Associated Helm release is v0.46.1: https://github.com/fluent/helm-charts/blob/fluent-bit-0.46.1/charts/fluent-bit/Chart.yaml#L8-L9

Approach

Fluent don't publish specifics regarding Kubernetes version compatibility. Release / upgrades notes make no mention of breaking changes. However this is a major release with new functionality added, so thorough checking of changelogs and testing is important.

• review release notes & changelogs
• test bumping helm charts / image refs for logging and modsec ingress fluentbit instances
• switch fluentbit output from kibana ship to stdout and tail logs (in test clusters)
• check integration tests (live-2)
