Release 0.6.0 of the MySQL operator comes with a series of breaking changes in order to support the replacement of the old Helm 2 charts. There are parameters that have been split, renamed, have a different default value or have been completely dropped. By doing so, now the parameter naming is following the Kubernetes standard for naming labels, which you may find here: Kubernetes common labels. If you’re not using this already in your projects, you might do so in order to avoid later edits of parameters, which are a source of errors and issues.
Here is the detailed list of the breaking changes related to the configuration parameters for the MySQL operator chart.

If you are using the MySQL operator, updating to the new release should be done with care, by reviewing first the parameters that you are using in your configuration. Upgrading the operator can be done by removing the version that you are using and installing 0.6.0. The documentation reference for upgrading to 0.6.0 is available over here.
Here at Bitpoke we are looking forward to hear about the MySQL Operator use cases, stories and ideas here or at hello@bitpoke.io to improve the project.
