Enrol PHPMailer in Tidelift, because supporting open-source is important!
