 **Experimental**: This is a new format for release notes. The format and availability is subject to change.

+## 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.

Igor Postelnik	8ca0d86c85	TUN-3863: Consolidate header handling logic in the connection package; move headers definitions from h2mux to packages that manage them; cleanup header conversions All header transformation code from h2mux has been consolidated in the connection package since it's used by both h2mux and http2 logic. Exported headers used by proxying between edge and cloudflared so then can be shared by tunnel service on the edge. Moved access-related headers to corresponding packages that have the code that sets/uses these headers. Removed tunnel hostname tracking from h2mux since it wasn't used by anything. We will continue to set the tunnel hostname header from the edge for backward compatibilty, but it's no longer used by cloudflared. Move bastion-related logic into carrier package, untangled dependencies between carrier, origin, and websocket packages.	2021-03-29 21:57:56 +00:00
