+## v2.4 to v2.5
+
+### Kubernetes CRD
+
+In `v2.5`, the [Traefik CRDs](../reference/dynamic-configuration/kubernetes-crd.md#definitions) have been updated to support the new API version `apiextensions.k8s.io/v1`.
+As required by `apiextensions.k8s.io/v1`, we have included the OpenAPI validation schema.
+
+After deploying the new [Traefik CRDs](../reference/dynamic-configuration/kubernetes-crd.md#definitions), the resources will be validated only on creation or update.
+
+Please note that the unknown fields will not be pruned when migrating from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1` CRDs.
+For more details check out the official [documentation](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#specifying-a-structural-schema).
+
+### Kubernetes Ingress
+
+Traefik v2.5 moves forward for the Ingress provider to support Kubernetes v1.22.
+
+Traefik now supports only v1.14+ Kubernetes clusters, which means the support of `extensions/v1beta1` API Version ingresses has been dropped.
+
+The `extensions/v1beta1` API Version should now be replaced either by `networking.k8s.io/v1beta1` or by `networking.k8s.io/v1` (as of Kubernetes v1.19+).
+
+The support of the `networking.k8s.io/v1beta1` API Version will stop in Kubernetes v1.22.
+
+### Headers middleware: ssl redirect options
+
+`sslRedirect`, `sslTemporaryRedirect`, `sslHost` and `sslForceHost` are deprecated in Traefik v2.5.
+
+For simple HTTP to HTTPS redirection, you may use [EntryPoints redirections](../routing/entrypoints.md#redirection).
+
+For more advanced use cases, you can use either the [RedirectScheme middleware](../middlewares/http/redirectscheme.md) or the [RedirectRegex middleware](../middlewares/http/redirectregex.md).
+
+### Headers middleware: accessControlAllowOrigin
+
+`accessControlAllowOrigin` is no longer supported in Traefik v2.5.
+
+### X.509 CommonName Deprecation Bis
+
+Following up on the deprecation started [previously](#x509-commonname-deprecation),
+as the `x509ignoreCN=0` value for the `GODEBUG` is [deprecated in Go 1.17](https://tip.golang.org/doc/go1.17#crypto/x509),
+the legacy behavior related to the CommonName field can not be enabled at all anymore.
+
+## v2.5.3 to v2.5.4
+
+### Errors middleware
+
+In `v2.5.4`, when the errors service is configured with the [`PassHostHeader`](../routing/services/index.md#pass-host-header) option to `true` (default),
+the forwarded Host header value is now set to the client request Host value and not `0.0.0.0`.
+Check out the [Errors middleware](../middlewares/http/errorpages.md#service) documentation for more details.
+
+## v2.5 to v2.6
+
+### HTTP3
+
+Traefik v2.6 introduces the `AdvertisedPort` option,
+which allows advertising, in the `Alt-Svc` header, a UDP port different from the one on which Traefik is actually listening (the EntryPoint's port).
+By doing so, it introduces a new configuration structure `http3`, which replaces the `enableHTTP3` option (which therefore doesn't exist anymore).
+To enable HTTP3 on an EntryPoint, please check out the [HTTP3 configuration](../routing/entrypoints.md#http3) documentation.
+
+### Kubernetes Gateway API Provider
+
+In `v2.6`, the [Kubernetes Gateway API provider](../providers/kubernetes-gateway.md) now only supports the version [v1alpha2](https://gateway-api.sigs.k8s.io/v1alpha2/guides/getting-started/) of the specification and 
+[route namespaces](https://gateway-api.sigs.k8s.io/v1alpha2/references/spec/#gateway.networking.k8s.io/v1alpha2.RouteNamespaces) selectors, which requires Traefik to fetch and watch the cluster namespaces.
+Therefore, the [RBAC](../reference/dynamic-configuration/kubernetes-gateway.md#rbac) and [CRD](../reference/dynamic-configuration/kubernetes-gateway.md#definitions) definitions must be updated.

+                  belonging to different Gateways. \n For example, an implementation

+                  within the group specifies either    the \"HTTPS\" or \"TLS\" Protocol.
+                  \n 2. Each Listener within the group specifies a Hostname that is
+                  unique    within the group. \n 3. As a special case, one Listener
+                  within a group may omit Hostname,    in which case this Listener

+                  That is, exact matches must be processed before wildcard matches.
+                  \n If this field specifies multiple Listeners that have the same
