release note (known issue)

There is a known issue with the feature gate MaxUnavailableStatefulSet that is enabled by default as a beta feature in Kubernetes 1.35. This issue affects all SDP operators, especially the Trino operator.

To work around the issue there are two possibilities:

1. Disable this feature gate in your Kubenetes 1.35 clusters.
2. Ensure that your dev-ops pipelines create product custom resources (ex. TrinoCluster, SparkApplication, etc.) last, after any referenced custom resources such as TrinoCatalog, S3Connection and so on.
