Hello Team,

Please follow the instructions below to opt-in for OS security update.

This maintenance will require you to upgrade the engine version / instance type. and you might want to test it against your application first before applying it on production. Please plan the maintenance because we need to finish this before Jan 10, 2022 (PostgreSQL) and before January 31, 2022 (MySQL)
