v1.0.0

New Features

Some features of this release include:

• HA cluster remains writable during upgrade from 5.7 to 8.0
• Downtime during upgrade from 5.7 to 8.0 reduced when enabling galera-agent TLS. Previous alpha release experienced extended downtime during upgrade.

Breaking Changes

• Only ubuntu-jammy and ubuntu-bionic stemcells are supported. ubuntu-xenial is NOT supported.

• The mechanism for creating users has been updated. It is necessary to add the following to the deployment manifest for the pxc job

  jobs:
  - name: pxc-mysql
   properties:
     seeded_users:
       cluster-health-logger:
         host: localhost
         password: ((cf_mysql_mysql_cluster_health_password))
         role: minimal
       galera-agent:
         host: localhost
         password: ((cf_mysql_mysql_galera_healthcheck_db_password))
         role: minimal
       smoke-tests-user:
         host: any
         password: ((smoke_tests_db_password))
         role: schema-admin
         schema: pxc_release_test_db
  

  This requirement will be lifted in a future patch release.
