## 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 when using the CLI to provision DNS, and when starting an adhoc tunnel, e.g.
- `cloudflared route --overwrite-dns dns foo foo.example.com`
- `cloudflared tunnel --overwrite-dns --name foo --hostname foo.example.com`
2021-05-17 14:48:07 +00:00
## 2021.5.7
### New Features
- Named Tunnels will automatically select the protocol to connect to Cloudflare's edge network.
2021-05-17 02:03:59 +00:00
## 2021.5.0
2021-04-29 15:41:18 +00:00
### 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 ).
2021-05-11 02:47:59 +00:00
- `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
2021-04-02 06:10:43 +00:00
### 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 ).
2021-04-07 16:58:22 +00:00
- `proxy-dns` option now works in conjunction with running a named tunnel [#346 ](https://github.com/cloudflare/cloudflared/issues/346 ).
2021-04-02 06:10:43 +00:00
2021-03-31 07:20:03 +00:00
## 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.
2021-03-26 18:13:37 +00:00
## 2021.3.5
2021-03-26 09:45:26 +00:00
2021-03-26 18:13:37 +00:00
### Improvements
2021-03-26 09:45:26 +00:00
- 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
2021-03-26 18:13:37 +00:00
- The MacOS binaries were not successfully released in 2021.3.3 and 2021.3.4. This release is aimed at addressing that.
2021-03-26 09:45:26 +00:00
2021-03-25 16:17:10 +00:00
## 2021.3.3
2021-03-24 02:52:14 +00:00
### Improvements
2021-03-24 03:32:40 +00:00
- Tunnel create command, as well as, running ad-hoc tunnels using `cloudflared tunnel -name NAME` , will not overwrite
2021-04-29 15:41:18 +00:00
existing files when writing tunnel credentials.
2021-03-24 02:52:14 +00:00
### 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.
2021-03-25 16:17:10 +00:00
- Access ssh-gen creates properly named keys for SSH short lived certs.
2021-03-24 02:52:14 +00:00
2021-03-23 15:31:46 +00:00
## 2021.3.2
2021-02-05 01:44:03 +00:00
### New Features
2021-03-15 18:30:17 +00:00
- 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` .
2021-02-05 01:44:03 +00:00
### Bug Fixes
- Don't look for configuration file in default paths when `--config FILE` flag is present after `tunnel` subcommand.
2021-03-23 15:31:46 +00:00
- cloudflared access token command now functions correctly with the new token-per-app change from 2021.3.0.
2021-02-05 01:44:03 +00:00
2021-03-15 10:08:04 +00:00
## 2021.3.0
2021-02-23 19:48:32 +00:00
### New Features
2021-02-26 09:50:19 +00:00
- [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.
2021-03-15 10:08:04 +00:00
- 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
```
2021-04-29 15:41:18 +00:00
2021-02-23 19:48:32 +00:00
### 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`
2021-02-28 23:24:38 +00:00
- Warnings are now shown in the output logs whenever cloudflared is running without the most recent version and
`no-autoupdate` is `true` .
2021-03-15 10:08:04 +00:00
- 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.
2021-02-23 19:48:32 +00:00
### Bug Fixes
2021-03-09 17:16:17 +00:00
- GitHub [PR #317 ](https://github.com/cloudflare/cloudflared/issues/317 ) was broken in 2021.2.5 and is now fixed again.
2021-02-23 17:14:08 +00:00
## 2021.2.5
### New Features
2021-02-23 19:48:32 +00:00
- 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.
2021-02-23 09:58:39 +00:00
2021-02-23 12:33:37 +00:00
## 2021.2.4
### Bug Fixes
2021-02-23 17:14:08 +00:00
2021-02-23 19:48:32 +00:00
- 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.
2021-02-23 12:33:37 +00:00
2021-02-23 09:58:39 +00:00
## 2021.2.3
2021-02-23 19:48:32 +00:00
2021-02-23 09:58:39 +00:00
### Backward Incompatible Changes
2021-02-23 19:48:32 +00:00
- 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.
2021-02-23 09:58:39 +00:00
### New Features
2021-02-23 19:48:32 +00:00
2021-02-23 17:14:08 +00:00
- Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318).
2021-02-23 19:48:32 +00:00
2021-02-23 09:58:39 +00:00
### Improvements
2021-02-23 19:48:32 +00:00
- (reverted) Nested command line argument handling.
2021-02-23 09:58:39 +00:00
### Bug Fixes
2021-02-23 19:48:32 +00:00
- 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.
