flomesh-io/fsm v1.5.3 deprecates CRDs requiring pre-upgrade review

The flomesh-io/fsm project has released version 1.5.3, as noted in its GitHub release notes. This update includes several changes, among which are the deprecation of specific Custom Resource Definitions (CRDs). The affected CRDs are located in the following files: cmd/fsm-bootstrap/crds/config.flomesh.io_meshconfigs.yaml and cmd/fsm-bootstrap/crds/connector.flomesh.io_nacosconnectors.yaml. Operators are advised to review these changes carefully before upgrading.

When CRDs are deprecated, it often signals that their functionality may be removed or altered in future versions. Operators should check whether these CRDs are actively used in their current deployments and assess the impact of their deprecation on workflows, integrations, and automation. Additionally, any tooling or scripts that interact with these CRDs should be reviewed for compatibility. This aligns with a broader pattern in projects where CRD updates often precede significant architectural changes, making proactive preparation critical for smooth transitions.
