-## 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.

-## Why does Let's Encrypt wildcard certificate renewal/generation with DNS challenge fail?
-
-If you're trying to renew wildcard certificates, with DNS challenge,
-and you're getting errors such as:
-
-```txt
-msg="Error renewing certificate from LE: {example.com [*.example.com]}"
-providerName=letsencrypt.acme error="error: one or more domains had a problem:
-[example.com] acme: error presenting token: gandiv5: unexpected authZone example.com. for fqdn example.com."
-```
-
-then it could be due to `CNAME` support.
-
-In which case, you should make sure your infrastructure is properly set up for a
-`DNS` challenge that does not rely on `CNAME`, and you should try disabling `CNAME` support with:
-
-```bash
-LEGO_DISABLE_CNAME_SUPPORT=true

+# 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) that is meant to be secured with SPIFFE must [explicitly](../routing/services/index.md#spiffe) enable it.
+
+!!! 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`.
+
+## Configuration Example

-As a proxy, the default behavior should be to leave the header alone,

-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).

+
+# 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.
+
+## IPWhiteList
+
+In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
+
+## gRPC Metrics
+
+In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.  
+
+## Deprecated Options Removal
+
+- The `pilot` option has been removed from the static configuration.
+- The `tracing.datadog.globaltag` option has been removed.
+- The `namespace` option of Consul, Consul Catalog and Nomad providers has been removed.
+- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Marathon, 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.
+
+## Matchers
+
+In v3, the `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
+
+`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 `Headers`, `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.
+
+## 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.
+
+## HTTP/3
+
+In v3, HTTP/3 is no longer an experimental feature.
+The `experimental.http3` option has been removed from the static configuration.

+### Nomad Namespace

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

+
+# OpenTelemetry
+
+To enable the OpenTelemetry tracer:
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry: {}
+```
+
+```toml tab="File (TOML)"
+[tracing]
+  [tracing.openTelemetry]
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry=true
+```
+
+!!! info "The OpenTelemetry trace reporter will export traces to the collector using HTTP by default, see the [gRPC Section](#grpc-configuration) to use gRPC."
+
+!!! info "Trace sampling"
+
+	By default, the OpenTelemetry trace reporter will sample 100% of traces.
+	See [OpenTelemetry's SDK configuration](https://opentelemetry.io/docs/reference/specification/sdk-environment-variables/#general-sdk-configuration) to customize the sampling strategy.
+
+#### `address`
+
+_Required, Default="localhost:4318", Format="`<host>:<port>`"_
+
+Address of the OpenTelemetry Collector to send spans to.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    address: localhost:4318
+```
+
+```toml tab="File (TOML)"
+[tracing]
+  [tracing.openTelemetry]
+    address = "localhost:4318"
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.address=localhost:4318
+```
+
+#### `headers`
+
+_Optional, Default={}_
+
+Additional headers sent with spans by the reporter to the OpenTelemetry Collector.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    headers:
+      foo: bar
+      baz: buz
+```
+
+```toml tab="File (TOML)"
+[tracing]
+  [tracing.openTelemetry.headers]
+    foo = "bar"
+    baz = "buz"
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.headers.foo=bar --tracing.openTelemetry.headers.baz=buz
+```
+
+#### `insecure`
+
+_Optional, Default=false_
+
+Allows reporter to send spans to the OpenTelemetry Collector without using a secured protocol.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    insecure: true
+```
+
+```toml tab="File (TOML)"
+[tracing]
+  [tracing.openTelemetry]
+    insecure = true
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.insecure=true
+```
+
+#### `path`
+
+_Required, Default="/v1/traces"_
+
+Allows to override the default URL path used for sending traces.
+This option has no effect when using gRPC transport.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    path: /foo/v1/traces
+```
+
+```toml tab="File (TOML)"
+[tracing]
+  [tracing.openTelemetry]
+    path = "/foo/v1/traces"
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.path=/foo/v1/traces
+```
+
+#### `tls`
+
+_Optional_
+
+Defines the TLS configuration used by the reporter to send spans to the OpenTelemetry Collector.
+
+##### `ca`
+
+_Optional_
+
+`ca` is the path to the certificate authority used for the secure connection to the OpenTelemetry Collector,
+it defaults to the system bundle.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    tls:
+      ca: path/to/ca.crt
+```
+
+```toml tab="File (TOML)"

+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.tls.ca=path/to/ca.crt
+```
+
+##### `cert`
+
+_Optional_
+
+`cert` is the path to the public certificate used for the secure connection to the OpenTelemetry Collector.
+When using this option, setting the `key` option is required.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    tls:
+      cert: path/to/foo.cert
+      key: path/to/foo.key
+```
+
+```toml tab="File (TOML)"
+[tracing.openTelemetry.tls]
+  cert = "path/to/foo.cert"
+  key = "path/to/foo.key"
+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.tls.cert=path/to/foo.cert
+--tracing.openTelemetry.tls.key=path/to/foo.key
+```
+
+##### `key`
+
+_Optional_
+
+`key` is the path to the private key used for the secure connection to the OpenTelemetry Collector.
+When using this option, setting the `cert` option is required.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    tls:
+      cert: path/to/foo.cert
+      key: path/to/foo.key

+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.tls.cert=path/to/foo.cert
+--tracing.openTelemetry.tls.key=path/to/foo.key
+```
+
+##### `insecureSkipVerify`
+
+_Optional, Default=false_
+
+If `insecureSkipVerify` is `true`,
+the TLS connection to the OpenTelemetry Collector accepts any certificate presented by the server regardless of the hostnames it covers.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    tls:
+      insecureSkipVerify: true
+```
+
+```toml tab="File (TOML)"

+```
+
+```bash tab="CLI"
+--tracing.openTelemetry.tls.insecureSkipVerify=true
+```
+
+#### gRPC configuration
+
+_Optional_
+
+This instructs the reporter to send spans to the OpenTelemetry Collector using gRPC.
+
+```yaml tab="File (YAML)"
+tracing:
+  openTelemetry:
+    grpc: {}
+```
+
+```toml tab="File (TOML)"

-!!! important "Non-ASCII Domain Names"
+!!! tip "Backticks or Quotes?"
 
-    Non-ASCII characters are not supported in `Host` and `HostRegexp` expressions, and by doing so the associated router will be invalid.
+    To set the value of a rule, use [backticks](https://en.wiktionary.org/wiki/backtick) ``` ` ``` or escaped double-quotes `\"`.
-    For the `Host` expression, domain names containing non-ASCII characters must be provided as punycode encoded values ([rfc 3492](https://tools.ietf.org/html/rfc3492)).
+
-    As well, when using the `HostRegexp` expressions, in order to match domain names containing non-ASCII characters, the regular expression should match a punycode encoded domain name.
+    Single quotes `'` are not accepted since the values are [Go's String Literals](https://golang.org/ref/spec#String_literals).
 
 !!! important "Regexp Syntax"
 
-    `HostRegexp`, `PathPrefix`, and `Path` accept an expression with zero or more groups enclosed by curly braces, which are called named regexps.
+    Matchers that accept a regexp as their value use a [Go](https://golang.org/pkg/regexp/) flavored syntax.
-    Named regexps, of the form `{name:regexp}`, are the only expressions considered for regexp matching.
-    The regexp name (`name` in the above example) is an arbitrary value, that exists only for historical reasons.
 
-    Any `regexp` supported by [Go's regexp package](https://golang.org/pkg/regexp/) may be used.
+!!! info "Expressing Complex Rules Using Operators and Parenthesis"

-
-!!! info "Combining Matchers Using Operators and Parenthesis"
 
     The usual AND (`&&`) and OR (`||`) logical operators can be used, with the expected precedence rules,
     as well as parentheses.

-    One can invert a matcher by using the `!` operator.
+    The following rule matches requests where:
 
-!!! important "Rule, Middleware, and Services"
+    - either host is `example.com` OR,
+    - host is `example.org` AND path is NOT `/traefik`
 
-    The rule is evaluated "before" any middleware has the opportunity to work, and "before" the request is forwarded to the service.
+    ```yaml
+    Host(`example.com`) || (Host(`example.org`) && !Path(`/traefik`))
+    ```
 
-!!! info "Path Vs PathPrefix"
+#### Header and HeaderRegexp
 
-    Use `Path` if your service listens on the exact path only. For instance, ```Path(`/products`)``` would match `/products` but not `/products/shoes`.
+The `Header` and `HeaderRegexp` matchers allow to match requests that contain specific header.
 
-    Use a `*Prefix*` matcher if your service listens on a particular base path but also serves requests on sub-paths.
+!!! example "Examples"
-    For instance, ```PathPrefix(`/products`)``` would match `/products` and `/products/shoes`,
-    as well as `/productsforsale`, and `/productsforsale/shoes`.
-    Since the path is forwarded as-is, your service is expected to listen on `/products`.
 
-!!! info "ClientIP matcher"
+    Match requests with a `Content-Type` header set to `application/yaml`:
 
-    The `ClientIP` matcher will only match the request client IP and does not use the `X-Forwarded-For` header for matching.
+    ```yaml
+    Header(`Content-Type`, `application/yaml`)
+    ```
+
+    Match requests with a `Content-Type` header set to either `application/json` or `application/yaml`:
+
+    ```yaml
+    HeaderRegexp(`Content-Type`, `^application/(json|yaml)$`)
+    ```
+
+    To match headers [case-insensitively](https://en.wikipedia.org/wiki/Case_sensitivity), use the `(?i)` option:
+
+    ```yaml
+    HeaderRegexp(`Content-Type`, `(?i)^application/(json|yaml)$`)
+    ```
+
+#### Host and HostRegexp
+
+The `Host` and `HostRegexp` matchers allow to match requests that are targeted to a given host.
+
+These matchers do not support non-ASCII characters, use punycode encoded values ([rfc 3492](https://tools.ietf.org/html/rfc3492)) to match such domains.
+
+If no Host is set in the request URL (e.g., it's an IP address), these matchers will look at the `Host` header.
+
+These matchers will match the request's host in lowercase.
+
+!!! example "Examples"
+
+    Match requests with `Host` set to `example.com`:
+
+    ```yaml
+    Host(`example.com`)
+    ```
+
+    Match requests sent to any subdomain of `example.com`:
+
+    ```yaml
+    HostRegexp(`^.+\.example\.com$`)
+    ```
+
+    Match requests with `Host` set to either `example.com` or `example.org`:
+
+    ```yaml
+    HostRegexp(`^example\.(com|org)$`)
+    ```
+
+    To match domains [case-insensitively](https://en.wikipedia.org/wiki/Case_sensitivity), use the `(?i)` option:
+
+    ```yaml
+    HostRegexp(`(?i)^example\.(com|org)$`)
+    ```
+
+#### Method
+
+The `Method` matchers allows to match requests sent with the given method.
+
+!!! example "Example"
+
+    Match `OPTIONS` requests:
+
+    ```yaml
+    Method(`OPTIONS`)
+    ```
+
+#### Path, PathPrefix, and PathRegexp
+
+These matchers allow matching requests based on their URL path.
+
+For exact matches, use `Path` and its prefixed alternative `PathPrefix`, for regexp matches, use `PathRegexp`.
+
+Path are always starting with a `/`, except for `PathRegexp`.
+
+!!! example "Examples"
+
+    Match `/products` but neither `/products/shoes` nor `/products/`:
+
+    ```yaml
+    Path(`/products`)
+    ```
+
+    Match `/products` as well as everything under `/products`,
+    such as `/products/shoes`, `/products/` but also `/products-for-sale`:
+
+    ```yaml
+    PathPrefix(`/products`)
+    ```
+
+    Match both `/products/shoes` and `/products/socks` with and ID like `/products/shoes/57`:
+
+    ```yaml
+    PathRegexp(`^/products/(shoes|socks)/[0-9]+$`)
+    ```
+
+    Match requests with a path ending in either `.jpeg`, `.jpg` or `.png`:
+
+    ```yaml
+    PathRegexp(`\.(jpeg|jpg|png)$`)
+    ```
+
+    Match `/products` as well as everything under `/products`,
+    such as `/products/shoes`, `/products/` but also `/products-for-sale`,
+    [case-insensitively](https://en.wikipedia.org/wiki/Case_sensitivity):
+
+    ```yaml
+    HostRegexp(`(?i)^/products`)
+    ```
+
+#### Query and QueryRegexp
+
+The `Query` and `QueryRegexp` matchers allow to match requests based on query parameters.
+
+!!! example "Examples"
+
+    Match requests with a `mobile` query parameter set to `true`, such as in `/search?mobile=true`:
+
+    ```yaml
+    Query(`mobile`, `true`)
+    ```
+
+    To match requests with a query parameter `mobile` that has no value, such as in `/search?mobile`, use:
+
+    ```yaml
+    Query(`mobile`)
+    ```
+
+    Match requests with a `mobile` query parameter set to either `true` or `yes`:
+
+    ```yaml
+    QueryRegexp(`mobile`, `^(true|yes)$`)
+    ```
+
+    Match requests with a `mobile` query parameter set to any value (including the empty value):
+
+    ```yaml
+    QueryRegexp(`mobile`, `^.*$`)
+    ```
+
+    To match query parameters [case-insensitively](https://en.wikipedia.org/wiki/Case_sensitivity), use the `(?i)` option:
+
+    ```yaml
+    QueryRegexp(`mobile`, `(?i)^(true|yes)$`)
+    ```
+
+#### ClientIP
+
+The `ClientIP` matcher allows matching requests sent from the given client IP.
+
+It only matches the request client IP and does not use the `X-Forwarded-For` header for matching.
+
+!!! example "Examples"
+
+    Match requests coming from a given IP:
+
+    ```yaml tab="IPv4"
+    ClientIP(`10.76.105.11`)
+    ```
+
+    ```yaml tab="IPv6"
+    ClientIP(`::1`)
+    ```
+
+    Match requests coming from a given subnet:
+
+    ```yaml tab="IPv4"
+    ClientIP(`192.168.1.0/24`)
+    ```
+
+    ```yaml tab="IPv6"
+    ClientIP(`fe80::/10`)
+    ```

+
+    Traefik supports the Postgres STARTTLS protocol,
+    which allows TLS routing for Postgres connections.
+
+    To do so, Traefik reads the first bytes sent by a Postgres client,
+    identifies if they correspond to the message of a STARTTLS negotiation,
+    and, if so, acknowledges and signals the client that it can start the TLS handshake.
+
+    Please note/remember that there are subtleties inherent to STARTTLS in whether

+    `sslmode` value in the client configuration (and on the server authentication
