Please see the changelog for a full list of changes, and the release blog for more information.
Please familiarise yourself with those changes before updating from an earlier release:
- The object cast operator was removed in favour of the class statement introduced in version 4.2.
- The global $connection and $transaction variables in the SMTP server's script contexts have been reserved for future use, and cannot be used.
- If using the ScanDLP() function's RULE pattern syntax with regular expressions, you need to manually add desired modifiers.
The following deprecation warnings will appear in preparation for future changes:
- The variables $tlsprotocol, $tlscipher and $tlskeysize in the RCPT script will be removed, and the script validation does no longer recognise those. This makes it impossible to save a script using those. The GetTLS() function should be used instead.
