Amazon RDS for MySQL supports new minor version 8.0.26, includes Global Transaction Identifiers (GITDs) and Delayed Replication

Following the release of updates in MySQL version 8.0, we have updated Amazon Relational Database Service (Amazon RDS) for MySQL and Amazon RDS for MySQL on Outposts to support MySQL minor version 8.0.26. We recommend that you upgrade to the latest minor version to fix known security vulnerabilities in prior versions of MySQL, and to benefit from the numerous bug fixes, performance improvements, and new functionality added by the MySQL community.
