 > - The `ck8s init` command now requires a cluster argument which can be either of `<wc|sc|both>`.
 > - Alerts for low remaining free space has changed. There is no longer a **critical** level alert for when free disk space is predicted to run out, but a `warning` level alert remains. Other disk low free disk space alerts have been tweaked.
 > - The default config for storage class name on upcloud has changed from `upcloud-block-storage` to `standard`. This will impact prometheus and log-manager PVCs if they are enabled.
+> - [Upstream incubating and sandbox falco rules are now disabled by default](https://github.com/elastisys/compliantkubernetes-apps/blob/v0.34.0/config/config/common-config.yaml#L111-L119), custom rules overriding these must either be removed or the upstream rules re-enabled, else the falco pods will crash.
