Check if affected (4)

breakingCrossplane CLI publication location and binary name
Applies if you use the Crossplane CLI.
The Crossplane CLI is no longer published to releases.crossplane.io. New releases are published only to cli.crossplane.io, with the binary name crossplane instead of crank.
breakingspec.replicas behavior in DeploymentRuntimeConfig
Applies if DeploymentRuntimeConfig configures spec.replicas.
Scaling to zero takes precedence over an explicit spec.replicas in a DeploymentRuntimeConfig. The field now specifies how many replicas to run while the runtime is active rather than requiring it to remain running.
breakingNarrowed composed resource garbage collection
Applicability is not stated in the release notes.
The composed resource garbage collector now deletes only resources whose controller reference points back to the XR.
