Description

Few examples of deprecation warnings with PHP 8.1

Deprecated: str_replace(): Passing null to parameter #2 ($replace) of type array|string is deprecated in /opt/app-root/src/vendor/cakephp/cakephp/src/Utility/Text.php on line 232

Deprecated (8192): Cake\Mailer\Email implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) [CORE/src/Mailer/Email.php, line 50]

Deprecated (8192): Return type of Cake\Chronos\Traits\FactoryTrait::createFromFormat($format, $time, $tz = null) should either be compatible with DateTime::createFromFormat(string $format, string $datetime, ?DateTimeZone $timezone = null): DateTime|false, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice [ROOT/vendor/cakephp/chronos/src/Traits/FactoryTrait.php, line 204]

Deprecated (8192): Return type of Cake\Chronos\Traits\FactoryTrait::getLastErrors() should either be compatible with DateTime::getLastErrors(): array|false, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice [ROOT/vendor/cakephp/chronos/src/Traits/FactoryTrait.php, line 327]

I am trying to follow the 4.X branch to see how much of that gets fixed.
