+### MySQL now defaults to `utf8mb4` {#mysql-utf8mb4}
+
+MySQL will now use `utf8mb4` by default rather than plain `utf8`. This provides better support for emojis and other special characters.
+
+Depending on when you created your Silverstripe CMS project, you may already be using `utf8mb4` as the default encoding. The `silverstripe/installer` has included a configuration file setting your database settings to `utf8mb4` for a few years.
+
+When upgrading your Silverstripe CMS project, review the `app/_config/mysite.yml` file and remove the following lines if they exist:
+
+```yml
+# UTF8MB4 has limited support in older MySQL versions.
+# Remove this configuration if you experience issues.
+---
+Name: myproject-database

+SilverStripe\ORM\Connect\MySQLDatabase:
+  connection_charset: utf8mb4
+  connection_collation: utf8mb4_unicode_ci
+  charset: utf8mb4
+  collation: utf8mb4_unicode_ci

 ### `DBDecimal` default value {#dbdecimal-default-value}
 
 Previously if an invalid default value was provided for a [`DBDecimal`](api:SilverStripe\ORM\FieldType\DBDecimal) database column, it would silently set the defalt value to `0`. This will now throw an exception instead, so that you're aware your configured value is invalid and can correct it.

+### `RedirectorPage` validation
 
 [`RedirectorPage`](api:SilverStripe\CMS\Model\RedirectorPage) now uses the [`Url` constraint](https://symfony.com/doc/current/reference/constraints/Url.html) from `symfony/validator` to validate the `ExternalURL` field. It will no longer add `http://` to the start of URLs for you if you're missing a protocol - instead, a validation error message will be displayed.
