Important: #91070 - SMTP transport option 'transport_smtp_encrypt' changed to boolean
See forge#91070
Description
With https://forge.typo3.org/issues/90295 the allowed value for
$GLOBALS
has been
changed to a boolean value.
symfony/mailer does no longer allow to specify the STARTTLS
usage, as it will
be used by default (if the server provides the needed support).
Therefore, the SMTP encryption configuration setting
$GLOBALS
is
automatically updated by the install tool's silent configuration upgrade.
The configuration value (string)tls
is removed to reflect that symfony/mailer
expects (bool)false
for STARTTLS
. Other values like (string)ssl
are
converted too (bool)true
.
No migration is needed at all, as no deprecation is thrown.
