cloudflared-mirror/CHANGES.md

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

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. Equinox 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.

• 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.
• proxy-dns option now works in conjunction with running a named tunnel #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 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 was broken in 2021.2.5 and is now fixed again.

2021.2.5

New Features

• We introduce Cloudflare One Routing 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.
