CiviCRM 5.53 update notice refers to required Message Template changes and links to "Variables and tokens in Workflow message templates" but that section does not tell users what actually needs to be updated in the Message Templates. Referring to this page, https://docs.civicrm.org/user/en/latest/email/message-templates/#variables-and-tokens-in-workflow-message-templates
My reading of that page is that tokens are now available but the existing smarty variables have not changed. Therefore no change to the customised Message Templates is required at all, which is different to the CiviCRM upgrade notice for this release. This information should not be part of the CiviCRM upgrade notice unless some action is required as part of the upgrade.
The update instructions should go here, https://docs.civicrm.org/sysadmin/en/latest/upgrade/version-specific/
