+## 2023.3.2
+### Notices
+- Due to the nature of QuickTunnels (https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/do-more-with-tunnels/trycloudflare/) and its intended usage for testing and experiment of Cloudflare Tunnels, starting from 2023.3.2, QuickTunnels only make a single connection to the edge. If users want to use Tunnels in a production enverionment, they should move to Named Tunnels instead. (https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/remote/#set-up-a-tunnel-remotely-dashboard-setup)
+
+## 2023.3.1
+### Breaking Change
+- Running a tunnel without ingress rules defined in configuration file nor from the CLI flags will no longer provide a default ingress rule to localhost:8080 and instead will return HTTP response code 503 for all incoming HTTP requests.
+
+### Security Fixes
+- Windows 32 bit machines MSI now defaults to Program Files to install cloudflared. (See CVE-2023-1314). The cloudflared client itself is unaffected. This just changes how the installer works on 32 bit windows machines.
+
+### Bug Fixes
+- Fixed a bug that would cause running tunnel on Bastion mode and without ingress rules to crash.
+
+## 2023.2.2
+### Notices
+- Legacy tunnels were officially deprecated on December 1, 2022. Starting with this version, cloudflared no longer supports connecting legacy tunnels.
+- h2mux tunnel connection protocol is no longer supported. Any tunnels still configured to use this protocol will alert and use http2 tunnel protocol instead. We recommend using quic protocol for all tunnels going forward.
+
+## 2023.2.1
+### Bug fixes
+- Fixed a bug in TCP connection proxy that could result in the connection being closed before all data was written.
+- cloudflared now correctly aborts body write if connection to origin service fails after response headers were sent already.
+- Fixed a bug introduced in the previous release where debug endpoints were removed.
+
+## 2022.12.0
+### Improvements
+- cloudflared now attempts to try other edge addresses before falling back to a lower protoocol.
+- cloudflared tunnel no longer spins up a quick tunnel. The call has to be explicit and provide a --url flag.
+- cloudflared will now randomly pick the first or second region to connect to instead of always connecting to region2 first.
+
 ## 2022.9.0
 ### New Features
 - cloudflared now rejects ingress rules with invalid http status codes for http_status.

-Installation:
+This library requires Go 1.13 or newer; add it to your go.mod with:

-```bash

-### More complex usage

-
-```toml
-# This is a TOML document. Boom.

-name = "Tom Preston-Werner"

-  "omega"
+contacts = [
+    "Donald Duck <donald@duckburg.com>",

 ]
 ```

-And the corresponding Go types are:
+Can be decoded with:

 ```go
-type tomlConfig struct {
-	Title string
-	Owner ownerInfo
-	DB database `toml:"database"`
-	Servers map[string]server
-	Clients clients
+// Create address type which satisfies the encoding.TextUnmarshaler interface.

 }

 }

-type database struct {

+	// &mail.Address{Name:"Donald Duck", Address:"donald@duckburg.com"}
+	// &mail.Address{Name:"Scrooge McDuck", Address:"scrooge@duckburg.com"}
 }
 ```

-Note that a case insensitive match will be tried if an exact match can't be
-found.
+To target TOML specifically you can implement `UnmarshalTOML` TOML interface in
+a similar way.

-A working example of the above can be found in `_examples/example.{go,toml}`.

-Package toml provides facilities for decoding and encoding TOML configuration
-files via reflection. There is also support for delaying decoding with
-the Primitive type, and querying the set of keys in a TOML document with the
-MetaData type.
+Package toml implements decoding and encoding of TOML files.

-The specification implemented: https://github.com/toml-lang/toml
+This package supports TOML v1.0.0, as listed on https://toml.io

-The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
-whether a file is a valid TOML document. It can also be used to print the
-type of each key in a TOML document.
+There is also support for delaying decoding with the Primitive type, and
+querying the set of keys in a TOML document with the MetaData type.

-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.
+The github.com/BurntSushi/toml/cmd/tomlv package implements a TOML validator,
+and can be used to verify if TOML document is valid. It can also be used to
+print the type of each key.

Sudarsan Reddy	99b3736cc7	TUN-6999: cloudflared should attempt other edge addresses before falling back on protocol This PR does two things: It changes how we fallback to a lower protocol: The current state is to try connecting with a protocol. If it fails, fall back to a lower protocol. And try connecting with that and so on. With this PR, if we fail to connect with a protocol, we will try to connect to other edge addresses first. Only if we fail to connect to those will we fall back to a lower protocol. It fixes a behaviour where if we fail to connect to an edge addr, we keep re-trying the same address over and over again. This PR now switches between edge addresses on subsequent connecton attempts. Note that through these switches, it still respects the backoff time. (We are connecting to a different edge, but this helps to not bombard an edge address with connect requests if a particular edge addresses stops working).	2022-12-14 13:17:21 +00:00
João Oliveirinha	e517242194	TUN-6995: Disable quick-tunnels spin up by default Before this change when running cloudflare tunnel command without any subcommand and without any additional flag, we would spin up a QuickTunnel. This is really a strange behaviour because we can easily create unwanted tunnels and results in bad user experience. This also has the side effect on putting more burden in our services that are probably just mistakes. This commit fixes that by requiring user to specify the url command flag. Running cloudflared tunnel alone will result in an error message instead.	2022-12-13 12:03:32 +00:00
Sudarsan Reddy	7dee179652	TUN-7004: Dont show local config dirs for remotely configured tuns cloudflared shows possible directories for config files to be present if it doesn't see one when starting up. For remotely configured files, it may not be necessary to have a config file present. This PR looks to see if a token flag was provided, and if yes, does not log this message.	2022-12-13 11:03:00 +00:00

Sudarsan Reddy	c13b6df0a7	TUN-7003: Tempoarily disable erroneous notarize-app This PR temporarily disables the xcrun notarize-app feature since this is soemthing we've historically had broken. However, what changed now is we set -e for the mac os scripts. We'll need to remove this to unblock mac builds. We could spend time as part of https://jira.cfdata.org/browse/TUN-5789 to look into this.	2022-12-12 13:06:06 +00:00
Sudarsan Reddy	b8b35d99fa	TUN-7002: Randomise first region selection We previously always preferred region2 as the first region to connect to if both the regions cloudflared connects to have the same number of availabe addresses. This change randomises that choice. The first connection, conn index: 0, can now either connect to region 1 or region 2. More importantly, conn 0 and 2 and 1 and 3 need not belong to the same region.	2022-12-07 17:46:15 +00:00

Sudarsan Reddy	45e8eb7275	TUN-6984: [CI] Don't fail on unset. Dont fail on bash unset (set -u) because we initialise to machine defaults if the variables are unset within this script.	2022-12-05 17:50:49 +00:00
Sudarsan Reddy	72503eeaaa	TUN-6984: [CI] Ignore security import errors for code_sigining This PR lets the script skip if the `security import` command exits with a 1. This is okay becuase this script manually checks this exit code to validate if its a duplicate error and if its not, returns.	2022-12-05 16:23:15 +00:00
