There is no usage recommendations today and its value is questionable since we moved to CRDs that inter-operate mostly via conditions. Instead we plan to drop the dedicated semantic for terminal failure and keep improving Machine lifecycle signal through conditions. Therefore the Errors package [has been deprecated in v1.8](https://github.com/kubernetes-sigs/cluster-api/issues/10784). It's recommended to remove any usage of the currently exported variables. +- The `ClusterCacheTracker` component has been deprecated, please use the new `ClusterCache` instead. For more context and examples for + how to use it, see [PR: Introduce new ClusterCache](https://github.com/kubernetes-sigs/cluster-api/pull/11247) and the corresponding + [issue](https://github.com/kubernetes-sigs/cluster-api/issues/11272). Some notes: + - The `DisabledFor` option (previously `ClientUncachedObjects`) is not defaulted to `&corev1.ConfigMap` & `&corev1.Secret` anymore, + thus it's now necessary to explicitly set `DisabledFor` to avoid caching ConfigMaps and Secrets. + - `SecretClient` and `UserAgent` are now mandatory options, please take a look at the corresponding godoc.
