 ## Impact
 
+### Pilot
+
+Metrics will continue to function normally up to 2.8, when they will be disabled.  
+In 2.9, the Pilot platform and all Traefik integration code will be permanently removed.
+
+Starting on 2.7 the pilot token will not be a requirement anymore for plugins.  
+Since 2.8, a [new plugin catalog](https://plugins.traefik.io) is available, decoupled from Pilot.
+
+### Consul Enterprise Namespace
+
+Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated, 
+please use the `namespaces` options instead.  
+
+### TLS 1.0 and 1.1
+
+Starting on 2.8 the default TLS options will use the minimum version of TLS 1.2. Of course, it can still be overridden with custom configuration.  
+
+### Nomad Namespace
+
+Starting on 2.10 the `namespace` option of the Nomad provider is deprecated,
+please use the `namespaces` options instead.
+
+### Kubernetes CRD Provider API Group `traefik.containo.us`
+
+In v2.10, the Kubernetes CRD provider API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.
+
 ### Kubernetes CRD Provider API Version `traefik.io/v1alpha1`
 
-The Kubernetes CRD provider API Version `traefik.io/v1alpha1` is deprecated in Traefik v3.
-Please use the API Group `traefik.io/v1` instead.
-
-### Kubernetes Ingress API Version `networking.k8s.io/v1beta1`
-
-The Kubernetes Ingress API Version `networking.k8s.io/v1beta1` support is removed in v3. 
-Please use the API Group `networking.k8s.io/v1` instead.

-### Exposing the Traefik dashboard
-
-This Helm chart does not expose the Traefik dashboard by default, for security concerns.
-Thus, there are multiple ways to expose the dashboard.
-For instance, the dashboard access could be achieved through a port-forward:
-
-```shell
-kubectl port-forward $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000
-```
-
-It can then be reached at: `http://127.0.0.1:9000/dashboard/`
-
-Another way would be to apply your own configuration, for instance,
-by defining and applying an IngressRoute CRD (`kubectl apply -f dashboard.yaml`):
-
-```yaml
-# dashboard.yaml
-apiVersion: traefik.io/v1alpha1

-# 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.

-```bash tab="CLI"

-
-## 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`.

+Traefik is an [open-source](https://github.com/traefik/traefik) *Application Proxy* that makes publishing your services a fun and easy experience. 
+It receives requests on behalf of your system and identifies which components are responsible for handling them, and routes them securely. 
 
 What sets Traefik apart, besides its many features, is that it automatically discovers the right configuration for your services. 
 The magic happens when Traefik inspects your infrastructure, where it finds relevant information and discovers which service serves which request. 
 
-Traefik is natively compliant with every major cluster technology, such as Kubernetes, Docker, Docker Swarm, AWS, and [the list goes on](providers/overview.md); and can handle many at the same time. (It even works for legacy software running on bare metal.)

 With Traefik, there is no need to maintain and synchronize a separate configuration file: everything happens automatically, in real time (no restarts, no connection interruptions).
-With Traefik, you spend time developing and deploying new features to your system, not on configuring and maintaining its working state.   
+With Traefik, you spend time developing and deploying new features to your system, not on configuring and maintaining its working state.

 Handling Content-Type auto-detection
 {: .subtitle }
 
-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.
+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.
 
 !!! 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).

-The Retry middleware reissues requests a given number of times to a backend server if that server does not reply.
-As soon as the server answers, the middleware stops retrying, regardless of the response status.
+The Retry middleware reissues requests a given number of times when it cannot contact the backend service. 
+This applies at the transport level (TCP). 
+If the service does not respond to the initial connection attempt, the middleware retries.
+However, once the service responds, regardless of the HTTP status code, the middleware considers it operational and stops retrying.
+This means that the retry mechanism does not handle HTTP errors; it only retries when there is no response at the TCP level.
 The Retry middleware has an optional configuration to enable an exponential backoff.

-description: "Migrate from Traefik Proxy v2 to v3 and update all the necessary configurations to take advantage of all the improvements. Read the technical documentation."
----
-
-# Migration Guide: From v2 to v3
-
-How to Migrate from Traefik v2 to Traefik v3.
-{: .subtitle }
-
-The version 3 of Traefik introduces a number of breaking changes,
-which require one to update their configuration when they migrate from v2 to v3.
-The goal of this page is to recapitulate all of these changes,
-and in particular to give examples, feature by feature, 
-of how the configuration looked like in v2,
-and how it now looks like in v3.
-
-## Static configuration
-
-### Docker & Docker Swarm
-
-#### 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.
-
-### 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.
-
-### 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).

-##### 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"

-        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"

-        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

-
-??? example "An example usage of Nomad `namespaces` option"
-
-    ```yaml tab="File (YAML)"
-    nomad:
-      namespaces:
-        - foobar
-    ```
-
-    ```toml tab="File (TOML)"
-    [nomad]
-        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).
-
-??? example "An example usage of the Endpoint.TLS.CAOptional option"
-
-    ```yaml tab="File (YAML)"
-    providers:
-      nomad:
-        endpoint:
-          tls: 
-            caOptional: true
-    ```
-
-    ```toml tab="File (TOML)"
-    [providers.nomad.endpoint.tls]
-        caOptional=true
-    ```
-
-    ```bash tab="CLI"
-    --providers.nomad.endpoint.tls.caOptional=true
-    ```
-
-##### Remediation
-
-The `endpoint.tls.caOptional` option should be removed from the Nomad provider static configuration.
-
-### 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: {}
-    ```
-
-    ```toml tab="File (TOML)"
-    [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)"
-    providers:
-      http:
-        tls: 
-          caOptional: true
-    ```
-
-    ```toml tab="File (TOML)"
-    [providers.http.tls]
-        caOptional=true
-    ```
-
-    ```bash tab="CLI"
-    --providers.http.tls.caOptional=true
-    ```
-
-##### Remediation
-
-The `tls.caOptional` option should be removed from the HTTP provider static configuration.

-
-### InfluxDB v1
-
-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"

-    metrics:
-      influxDB: {}
-    ```

-    [metrics.influxDB]
-    ```
-
-    ```bash tab="CLI"
-    --metrics.influxDB=true
-    ```
-
-This configuration is now unsupported and would prevent Traefik to start.
-
-#### Remediation
-
-All InfluxDB v1 metrics provider related configuration should be removed from the static configuration.
-
-### Pilot
-
-Traefik Pilot is no longer available since October 4th, 2022.
-
-??? example "An example of v2 Pilot configuration"
-
-    ```yaml tab="File (YAML)"
-    pilot:

-        token=foobar
-    ```
-
-    ```bash tab="CLI"
-    --pilot.token=foobar
-    ```
-
-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.
-
-## Dynamic configuration
-
-### 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"

-  namespace: default
-
-spec:
-  routes:

-      syntax: v2
-      kind: Rule

-    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.
-
-## Operations
-
-### 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 (AccessLogs, Metrics and Tracing)
-
-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:

+## 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`
+- HTTP: `ReverseProxy read error during body copy: read tcp X.X.X.X:X->X.X.X.X:X: use of closed network connection`
+
+## v2.11.3
+
+### Connection headers
+
+In `v2.11.3`, the handling of the request Connection headers directives has changed to prevent any abuse.
+Before, Traefik removed any header listed in the Connection header just before forwarding the request to the backends.
+Now, Traefik removes the headers listed in the Connection header as soon as the request is handled.
+As a consequence, middlewares do not have access to those Connection headers,
+and a new option has been introduced to specify which ones could go through the middleware chain before being removed: `<entrypoint>.forwardedHeaders.connection`.
+
+Please check out the [entrypoint forwarded headers connection option configuration](../routing/entrypoints.md#forwarded-headers) documentation.
+
+## v2.11.14
+
+### X-Forwarded-Prefix
+
+In `v2.11.14`, the `X-Forwarded-Prefix` header is now handled like the other `X-Forwarded-*` headers: Traefik removes it when it's sent from an untrusted source.
+Please refer to the Forwarded headers [documentation](../routing/entrypoints.md#forwarded-headers) for more details.
+
+## v2.11.23
+
+### Request Path Sanitization
+
+Since `v2.11.23`, the incoming request path is now cleaned before being used to match the router rules and sent to the backends.
+Any `/../`, `/./` or duplicate slash segments in the request path is interpreted and/or collapsed.
+
+If you want to disable this behavior, you can set the [`sanitizePath` option](../routing/entrypoints.md#sanitizepath) to `false` in the entryPoint HTTP configuration.
+This can be useful when dealing with legacy clients that are not url-encoding data in the request path.
+For example, as base64 uses the “/” character internally,
+if it's not url encoded,
+it can lead to unsafe routing when the `sanitizePath` option is set to `false`.
+
+!!! warning "Security"
+
+    Setting the `sanitizePath` option to `false` is not safe.
+    Ensure every request is properly url encoded instead.

-## 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.
-
-Traefik supports these 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 supports these tracing with OpenTelemetry.
-
-Read the [Tracing documentation](./tracing/overview.md) to learn how to configure it.
