Release 2022.6.2

This PR removes go-sumtype from cloudflared's build processes.

The value we see from analysing exhaustive match patterns in go is minimal (we can do this in code reviews) compared to using a tool that is unmaintained and (now broken) in Go 1.18.

We'd already been using the patched version here: https://github.com/sudarshan-reddy/go-sumtype because the original is broken for go tools > 1.16

-**Experimental**: This is a new format for release notes. The format and availability is subject to change.
+## 2022.4.0
+### Bug Fixes
+- `cloudflared tunnel run` no longer logs the Tunnel token or JSON credentials in clear text as those are the secret
+that allows to run the Tunnel.
+
+## 2022.3.4
+### New Features
+- It is now possible to retrieve the credentials that allow to run a Tunnel in case you forgot/lost them. This is
+achievable with: `cloudflared tunnel token --cred-file /path/to/file.json TUNNEL`. This new feature only works for
+Tunnels created with cloudflared version 2022.3.0 or more recent.
+
+### Bug Fixes
+- `cloudflared service install` now starts the underlying agent service on Linux operating system (similarly to the
+behaviour in Windows and MacOS).
+
+## 2022.3.3
+### Bug Fixes
+- `cloudflared service install` now starts the underlying agent service on Windows operating system (similarly to the
+behaviour in MacOS).
+
+## 2022.3.1
+### Bug Fixes
+- Various fixes to the reliability of `quic` protocol, including an edge case that could lead to cloudflared crashing.
+
+## 2022.3.0
+### New Features
+- It is now possible to configure Ingress Rules to point to an origin served by unix socket with either HTTP or HTTPS.
+If the origin starts with `unix:/` then we assume HTTP (existing behavior). Otherwise, the origin can start with
+`unix+tls:/` for HTTPS.
+
+## 2022.2.1
+### New Features
+- This project now has a new LICENSE that is more compliant with open source purposes.
+
+### Bug Fixes
+- Various fixes to the reliability of `quic` protocol.
+
+## 2022.1.3
+### New Features
+- New `cloudflared tunnel vnet` commands to allow for private routing to be virtualized. This means that the same CIDR
+can now be used to point to two different Tunnels with `cloudflared tunnel route ip` command. More information will be
+made available on blog.cloudflare.com and developers.cloudflare.com/cloudflare-one once the feature is globally available.
+
+### Bug Fixes
+- Correctly handle proxying UDP datagrams with no payload.
+- Bug fix for origins that use Server-Sent Events (SSE).
+
+## 2022.1.0
+### Improvements
+- If a specific `protocol` property is defined (e.g. for `quic`), cloudflared no longer falls back to an older protocol
+(such as `http2`) in face of connectivity errors. This is important because some features are only supported in a specific
+protocol (e.g. UDP proxying only works for `quic`). Hence, if a user chooses a protocol, cloudflared now adheres to it
+no matter what.
+
+### Bug Fixes
+- Stopping cloudflared running with `quic` protocol now respects graceful shutdown.

-		specified port where it can be served.
+		Description: `    Cloudflare Tunnel allows to expose private services without opening any ingress port on this machine. It can expose:
+  A) Locally reachable HTTP-based private services to the Internet on DNS with Cloudflare as authority (which you can
+then protect with Cloudflare Access).
+  B) Locally reachable TCP/UDP-based private services to Cloudflare connected private users in the same account, e.g.,
+those enrolled to a Zero Trust WARP Client.
 
-		This feature requires your Cloudflare account be subscribed to the Cloudflare Smart Routing feature.
+You can manage your Tunnels via dash.teams.cloudflare.com. This approach will only require you to run a single command
+later in each machine where you wish to run a Tunnel.
 
-		To use, begin by calling login to download a certificate:
+Alternatively, you can manage your Tunnels via the command line. Begin by obtaining a certificate to be able to do so:
 
-			$ cloudflared tunnel login
+	$ cloudflared tunnel login
 
-		With your certificate installed you can then launch your first tunnel,
-		replacing my.site.com with a subdomain of your site:
+With your certificate installed you can then get started with Tunnels:
 
-			$ cloudflared tunnel --hostname my.site.com --url http://localhost:8080
+	$ cloudflared tunnel create my-first-tunnel
+	$ cloudflared tunnel route dns my-first-tunnel my-first-tunnel.mydomain.com
+	$ cloudflared tunnel run --hello-world my-first-tunnel
 
-		If you have a web server running on port 8080 (in this example), it will be available on
-		the internet!`,
+You can now access my-first-tunnel.mydomain.com and be served an example page by your local cloudflared process.
+
+For exposing local TCP/UDP services by IP to your privately connected users, check out:
+
+	$ cloudflared tunnel route ip --help
+
+See https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/ for more info.`,
