Release 2022.1.0

This parameterizes relevant component tests by transport protocol
where applicable.
The motivation is to have coverage for (graceful or not) shutdown
that was broken in QUIC. That logic (as well as reconnect) is
different depending on the transport, so we should have it
parameterized. In fact, the test is failing for QUIC (and passing
for others) right now, which is expected until we roll out some
edge fixes for QUIC. So we could have caught this earlier on.

+**Experimental**: This is a new format for release notes. The format and availability is subject to change.
+
+## 2021.12.2
+### Bug Fixes
+- Fix logging when `quic` transport is used and UDP traffic is proxied.
+- FIPS compliant cloudflared binaries will now be released as separate artifacts. Recall that these are only for linux
+and amd64.
+
+## 2021.12.1
+### Bug Fixes
+ - Fixes Github issue #530 where cloudflared 2021.12.0 could not reach origins that were HTTPS and using certain encryption
+methods forbidden by FIPS compliance (such as Let's Encrypt certificates). To address this fix we have temporarily reverted
+FIPS compliance from amd64 linux binaries that was recently introduced (or fixed actually as it was never working before).
+
+## 2021.12.0
+### New Features
+- Cloudflared binary released for amd64 linux is now FIPS compliant.
+
+### Improvements
+- Logging about connectivity to Cloudflare edge now only yields `ERR` level logging if there are no connections to
+Cloudflare edge that are active. Otherwise it logs `WARN` level.
+ 
+### Bug Fixes
+- Fixes Github issue #501.
+
+## 2021.11.0
+### Improvements
+- Fallback from `protocol:quic` to `protocol:http2` immediately if UDP connectivity isn't available. This could be because of a firewall or 
+egress rule.
+
+## 2021.10.4
+### Improvements
+- Collect quic transport metrics on RTT, packets and bytes transferred.
+
+### Bug Fixes
+- Fix race condition that was writing to the connection after the http2 handler returns.
+
+## 2021.9.2
+
+### New features
+- `cloudflared` can now run with `quic` as the underlying tunnel transport protocol. To try it, change or add "protocol: quic" to your config.yml file or
+run cloudflared with the `--protocol quic` flag. e.g:
+    `cloudflared tunnel --protocol quic run <tunnel-name>`
+
+### Bug Fixes
+- Fixed some generic transport bugs in `quic` mode. It's advised to upgrade to at least this version (2021.9.2) when running `cloudflared`
+with `quic` protocol.
+- `cloudflared` docker images will now show version.
+
+
+## 2021.8.4
+### Improvements
+- Temporary tunnels (those hosted on trycloudflare.com that do not require a Cloudflare login) now run as Named Tunnels
+underneath. We recall that these tunnels should not be relied upon for production usage as they come with no guarantee
+of uptime. Previous cloudflared versions will soon be unable to run legacy temporary tunnels and will require an update
+(to this version or more recent).
+
+## 2021.8.2
+### Improvements
+- Because Equinox os shutting down, all cloudflared releases are now present [here](https://github.com/cloudflare/cloudflared/releases).
+[Equinox](https://dl.equinox.io/cloudflare/cloudflared/stable) will no longer receive updates. 
+
+## 2021.8.0
+### Bug fixes
+- Prevents tunnel from accidentally running when only proxy-dns should run. 
+
+### Improvements
+- If auto protocol transport lookup fails, we now default to a transport instead of not connecting.
+
+## 2021.6.0
+### Bug Fixes
+- Fixes a http2 transport (the new default for Named Tunnels) to work with unix socket origins.
+
+
+## 2021.5.10
+### Bug Fixes
+- Fixes a memory leak in h2mux transport that connects cloudflared to Cloudflare edge.
+
+
+## 2021.5.9
+### New Features
+- Uses new Worker based login helper service to facilitate token exchange in cloudflared flows.
+
+### Bug Fixes
+- Fixes Centos-7 builds.
+
+## 2021.5.8
+### New Features
+- When creating a DNS record to point a hostname at a tunnel, you can now use --overwrite-dns to overwrite any existing
+  DNS records with that hostname. This works both when using the CLI to provision DNS, as well as when starting an adhoc
+  named tunnel, e.g.:
+  - `cloudflared tunnel route dns --overwrite-dns foo-tunnel foo.example.com`
+  - `cloudflared tunnel --overwrite-dns --name foo-tunnel --hostname foo.example.com`
+
+## 2021.5.7
+### New Features
+- Named Tunnels will automatically select the protocol to connect to Cloudflare's edge network.
+
+## 2021.5.0
+
+### New Features
+- It is now possible to run the same tunnel using more than one `cloudflared` instance. This is a server-side change and
+  is compatible with any client version that uses Named Tunnels.
+
+  To get started, visit our [developer documentation](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/run-tunnel/deploy-cloudflared-replicas).
+- `cloudflared tunnel ingress validate` will now warn about unused keys in your config file. This is helpful for
+  detecting typos in your config.
+- If `cloudflared` detects it is running inside a Linux container, it will limit itself to use only the number of CPUs
+  the pod has been granted, instead of trying to use every CPU available.
+
+## 2021.4.0
+
+### Bug Fixes
+
+- Fixed proxying of websocket requests to avoid possibility of losing initial frames that were sent in the same TCP
+  packet as response headers [#345](https://github.com/cloudflare/cloudflared/issues/345).
+- `proxy-dns` option now works in conjunction with running a named tunnel [#346](https://github.com/cloudflare/cloudflared/issues/346).
+
+## 2021.3.6
+
+### Bug Fixes
+
+- Reverted 2021.3.5 improvement to use HTTP/2 in a best-effort manner between cloudflared and origin services because
+  it was found to break in some cases.
+
+## 2021.3.5
+
+### Improvements
+
+ - HTTP/2 transport is now always chosen if origin server supports it and the service url scheme is HTTPS.
+   This was previously done in a best attempt manner.
+
+### Bug Fixes
+
+ - The MacOS binaries were not successfully released in 2021.3.3 and 2021.3.4. This release is aimed at addressing that.
+
+## 2021.3.3
+
+### Improvements
+
+- Tunnel create command, as well as, running ad-hoc tunnels using `cloudflared tunnel -name NAME`, will not overwrite
+  existing files when writing tunnel credentials.
+
+### Bug Fixes
+
+- Tunnel create and delete commands no longer use path to credentials from the configuration file.
+  If you need ot place tunnel credentials file at a specific location, you must use `--credentials-file` flag.
+- Access ssh-gen creates properly named keys for SSH short lived certs.
+
+
+## 2021.3.2
+
+### New Features
+
+- It is now possible to obtain more detailed information about the cloudflared connectors to Cloudflare Edge via
+  `cloudflared tunnel info <name/uuid>`. It is possible to sort the output as well as output in different formats,
+  such as: `cloudflared tunnel info --sort-by version --invert-sort --output json <name/uuid>`.
+  You can obtain more information via `cloudflared tunnel info --help`.
+
+### Bug Fixes
+
+- Don't look for configuration file in default paths when `--config FILE` flag is present after `tunnel` subcommand.
+- cloudflared access token command now functions correctly with the new token-per-app change from 2021.3.0.
+
+
+## 2021.3.0
+
+### New Features
+
+- [Cloudflare One Routing](https://developers.cloudflare.com/cloudflare-one/tutorials/warp-to-tunnel) specific commands
+  now show up in the `cloudflared tunnel route --help` output.
+- There is a new ingress type that allows cloudflared to proxy SOCKS5 as a bastion. You can use it with an ingress
+  rule by adding `service: socks-proxy`. Traffic is routed to any destination specified by the SOCKS5 packet but only
+  if allowed by a rule. In the following example we allow proxying to a certain CIDR but explicitly forbid one address
+  within it:
+```
+ingress:
+  - hostname: socks.example.com
+    service: socks-proxy
+    originRequest:
+      ipRules:
+        - prefix: 192.168.1.8/32
+          allow: false
+        - prefix: 192.168.1.0/24
+          ports: [80, 443]
+          allow: true
+```
+
+
+### Improvements
+
+- Nested commands, such as `cloudflared tunnel run`, now consider CLI arguments even if they appear earlier on the
+  command. For instance, `cloudflared --config config.yaml tunnel run` will now behave the same as
+  `cloudflared tunnel --config config.yaml run`
+- Warnings are now shown in the output logs whenever cloudflared is running without the most recent version and
+  `no-autoupdate` is `true`.
+- Access tokens are now stored per Access App instead of per request path. This decreases the number of times that the
+  user is required to authenticate with an Access policy redundantly.
+
+### Bug Fixes
+
+- GitHub [PR #317](https://github.com/cloudflare/cloudflared/issues/317) was broken in 2021.2.5 and is now fixed again.
+
+## 2021.2.5
+
+### New Features
+
+- We introduce [Cloudflare One Routing](https://developers.cloudflare.com/cloudflare-one/tutorials/warp-to-tunnel) in
+  beta mode. Cloudflare customer can now connect users and private networks with RFC 1918 IP addresses via the
+  Cloudflare edge network. Users running Cloudflare WARP client in the same organization can connect to the services
+  made available by Argo Tunnel IP routes. Please share your feedback in the GitHub issue tracker.
+
+## 2021.2.4
+
+### Bug Fixes
+
+- Reverts the Improvement released in 2021.2.3 for CLI arguments as it introduced a regression where cloudflared failed
+  to read URLs in configuration files.
+- cloudflared now logs the reason for failed connections if the error is recoverable.
+
+## 2021.2.3
+
+### Backward Incompatible Changes
+
+- Removes db-connect. The Cloudflare Workers product will continue to support db-connect implementations with versions
+  of cloudflared that predate this release and include support for db-connect.
+
+### New Features
+
+- Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318).
+
+### Improvements
+
+- (reverted) Nested command line argument handling.
+
+### Bug Fixes
+
+- The maximum number of upstream connections is now limited by default which should fix reported issues of cloudflared
+  exhausting CPU usage when faced with connectivity issues.

-# Argo Tunnel client
+# Cloudflare Tunnel client
 
-Contains the command-line client and its libraries for Argo Tunnel, a tunneling daemon that proxies any local webserver through the Cloudflare network.
+Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins.
+This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you
+via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible.
+Extensive documentation can be found in the [Cloudflare Tunnel section](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps) of the Cloudflare Docs.
+All usages related with proxying to your origins are available under `cloudflared tunnel help`.
 
-## Getting started
+You can also use `cloudflared` to access Tunnel origins (that are protected with `cloudflared tunnel`) for TCP traffic
+at Layer 4 (i.e., not HTTP/websocket), which is relevant for use cases such as SSH, RDP, etc.
+Such usages are available under `cloudflared access help`.
 
-    go install github.com/cloudflare/cloudflared/cmd/cloudflared
+You can instead use [WARP client](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/configuration/private-networks)
+to access private origins behind Tunnels for Layer 4 traffic without requiring `cloudflared access` commands on the client side.
 
-User documentation for Argo Tunnel can be found at https://developers.cloudflare.com/argo-tunnel/
+
+## Before you get started
+
+Before you use Cloudflare Tunnel, you'll need to complete a few steps in the Cloudflare dashboard: you need to add a
+website to your Cloudflare account. Note that today it is possible to use Tunnel without a website (e.g. for private
+routing), but for legacy reasons this requirement is still necessary:
+1. [Add a website to Cloudflare](https://support.cloudflare.com/hc/en-us/articles/201720164-Creating-a-Cloudflare-account-and-adding-a-website)
+2. [Change your domain nameservers to Cloudflare](https://support.cloudflare.com/hc/en-us/articles/205195708)
+
+
+## Installing `cloudflared`
+
+Downloads are available as standalone binaries, a Docker image, and Debian, RPM, and Homebrew packages. You can also find releases here on the `cloudflared` GitHub repository.
+
+* You can [install on macOS](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/installation#macos) via Homebrew or by downloading the [latest Darwin amd64 release](https://github.com/cloudflare/cloudflared/releases)
+* Binaries, Debian, and RPM packages for Linux [can be found here](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/installation#linux)
+* A Docker image of `cloudflared` is [available on DockerHub](https://hub.docker.com/r/cloudflare/cloudflared)
+* You can install on Windows machines with the [steps here](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/installation#windows)
+
+User documentation for Cloudflare Tunnel can be found at https://developers.cloudflare.com/cloudflare-one/connections/connect-apps
+
+
+## Creating Tunnels and routing traffic
+
+Once installed, you can authenticate `cloudflared` into your Cloudflare account and begin creating Tunnels to serve traffic to your origins.
+
+* Create a Tunnel with [these instructions](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/create-tunnel)
+* Route traffic to that Tunnel:
+  * Via public [DNS records in Cloudflare](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/routing-to-tunnel/dns)
+  * Or via a public hostname guided by a [Cloudflare Load Balancer](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/routing-to-tunnel/lb)
+  * Or from [WARP client private traffic](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/configuration/private-networks)
+
+
+## TryCloudflare
+
+Want to test Cloudflare Tunnel before adding a website to Cloudflare? You can do so with TryCloudflare using the documentation [available here](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/run-tunnel/trycloudflare).
+
+## Deprecated versions
+
+Cloudflare currently supports versions of `cloudflared` 2020.5.1 and later. Breaking changes unrelated to feature availability may be introduced that will impact versions released prior to 2020.5.1. You can read more about upgrading `cloudflared` in our [developer documentation](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/installation#updating-cloudflared).

+		    service: https://localhost:8001
+		  - hostname: *
+		    service: https://localhost:8002
+
+		To ensure cloudflared can route all incoming requests, the last rule must be a catch-all
+		rule that matches all traffic. You can validate these rules with the 'ingress validate'
