Release notes

Sourced from phpmailer/phpmailer's releases.

PHPMailer 6.1.6

This is a security release, with some other minor changes. For full details, refer to the advisory.

• SECURITY Fix insufficient output escaping bug in file attachment names. CVE-2020-13625. Reported by Elar Lang of Clarified Security.
• Correct Armenian ISO language code from am to hy, add mapping for fallback
• Use correct timeout property in debug output

PHPMailer 6.1.5

This is a maintenance release.

• Reject invalid custom headers that are empty or contain breaks
• Various fixes for DKIM issues, especially when using mail() transport
• Drop the l= length tag from DKIM signatures; it's a mild security risk
• Ensure CRLF is used explicitly when needed, rather than static::$LE
• Add a method for trimming header content consistently
• Some minor tweaks to resolve static analyser complaints
• Check that attachment files are readable both when adding and when sending
• Work around Outlook bug in mishandling MIME preamble
• Danish translation improvements

PHPMailer 6.1.4

The RFC2047 folding added in 6.1.0 was a little overenthusiastic; It will now only happen when header lines exceed 998 chars.

• Clean up hostname handling
• Avoid IDN error on older PHP versions, prep for PHP 8.0
• Don't force RFC2047 folding unnecessarily
• Enable tests on full release of PHP 7.4
