Incompatible Changes in EMQX 5.10

5.10.1

#15752 Listener connection rate limits (max_conn_rate and max_conn_burst) are now enforced per listener rather than per acceptor, restoring the pre-5.9.0 behavior. As a result, configurations from versions 5.9.0, 5.9.1, and 5.10.0 are incompatible: specified rates must be scaled up by the number of acceptors configured for respective listeners.

#15289 Added a new resource_opts.health_check_timeout configuration to all Connectors, Actions, and Sources, with a default value of 60 seconds. If a health check takes more than this to return a response, the Connector/Action/Source will be deemed disconnected.
Note: since the default is 60 seconds, this means that if a Connector/Action/Source previously could take more than that to return a healthy response, now it'll be deemed disconnected in such situations.
#15286 Configuration option broker.routing.storage_schema is now deprecated and ignored. Legacy v1 routing storage schema is no longer supported, and EMQX will refuse to start in a cluster running older versions that still use it. For instructions on upgrading a cluster that uses v1 routing schema, see Rolling Upgrade Considerations for EMQX 5.10 or Later.
#15239 The type for the multi_tenancy.default_max_sessions is now either infinity or a positive integer. Previously, 0 would be accepted.
#15156 Schema validation was added to dashboard.sso.oidc.issuer field. Now, this value is checked to be a valid URL.
