in `v2.8.2` the `preferServerCipherSuites` option is also deprecated and ignored in Traefik.
In `v2.8.2`, Traefik now reject certificates signed with the SHA-1 hash function. ([details](https://tip.golang.org/doc/go1.18#sha1))
## 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`.
