+# Experimental: This is a new format for release notes. The format and availability is subject to change.
+
+## 2021.2.4
+
+### Bug Fixes
+- [configuration] fixes a case where `cloudflared` failed to read URLs in configuration files
+- [logging] cloudflared now logs reason for failed connections if the error is recoverable
+
+## 2021.2.3
+ 
+### Backward Incompatible Changes
+- [db-connect] Removes db-connect from `cloudflared`. 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
+- [TCP connects] Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318)
+ 
+### Improvements
+- [command line interface] Nested commands (such as cloudflared tunnel run) now consider CLI arguments even if they appear earlier in the command. E.g. `cloudflared --config config.yaml tunnel run` will now behave similarly to `cloudflared tunnel --config config.yaml run`
+ 
+### Bug Fixes
+- [dns-proxy] 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

-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 Argo Tunnel, a tunneling daemon that proxies any local webserver through the Cloudflare network. Extensive documentation can be found in the [Argo Tunnel section](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps) of the Cloudflare Docs.

-## Getting started
+## Before you get started

-    go install github.com/cloudflare/cloudflared/cmd/cloudflared
+Before you use Argo Tunnel, you'll need to complete a few steps in the Cloudflare dashboard. The website you add to Cloudflare will be used to route traffic to your Tunnel.

-User documentation for Argo Tunnel can be found at https://developers.cloudflare.com/argo-tunnel/
+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 Argo 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 that serve traffic for hostnames in your account.
+
+* Create a Tunnel with [these instructions](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/create-tunnel)
+* Route traffic to that Tunnel with [DNS records in Cloudflare](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/routing-to-tunnel/dns) or with a [Cloudflare Load Balancer](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/routing-to-tunnel/lb)
+
+## TryCloudflare
+
+Want to test Argo 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/trycloudflare).
+
+## Deprecated versions
+
+Cloudflare currently supports all versions of `cloudflared`. Starting on March 20, 2021, Cloudflare will no longer support versions released prior to 2020.5.1.
+
+All features available in versions released prior to 2020.5.1 are available in current versions. 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).
