Changes in MySQL Operator for Kubernetes 8.0.30-2.0.5 (2022-07-26, General Availability)

• Functionality Added or Changed

• Bugs Fixed

Functionality Added or Changed

• Updated the following dependencies: Kopf from v1.33.0 to v1.35.4, and the Kubernetes client from v18.20.0 to v23.6.0. (WL #15047)

• Group replication now uses the MySQL protocol to establish connections instead of the internal XCom communication infrastructure. Newly created clusters use the MySQL Protocol via port 3306, whereas clusters created using a previous version will continue to use XCom on port 33061.

  This also changes the minimum supported MySQL Server version from v8.0.24 to v8.0.27. (WL #15225)

• Added cert-manager (a CNCF project) support. (WL #15231)

Bugs Fixed

• Backup cron jobs were not deleted when their associated InnoDB Cluster was deleted. (Bug #33788741)

• Removed the AUDIT_READ securityContext capability; a feature introduced in Linux Kernel 3.16 which is too new for some K8s installations, such as Enterprise Linux 7. (Bug #107322, Bug #34218300)

• Added mycnf support in the InnoDB Cluster helm chart.

  Thanks to Ales Verbic for the contribution. (Bug #107082, Bug #34095308)
