Starting today, long-term support (LTS) will be provided on Amazon Aurora MySQL-Compatible Edition 3 (with MySQL 8.0 compatibility) on the Aurora MySQL 3.04 (compatible with MySQL 8.0.28) minor version. Database clusters that use LTS releases can stay on the same minor version for at least three years. During the lifetime of an Aurora MySQL LTS release, new patches introduce fixes to critical matters such as security issues. These patches don’t include any new features.
