This describes (roughly) the steps Strimzi users will need to take to get to using v1beta2 Strimzi APIs which in turn are using the v1 CRD API (Kubernetes 1.21 is expected to have removed CRD v1beta1). In it we talk about Strimzi 0.21.0 and 0.22.0, but the changes described under those headings wouldn’t necessarily need to be delivered in exactly those versions. Rather the requirement is that what we’re calling Strimzi 0.22 is released around the time that Kubernetes 1.21 is.
This will be the last version of Strimzi which supports Kubernetes 1.11-1.15.
