 ## Building
 
-You need either [Docker](https://github.com/docker/docker "Link to website of Docker") and `make` (Method 1), or [Go](https://go.dev/ "Link to website of Go") (Method 2) in order to build Traefik.
-For changes to its dependencies, the `dep` dependency management tool is required.
-
-### Method 1: Using `Docker` and `Makefile`
-
-Run make with the `binary` target.
-
-```bash
-make binary
-```
-
-This will create binaries for the Linux platform in the `dist` folder.
-
-In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define `DOCKER_NON_INTERACTIVE=true` environment variable.

+# SPIFFE
+
+Secure the backend connection with SPIFFE.
+{: .subtitle }
+
+[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
+provides a secure identity in the form of a specially crafted X.509 certificate, 
+to every workload in an environment.
+
+Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
+
+## Configuration
+
+### General
+
+Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
+It can be defined by using a file (YAML or TOML) or CLI arguments.
+
+### Workload API
+
+The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
+
+!!! info "Enabling SPIFFE in ServersTransports"
+
+    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
+    Each [ServersTransport](../routing/services/index.md#serverstransport_1) or [TCPServersTransport](../routing/services/index.md#serverstransport_2),
+	that is meant to be secured with SPIFFE,
+	must explicitly enable it (see [SPIFFE with ServersTransport](../routing/services/index.md#spiffe) or [SPIFFE with TCPServersTransport](../routing/services/index.md#spiffe_1)).
+
+!!! warning "SPIFFE can cause Traefik to stall"
+	When using SPIFFE,
+	Traefik will wait for the first SVID to be delivered before starting.
+	If Traefik is hanging when waiting on SPIFFE SVID delivery,
+	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

+
+# Tailscale
+
+Provision TLS certificates for your internal Tailscale services.
+{: .subtitle }
+
+To protect a service with TLS, a certificate from a public Certificate Authority is needed.
+In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
+
+## Certificate resolvers
+
+To obtain a TLS certificate from the Tailscale daemon,
+a Tailscale certificate resolver needs to be configured as below.
+
+!!! info "Referencing a certificate resolver"
+
+    Defining a certificate resolver does not imply that routers are going to use it automatically.
+    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.
+
+```yaml tab="File (YAML)"
+certificatesResolvers:
+    myresolver:
+        tailscale: {}
+```
+
+```toml tab="File (TOML)"
+[certificatesResolvers.myresolver.tailscale]
+```
+
+```bash tab="CLI"
+--certificatesresolvers.myresolver.tailscale=true
+```
+
+## Domain Definition
+
+A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
+
+- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
+  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
+
+- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
+  in the [router's rule](../routing/routers/index.md#rule).
+
+!!! info "Tailscale Domain Format"
+
+    The domain is only taken into account if it is a Tailscale-specific one,
+    i.e. of the form `machine-name.domains-alias.ts.net`.

 Handling Content-Type auto-detection

-The Content-Type middleware - or rather its `autoDetect` option -
-specifies whether to let the `Content-Type` header,
-if it has not been defined by the backend,
-be automatically set to a value derived from the contents of the response.
-
-As a proxy, the default behavior should be to leave the header alone,
-regardless of what the backend did with it.
-However, the historic default was to always auto-detect and set the header if it was not already defined,
-and altering this behavior would be a breaking change which would impact many users.
-
-This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
+The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
+when it is not set by the backend.
 
 !!! info
 
-    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
-    is still to automatically set the `Content-Type` header.
-    Therefore, given the default value of the `autoDetect` option (false),
-    simply enabling this middleware for a router switches the router's behavior.
-
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

+```
+
+## Configuration Options
+
+### `sourceRange`
+
+_Required_
+
+The `sourceRange` option sets the allowed IPs (or ranges of allowed IPs by using CIDR notation).
+
+### `ipStrategy`
+
+The `ipStrategy` option defines two parameters that set how Traefik determines the client IP: `depth`, and `excludedIPs`.  
+If no strategy is set, the default behavior is to match `sourceRange` against the Remote address found in the request.
+
+!!! important "As a middleware, whitelisting happens before the actual proxying to the backend takes place. In addition, the previous network hop only gets appended to `X-Forwarded-For` during the last stages of proxying, i.e. after it has already passed through whitelisting. Therefore, during whitelisting, as the previous network hop is not yet present in `X-Forwarded-For`, it cannot be matched against `sourceRange`."
+
+#### `ipStrategy.depth`
+
+The `depth` option tells Traefik to use the `X-Forwarded-For` header and take the IP located at the `depth` position (starting from the right).
+
+- If `depth` is greater than the total number of IPs in `X-Forwarded-For`, then the client IP will be empty.
+- `depth` is ignored if its value is less than or equal to 0.
+
+!!! example "Examples of Depth & X-Forwarded-For"
+
+    If `depth` is set to 2, and the request `X-Forwarded-For` header is `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` then the "real" client IP is `"10.0.0.1"` (at depth 4) but the IP used is `"12.0.0.1"` (`depth=2`).
+
+    | `X-Forwarded-For`                       | `depth` | clientIP     |
+    |-----------------------------------------|---------|--------------|
+    | `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` | `1`     | `"13.0.0.1"` |
+    | `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` | `3`     | `"11.0.0.1"` |
+    | `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` | `5`     | `""`         |

+# Configuration Details for Migrating from Traefik v2 to v3
+
+## Static Configuration Changes
+
+### SwarmMode
+
+In v3, the provider Docker has been split into 2 providers:
+
+- Docker provider (without Swarm support)
+- Swarm provider  (Swarm support only)
+
+??? example "An example usage of v2 Docker provider with Swarm"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        swarmMode: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker]
+        swarmMode=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.swarmMode=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+In v3, the `swarmMode` should not be used with the Docker provider, and, to use Swarm, the Swarm provider should be used instead.
+
+??? example "An example usage of the Swarm provider"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      swarm:
+        endpoint: "tcp://127.0.0.1:2377"
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.swarm]
+        endpoint="tcp://127.0.0.1:2377"
+    ```
+
+    ```bash tab="CLI"
+    --providers.swarm.endpoint=tcp://127.0.0.1:2377
+    ```
+
+#### TLS.CAOptional
+
+Docker provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the Docker provider static configuration.
+
+### Kubernetes Gateway API
+
+#### Experimental Channel Resources (TLSRoute and TCPRoute)
+
+In v3, the Kubernetes Gateway API provider does not enable support for the experimental channel API resources by default.
+
+##### Remediation
+
+The `experimentalChannel` option should be used to enable the support for the experimental channel API resources.
+
+??? example "An example usage of the Kubernetes Gateway API provider with experimental channel support enabled"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      kubernetesGateway:
+        experimentalChannel: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.kubernetesGateway]
+        experimentalChannel = true
+      # ...
+    ```
+
+    ```bash tab="CLI"
+    --providers.kubernetesgateway.experimentalchannel=true
+    ```
+
+### Experimental Configuration
+
+#### HTTP3
+
+In v3, HTTP/3 is no longer an experimental feature.
+It can be enabled on entry points without the associated `experimental.http3` option, which is now removed.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Experimental `http3` option"
+
+    ```yaml tab="File (YAML)"
+    experimental:
+      http3: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [experimental]
+        http3=true
+    ```
+
+    ```bash tab="CLI"
+    --experimental.http3=true
+    ```
+
+##### Remediation
+
+The `http3` option should be removed from the static configuration experimental section.
+To configure `http3`, please checkout the [entrypoint configuration documentation](../routing/entrypoints.md#http3_1).
+
+### Consul provider
+
+#### namespace
+
+The Consul provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Consul `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of Consul `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespaces=foobar
+    ```
+
+#### TLS.CAOptional
+
+Consul provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      consul:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.consul.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.consul.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the Consul provider static configuration.
+
+### ConsulCatalog provider
+
+#### namespace
+
+The ConsulCatalog provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 ConsulCatalog `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    consulCatalog:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consulCatalog]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --consulCatalog.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of ConsulCatalog `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    consulCatalog:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consulCatalog]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --consulCatalog.namespaces=foobar
+    ```
+
+#### Endpoint.TLS.CAOptional
+
+ConsulCatalog provider `endpoint.tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the Endpoint.TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      consulCatalog:
+        endpoint:
+          tls: 
+            caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.consulCatalog.endpoint.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.consulCatalog.endpoint.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `endpoint.tls.caOptional` option should be removed from the ConsulCatalog provider static configuration.
+
+### Nomad provider
+
+#### namespace
+
+The Nomad provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Nomad `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    nomad:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [nomad]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --nomad.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of Nomad `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    nomad:
+      namespaces:
+        - foobar
+    ```
+

+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --nomad.namespaces=foobar
+    ```
+
+#### Endpoint.TLS.CAOptional
+
+Nomad provider `endpoint.tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).

+### Rancher v1 Provider
+
+In v3, the Rancher v1 provider has been removed because Rancher v1 is [no longer actively maintained](https://rancher.com/docs/os/v1.x/en/support/),
+and Rancher v2 is supported as a standard Kubernetes provider.
+
+??? example "An example of Traefik v2 Rancher v1 configuration"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      rancher: {}
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.rancher]
+    ```
+
+    ```bash tab="CLI"
+    --providers.rancher=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
+As such, Rancher 2.x users should utilize the [Kubernetes CRD provider](../providers/kubernetes-crd.md) directly.
+
+Also, all Rancher provider related configuration should be removed from the static configuration.
+
+### Marathon provider
+
+Marathon maintenance [ended on October 31, 2021](https://github.com/mesosphere/marathon/blob/master/README.md).
+In v3, the Marathon provider has been removed.
+
+??? example "An example of v2 Marathon provider configuration"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      marathon: {}
+    ```

+    [providers.marathon]
+    ```
+
+    ```bash tab="CLI"
+    --providers.marathon=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All Marathon provider related configuration should be removed from the static configuration.
+
+### HTTP Provider
+
+#### TLS.CAOptional
+
+HTTP provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"

+
+InfluxDB v1.x maintenance [ended in 2021](https://www.influxdata.com/blog/influxdb-oss-and-enterprise-roadmap-update-from-influxdays-emea/).
+In v3, the InfluxDB v1 metrics provider has been removed.
+
+??? example "An example of Traefik v2 InfluxDB v1 metrics configuration"

+    ```
+
+In v2, Pilot configuration was deprecated and ineffective,
+it is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All Pilot related configuration should be removed from the static configuration.
+
+## Operations Changes
+
+### Traefik RBAC Update
+
+In v3, the support of `TCPServersTransport` has been introduced.
+When using the KubernetesCRD provider, it is therefore necessary to update [RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) and [CRD](../reference/dynamic-configuration/kubernetes-crd.md) manifests.
+
+### Content-Type Auto-Detection
+
+In v3, the `Content-Type` header is not auto-detected anymore when it is not set by the backend.
+One should use the `ContentType` middleware to enable the `Content-Type` header value auto-detection.
+
+### Observability
+
+#### gRPC Metrics
+
+In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.
+
+#### Tracing
+
+In v3, the tracing feature has been revamped and is now powered exclusively by [OpenTelemetry](https://opentelemetry.io/ "Link to website of OTel") (OTel).
+!!! warning "Important"
+    Traefik v3 **no** longer supports direct output formats for specific vendors such as Instana, Jaeger, Zipkin, Haystack, Datadog, and Elastic.
+    Instead, it focuses on pure OpenTelemetry implementation, providing a unified and standardized approach for observability.
+
+Here are two possible transition strategies:
+
+1. OTLP Ingestion Endpoints:
+
+    Most vendors now offer OpenTelemetry Protocol (OTLP) ingestion endpoints.
+    You can seamlessly integrate Traefik v3 with these endpoints to continue leveraging tracing capabilities.
+
+2. Legacy Stack Compatibility:
+
+    For legacy stacks that cannot immediately upgrade to the latest vendor agents supporting OTLP ingestion,
+    using OpenTelemetry (OTel) collectors with appropriate exporters configuration is a viable solution.
+    This allows continued compatibility with the existing infrastructure.
+
+Please check the [OpenTelemetry Tracing provider documention](../observability/tracing/opentelemetry.md) for more information.
+
+#### Internal Resources Observability
+
+In v3, observability for internal routers or services (e.g.: `ping@internal`) is disabled by default.
+To enable it one should use the new `addInternals` option for AccessLogs, Metrics or Tracing.
+Please take a look at the observability documentation for more information:
+
+- [AccessLogs](../observability/access-logs.md#addinternals)
+- [Metrics](../observability/metrics/overview.md#addinternals)
+- [Tracing](../observability/tracing/overview.md#addinternals)
+
+## Dynamic Configuration Changes
+
+### Router Rule Matchers
+
+In v3, a new rule matchers syntax has been introduced for HTTP and TCP routers.
+The default rule matchers syntax is now the v3 one, but for backward compatibility this can be configured.
+The v2 rule matchers syntax is deprecated and its support will be removed in the next major version.
+For this reason, we encourage migrating to the new syntax.
+
+By default, the `defaultRuleSyntax` static option is automatically set to `v3`, meaning that the default rule is the new one.
+
+#### New V3 Syntax Notable Changes
+
+The `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
+
+`PathPrefix` no longer uses regular expressions to match path prefixes.
+
+`QueryRegexp` has been introduced to match query values using a regular expression.
+
+`HeaderRegexp`, `HostRegexp`, `PathRegexp`, `QueryRegexp`, and `HostSNIRegexp` matchers now uses the [Go regexp syntax](https://golang.org/pkg/regexp/syntax/).
+
+All matchers now take a single value (except `Header`, `HeaderRegexp`, `Query`, and `QueryRegexp` which take two)
+and should be explicitly combined using logical operators to mimic previous behavior.
+
+`Query` can take a single value to match is the query value that has no value (e.g. `/search?mobile`).
+
+`HostHeader` has been removed, use `Host` instead.
+
+#### Remediation
+
+##### Configure the Default Syntax In Static Configuration
+
+The default rule matchers syntax is the expected syntax for any router that is not self opt-out from this default value.
+It can be configured in the static configuration.
+
+??? example "An example configuration for the default rule matchers syntax"
+
+    ```yaml tab="File (YAML)"
+    # static configuration
+    core:
+      defaultRuleSyntax: v2
+    ```
+
+    ```toml tab="File (TOML)"
+    # static configuration
+    [core]
+        defaultRuleSyntax="v2"
+    ```
+
+    ```bash tab="CLI"
+    # static configuration
+    --core.defaultRuleSyntax=v2
+    ```
+
+##### Configure the Syntax Per Router
+
+The rule syntax can also be configured on a per-router basis.
+This allows to have heterogeneous router configurations and ease migration.
+
+??? example "An example router with syntax configuration"
+
+```yaml tab="Docker & Swarm"
+labels:
+  - "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.io/v1alpha1
+kind: IngressRoute
+metadata:
+  name: test.route
+  namespace: default
+
+spec:
+  routes:
+    - match: PathPrefix(`/foo`, `/bar`)
+      syntax: v2
+      kind: Rule
+```
+
+```yaml tab="Consul Catalog"
+- "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="File (YAML)"
+http:
+  routers:
+    test:
+      ruleSyntax: v2
+```
+
+```toml tab="File (TOML)"
+[http.routers]
+  [http.routers.test]
+    ruleSyntax = "v2"
+```
+
+### IPWhiteList
+
+In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
+
+### Deprecated Options Removal
+
+- The `tracing.datadog.globaltag` option has been removed.
+- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Consul Catalog, and Docker providers.
+- `sslRedirect`, `sslTemporaryRedirect`, `sslHost`, `sslForceHost` and `featurePolicy` options of the Headers middleware have been removed.
+- The `forceSlash` option of the StripPrefix middleware has been removed.
+- The `preferServerCipherSuites` option has been removed.
+
+### TCP LoadBalancer `terminationDelay` option
+
+The TCP LoadBalancer `terminationDelay` option has been removed.
+This option can now be configured directly on the `TCPServersTransport` level, please take a look at this [documentation](../routing/services/index.md#terminationdelay)
+
+### Kubernetes CRDs API Group `traefik.containo.us`
+
+In v3, the Kubernetes CRDs API Group `traefik.containo.us` has been removed. 
+Please use the API Group `traefik.io` instead.
+
+### Kubernetes Ingress API Group `networking.k8s.io/v1beta1`
+
+In v3, the Kubernetes Ingress API Group `networking.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122)) support has been removed.
+
+Please use the API Group `networking.k8s.io/v1` instead.
+
+### Traefik CRD API Version `apiextensions.k8s.io/v1beta1`
+
+In v3, the Traefik CRD API Version `apiextensions.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#customresourcedefinition-v122)) support has been removed.
+
+Please use the CRD definition with the API Version `apiextensions.k8s.io/v1` instead.

+
+# Migration Guide: From v2 to v3
+
+How to Migrate from Traefik v2 to Traefik v3.
+{: .subtitle }
+
+With Traefik v3, we are introducing a streamlined transition process from v2. Minimal breaking changes have been made to specific options in the [static configuration](./v2-to-v3-details.md#static-configuration-changes "Link to static configuration changes"), and we are ensuring backward compatibility with v2 syntax in the [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes"). This will offer a gradual path for adopting the v3 syntax, allowing users to progressively migrate their Kubernetes ingress resources, Docker labels, etc., to the new format.
+
+Here are the steps to progressively migrate from Traefik v2 to v3:
+
+1. [Prepare configurations and test v3](#step-1-prepare-configurations-and-test-v3)
+1. [Migrate production instances to Traefik v3](#step-2-migrate-production-instances-to-traefik-v3)
+1. [Progressively migrate dynamic configuration](#step-3-progressively-migrate-dynamic-configuration)
+
+## Step 1: Prepare Configurations and Test v3
+
+Check the changes in [static configurations](./v2-to-v3-details.md#static-configuration-changes "Link to static configuration changes") and [operations](./v2-to-v3-details.md#operations-changes "Link to operations changes") brought by Traefik v3.
+Modify your configurations accordingly.
+
+Then, add the following snippet to the static configuration:
+
+```yaml
+# static configuration
+core:
+  defaultRuleSyntax: v2
+```
+
+This snippet in the static configuration makes the [v2 format](../migration/v2-to-v3-details.md#configure-the-default-syntax-in-static-configuration "Link to configure default syntax in static config") the default rule matchers syntax.
+
+Start Traefik v3 with this new configuration to test it.
+
+If you don’t get any error logs while testing, you are good to go!
+Otherwise, follow the remaining migration options highlighted in the logs.
+
+Once your Traefik test instances are starting and routing to your applications, proceed to the next step.
+
+## Step 2: Migrate Production Instances to Traefik v3
+
+We strongly advise you to follow a progressive migration strategy ([Kubernetes rolling update mechanism](https://kubernetes.io/docs/tutorials/kubernetes-basics/update/update-intro/ "Link to the Kubernetes rolling update documentation"), for example) to migrate your production instances to v3.
+
+!!! Warning
+    Ensure you have a [real-time monitoring solution](https://traefik.io/blog/capture-traefik-metrics-for-apps-on-kubernetes-with-prometheus/ "Link to the blog on capturing Traefik metrics with Prometheus") for your ingress traffic to detect issues instantly.
+
+During the progressive migration, monitor your ingress traffic for any errors. Be prepared to rollback to a working state in case of any issues.
+
+If you encounter any issues, leverage debug and access logs provided by Traefik to understand what went wrong and how to fix it.
+
+Once every Traefik instance is updated, you will be on Traefik v3!
+
+## Step 3: Progressively Migrate Dynamic Configuration
+
+!!! info
+    This step can be done later in the process, as Traefik v3 is compatible with the v2 format for [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes").
+    Enable Traefik logs to get some help if any deprecated option is in use.
+
+Check the changes in [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes").
+
+Then, progressively [switch each router to the v3 syntax](./v2-to-v3-details.md#configure-the-syntax-per-router "Link to configuring the syntax per router").
+
+Test and update each Ingress resource and ensure that ingress traffic is not impacted.
+
+Once a v3 Ingress resource migration is validated, deploy the resource and delete the v2 Ingress resource.
+Repeat it until all Ingress resources are migrated.
+
+Now, remove the following snippet added to the static configuration in Step 1:
+
+```yaml
+# static configuration
+core:
+  defaultRuleSyntax: v2
+```
+
+You are now fully migrated to Traefik v3 🎉

 ### Traefik Hub
 
 In `v2.10`, Traefik Hub configuration has been removed because Traefik Hub v2 doesn't require this configuration.
+
+## v2.11
+
+### IPWhiteList (HTTP)
+
+In `v2.11`, the `IPWhiteList` middleware is deprecated, please use the [IPAllowList](../middlewares/http/ipallowlist.md) middleware instead.
+

+
+### TLS CipherSuites
+
+> By default, cipher suites without ECDHE support are no longer offered by either clients or servers during pre-TLS 1.3 handshakes.
+> This change can be reverted with the `tlsrsakex=1 GODEBUG` setting.
+> (https://go.dev/doc/go1.22#crypto/tls)
+
+The _RSA key exchange_ cipher suites are way less secure than the modern ECDHE cipher suites and exposes to potential vulnerabilities like [the Marvin Attack](https://people.redhat.com/~hkario/marvin).
+Decision has been made to support ECDHE cipher suites only by default.
+
+The following ciphers have been removed from the default list:
+
+- `TLS_RSA_WITH_AES_128_CBC_SHA`
+- `TLS_RSA_WITH_AES_256_CBC_SHA`
+- `TLS_RSA_WITH_AES_128_GCM_SHA256`
+- `TLS_RSA_WITH_AES_256_GCM_SHA384`
+
+To enable these ciphers, please set the option `CipherSuites` in your [TLS configuration](../https/tls.md#cipher-suites) or set the environment variable `GODEBUG=tlsrsakex=1`.
+
+### Minimum TLS Version
+
+> By default, the minimum version offered by `crypto/tls` servers is now TLS 1.2 if not specified with config.MinimumVersion,
+> matching the behavior of crypto/tls clients.
+> This change can be reverted with the `tls10server=1 GODEBUG` setting.
+> (https://go.dev/doc/go1.22#crypto/tls)
+
+To enable TLS 1.0, please set the option `MinVersion` to `VersionTLS10` in your [TLS configuration](../https/tls.md#cipher-suites) or set the environment variable `GODEBUG=tls10server=1`.
+
+## v2.11.1
+
+### Maximum Router Priority Value
+
+Before v2.11.1, the maximum user-defined router priority value is:
+
+- `MaxInt32` for 32-bit platforms,
+- `MaxInt64` for 64-bit platforms.
+
+Please check out the [go documentation](https://pkg.go.dev/math#pkg-constants) for more information.
+
+In v2.11.1, Traefik reserves a range of priorities for its internal routers and now, 
+the maximum user-defined router priority value is:
+
+- `(MaxInt32 - 1000)` for 32-bit platforms,
+- `(MaxInt64 - 1000)` for 64-bit platforms.
+
+### EntryPoint.Transport.RespondingTimeouts.<Timeout>
+
+Starting with `v2.11.1` the following timeout options are deprecated:
+
+- `<entryPoint>.transport.respondingTimeouts.readTimeout`
+- `<entryPoint>.transport.respondingTimeouts.writeTimeout`
+- `<entryPoint>.transport.respondingTimeouts.idleTimeout`
+
+They have been replaced by:
+
+- `<entryPoint>.transport.respondingTimeouts.http.readTimeout`
+- `<entryPoint>.transport.respondingTimeouts.http.writeTimeout`
+- `<entryPoint>.transport.respondingTimeouts.http.idleTimeout`
+
+### EntryPoint.Transport.RespondingTimeouts.TCP.LingeringTimeout
+
+Starting with `v2.11.1` a new `lingeringTimeout` entryPoints option has been introduced, with a default value of 2s.
+
+The lingering timeout defines the maximum duration between each TCP read operation on the connection.
+As a layer 4 timeout, it applies during HTTP handling but respects the configured HTTP server `readTimeout`.
+
+This change avoids Traefik instances with the default configuration hanging while waiting for bytes to be read on the connection.
+
+We suggest to adapt this value accordingly to your situation.
+The new default value is purposely narrowed and can close the connection too early.
+
+Increasing the `lingeringTimeout` value could be the solution notably if you are dealing with the following errors:
+
+- TCP: `Error while handling TCP connection: readfrom tcp X.X.X.X:X->X.X.X.X:X: read tcp X.X.X.X:X->X.X.X.X:X: i/o timeout`
+- HTTP: `'499 Client Closed Request' caused by: context canceled`
+- HTTP: `ReverseProxy read error during body copy: read tcp X.X.X.X:X->X.X.X.X:X: use of closed network connection`
+
+## v2.11.2
+
+### LingeringTimeout
+
+Starting with `v2.11.2` the `<entrypoint>.transport.respondingTimeouts.tcp.lingeringTimeout` introduced in `v2.11.1` has been removed.
+
+### RespondingTimeouts.TCP and RespondingTimeouts.HTTP
+
+Starting with `v2.11.2` the `respondingTimeouts.tcp` and `respondingTimeouts.http` sections introduced in `v2.11.1` have been removed.
+To configure the responding timeouts, please use the [`respondingTimeouts`](../routing/entrypoints.md#respondingtimeouts) section.  
+
+### EntryPoint.Transport.RespondingTimeouts.ReadTimeout
+
+Starting with `v2.11.2` the entryPoints [`readTimeout`](../routing/entrypoints.md#respondingtimeouts) option default value changed to 60 seconds.
+
+For HTTP, this option defines the maximum duration for reading the entire request, including the body.
+For TCP, this option defines the maximum duration for the first bytes to be read on the connection.
+
+The default value was previously set to zero, which means no timeout.
+
+This change has been done to avoid Traefik instances with the default configuration to be hanging forever while waiting for bytes to be read on the connection.
+
+Increasing the `readTimeout` value could be the solution notably if you are dealing with the following errors:
+
+- TCP: `Error while handling TCP connection: readfrom tcp X.X.X.X:X->X.X.X.X:X: read tcp X.X.X.X:X->X.X.X.X:X: i/o timeout`
+- HTTP: `'499 Client Closed Request' caused by: context canceled`

 ## Log Rotation
 
-Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
-This allows the logs to be rotated and processed by an external program, such as `logrotate`.
+The rotation of the log files can be configured with the following options.
 
-!!! warning
-    This does not work on Windows due to the lack of USR signals.
+### `maxSize`
+
+`maxSize` is the maximum size in megabytes of the log file before it gets rotated.
+It defaults to 100 megabytes.
+
+```yaml tab="File (YAML)"

 # Metrics
 
-Traefik supports these metrics backends:
+Traefik provides metrics in the [OpenTelemetry](./opentelemetry.md) format as well as the following vendor specific backends:
 
 - [Datadog](./datadog.md)
-- [InfluxDB](./influxdb.md)
 - [InfluxDB2](./influxdb2.md)
 - [Prometheus](./prometheus.md)
 - [StatsD](./statsd.md)
 
+Traefik Proxy hosts an official Grafana dashboard for both [on-premises](https://grafana.com/grafana/dashboards/17346)
+and [Kubernetes](https://grafana.com/grafana/dashboards/17347) deployments.
+
+## Common Options
+
+### `addInternals`
+
+_Optional, Default="false"_
+
+Enables metrics for internal resources (e.g.: `ping@internals`).
+
+```yaml tab="File (YAML)"

+# Overview
+
+Traefik's Observability system
+{: .subtitle }
+
+## Logs
+
+Traefik logs informs about everything that happens within Traefik (startup, configuration, events, shutdown, and so on).
+
+Read the [Logs documentation](./logs.md) to learn how to configure it.
+
+## Access Logs
+
+Access logs are a key part of observability in Traefik.
+
+They are providing valuable insights about incoming traffic, and allow to monitor it.
+The access logs record detailed information about each request received by Traefik,
+including the source IP address, requested URL, response status code, and more.
+
+Read the [Access Logs documentation](./access-logs.md) to learn how to configure it.
+
+## Metrics
+
+Traefik offers a metrics feature that provides valuable insights about the performance and usage.
+These metrics include the number of requests received, the requests duration, and more.
+
+On top of supporting metrics in the OpenTelemetry format, Traefik supports the following vendor specific metrics systems: Prometheus, Datadog, InfluxDB 2.X, and StatsD.
+
+Read the [Metrics documentation](./metrics/overview.md) to learn how to configure it.
+
+## Tracing
+
+The Traefik tracing system allows developers to gain deep visibility into the flow of requests through their infrastructure.
+
+Traefik provides tracing information in the OpenTelemery format.
+
+Read the [Tracing documentation](./tracing/overview.md) to learn how to configure it.
