Update Information:
**Version 6.5.0** (June 16th, 2021) * **SECURITY** Fixes **CVE-2021-34551**, a
complex RCE affecting Windows hosts. See SECURITY.md for details. * The fix for
this issue changes the way that language files are loaded. While they remain in
the same PHP-like format, they are processed as plain text, and any code in them
will not be run, including operations such as concatenation using the `.`
operator. * *Deprecation* The current translation file format using PHP arrays
is now deprecated; the next major version will introduce a new format. *
**SECURITY** Fixes **CVE-2021-3603** that may permit untrusted code to be run
from an address validator. See SECURITY.md for details. * The fix for this issue
includes a minor BC break: callables injected into `validateAddress`, or
indirectly through the `$validator` class property, may no longer be simple
strings. If you want to inject your own validator, provide a closure instead of
a function name. * Haraka message ID strings are now recognised
