 **NOTE:** If you've implemented your own classes that implement these interfaces from scratch, you will need to
 update your implementations to include the new methods or method changes to ensure compatibility.
 
-- **Cache:** ``CodeIgniter\Cache\CacheInterface::remember()`` now accepts a TTL callable. All built-in cache handlers inherit this method via ``BaseHandler``, so no changes are required for them.
+- **Cache:** ``CodeIgniter\Cache\CacheInterface::remember()`` now accepts a TTL callable. Custom implementations of ``CacheInterface`` must update the ``$ttl`` parameter type from ``int`` to `callable|int``.
 - **Database:** ``CodeIgniter\Database\ConnectionInterface`` now requires the ``afterCommit()``, ``afterRollback()``, ``inTransaction()``, and ``transaction()`` methods.
 - **Logging:** ``CodeIgniter\Log\Handlers\HandlerInterface::handle()`` now requires a third parameter ``array $context = []``. Any custom log handler that overrides ``handle()`` - whether implementing ``HandlerInterface`` directly or extending a built-in handler class - must add the parameter to its ``handle()`` method signature.
 - **Security:** The ``SecurityInterface``'s ``verify()`` method now has a native return type of ``static``.
