v0.0.26

📦 In this release, we have considerably shaped our CRD APIs to eventually converge to a v1beta1 version. We have introduced several new fields with brand new functionallity, each of them documented in the respective PRs linked below alongside the relevant API reference.

🏗️ We have significantly changed the MariaDB Galera architecture to improve its overall stability and robustness:

• Liveness and readiness probes are now delegated to the agent. This enables better Galera cluster recovery and flexibility to introduce new features.
• agent and init images are now part of the mariadb-operator glued CLI.
• Introduction of a Galera init Job to execute initialization tasks prior to provisioning the StatefulSet.

⚙️ The automated Galera cluster recovery is now more predictable, robust and configurable. The user may now specify a minClusterSize, either as an absolute number of replicas (2) or relative (50%), that will tell the operator when the cluster is considered unhealthy so it can perform the recovery process after a given period of time defined by clusterHealthyTimeout. Refer to the Galera documentation for further detail.

💾 Some more new features, now related to the storage: The operator is now able to resize the volumes used by MariaDB without affecting its availability, enabling smooth scaling of both MariaDB storage capacity and the volume of data stored by your applications. Furthermore, we've streamlined our storage API to make it ridiculously simple, take a look at the storage documentation.

🔗 To enable better integrations with cloud providers and other CNCF projects, we have introduced support for inheritMetadata and serviceAccountName fields in the Backup, Restore and SqlJob resources. This allows you to use dedicated metadata (i.e. labels and annotations) and ServiceAccounts across all our batch Job and CronJob resources.

🛠️ To accomplish this, we've introduced some BREAKING CHANGES, please take a look at the upgrade guide. We've provided a migration script to facilitate the transition:
