 in `v2.8.2` the `preferServerCipherSuites` option is also deprecated and ignored in Traefik.

+## v2.8.3

+Since `v2.8.2`, when using the [file provider](https://doc.traefik.io/traefik/v2.8/providers/file/),
+malformed options of the [dynamic configuration](https://doc.traefik.io/traefik/v2.8/getting-started/configuration-overview/#the-dynamic-configuration) are detected.
+If a string is used as a value for a list/array in a configuration file an error is raised.
+
+In `v2.8.2`, the malformed dynamic configuration produced a panic, which is now reported as an error in `v2.8.3`.
+
+If you are using the [file provider](https://doc.traefik.io/traefik/v2.8/providers/file/) to define the dynamic configuration,
+we recommend using a [JSON Schema](https://www.schemastore.org/json/) to validate the configuration before upgrading to a version higher than `v2.8.1`.
