Release 2023.7.3

Will no longer provide full hostname with path from provided
`--hostname` flag for cloudflared access to the Host header field.
This addresses certain issues caught from a security fix in go
1.19.11 and 1.20.6 in the net/http URL parsing.

+## 2023.7.0
+### New Features
+- You can now enable additional diagnostics over the management.argotunnel.com service for your active cloudflared connectors via a new runtime flag `--management-diagnostics` (or env `TUNNEL_MANAGEMENT_DIAGNOSTICS`). This feature is provided as opt-in and requires the flag to enable. Endpoints such as /metrics provides your prometheus metrics endpoint another mechanism to be reached. Additionally /debug/pprof/(goroutine|heap) are also introduced to allow for remotely retrieving active pprof information from a running cloudflared connector.
+
 ## 2023.4.1
 ### New Features
 - You can now stream your logs from your remote cloudflared to your local terminal with `cloudflared tail <TUNNEL-ID>`. This new feature requires the remote cloudflared to be version 2023.4.1 or higher.

-(b) You may distribute such Executable Form under the terms of this
-    License, or sublicense it under different terms, provided that the
-    license for the Executable Form does not attempt to limit or alter
-    the recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-You may create and distribute a Larger Work under terms of Your choice,
-provided that You also comply with the requirements of this License for
-the Covered Software. If the Larger Work is a combination of Covered
-Software with a work governed by one or more Secondary Licenses, and the
-Covered Software is not Incompatible With Secondary Licenses, this
-License permits You to additionally distribute such Covered Software
-under the terms of such Secondary License(s), so that the recipient of
-the Larger Work may, at their option, further distribute the Covered
-Software under the terms of either this License or such Secondary
-License(s).
-
-3.4. Notices
-
-You may not remove or alter the substance of any license notices
-(including copyright notices, patent notices, disclaimers of warranty,
-or limitations of liability) contained within the Source Code Form of
-the Covered Software, except that You may alter any license notices to
-the extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-You may choose to offer, and to charge a fee for, warranty, support,
-indemnity or liability obligations to one or more recipients of Covered
-Software. However, You may do so only on Your own behalf, and not on
-behalf of any Contributor. You must make it absolutely clear that any
-such warranty, support, indemnity, or liability obligation is offered by
-You alone, and You hereby agree to indemnify every Contributor for any
-liability incurred by such Contributor as a result of warranty, support,
-indemnity or liability terms You offer. You may include additional
-disclaimers of warranty and limitations of liability specific to any
-jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
----------------------------------------------------
-
-If it is impossible for You to comply with any of the terms of this
-License with respect to some or all of the Covered Software due to
-statute, judicial order, or regulation then You must: (a) comply with
-the terms of this License to the maximum extent possible; and (b)
-describe the limitations and the code they affect. Such description must
-be placed in a text file included with all distributions of the Covered
-Software under this License. Except to the extent prohibited by statute
-or regulation, such description must be sufficiently detailed for a
-recipient of ordinary skill to be able to understand it.
-
-5. Termination
---------------
-
-5.1. The rights granted under this License will terminate automatically
-if You fail to comply with any of its terms. However, if You become
-compliant, then the rights granted under this License from a particular
-Contributor are reinstated (a) provisionally, unless and until such
-Contributor explicitly and finally terminates Your grants, and (b) on an
-ongoing basis, if such Contributor fails to notify You of the
-non-compliance by some reasonable means prior to 60 days after You have
-come back into compliance. Moreover, Your grants from a particular
-Contributor are reinstated on an ongoing basis if such Contributor
-notifies You of the non-compliance by some reasonable means, this is the
-first time You have received notice of non-compliance with this License
-from such Contributor, and You become compliant prior to 30 days after
-Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-infringement claim (excluding declaratory judgment actions,
-counter-claims, and cross-claims) alleging that a Contributor Version
-directly or indirectly infringes any patent, then the rights granted to
-You by any and all Contributors for the Covered Software under Section
-2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all
-end user license agreements (excluding distributors and resellers) which
-have been validly granted by You or Your distributors under this License
-prior to termination shall survive termination.

-# GoCertifi: SSL Certificates for Golang
-
-This Go package contains a CA bundle that you can reference in your Go code.
-This is useful for systems that do not have CA bundles that Golang can find
-itself, or where a uniform set of CAs is valuable.
-
-This is the same CA bundle that ships with the
-[Python Requests](https://github.com/kennethreitz/requests) library, and is a
-Golang specific port of [certifi](https://github.com/kennethreitz/certifi). The
-CA bundle is derived from Mozilla's canonical set.
-
-## Usage
-
-You can use the `gocertifi` package as follows:
-
-```go
-import "github.com/certifi/gocertifi"
-
-certPool, err := gocertifi.CACerts()
-```
-
-You can use the returned `*x509.CertPool` as part of an HTTP transport, for example:
-
-```go
-import (
-	"net/http"
-	"crypto/tls"
-)
-
-// Setup an HTTP client with a custom transport
-transport := &http.Transport{
-	Proxy: ProxyFromEnvironment,
-	DialContext: (&net.Dialer{
-		Timeout:   30 * time.Second,
-		KeepAlive: 30 * time.Second,
-		DualStack: true,
-	}).DialContext,
-	ForceAttemptHTTP2:     true,
-	MaxIdleConns:          100,
-	IdleConnTimeout:       90 * time.Second,
-	TLSHandshakeTimeout:   10 * time.Second,
-	ExpectContinueTimeout: 1 * time.Second,
-}
-// or, starting with go1.13 simply use:
-// transport := http.DefaultTransport.(*http.Transport).Clone()
-
-transport.TLSClientConfig = &tls.Config{RootCAs: certPool}
-client := &http.Client{Transport: transport}
-
-// Make an HTTP request using our custom transport
-resp, err := client.Get("https://example.com")
-```
-
-## Detailed Documentation
-
-Import as follows:
-
-```go
-import "github.com/certifi/gocertifi"
-```
-
-### Functions
-
-```go
-func CACerts() (*x509.CertPool, error)
-```
-CACerts builds an X.509 certificate pool containing the Mozilla CA Certificate
-bundle. This can't actually error and always returns successfully with `nil`
-as the error. This will be replaced in `v2` to only return the `CertPool`.

-# genny - Generics for Go
-
-[![Build Status](https://travis-ci.org/cheekybits/genny.svg?branch=master)](https://travis-ci.org/cheekybits/genny) [![GoDoc](https://godoc.org/github.com/cheekybits/genny/parse?status.png)](http://godoc.org/github.com/cheekybits/genny/parse)

-```
-
-=====
-
-(pron. Jenny) by Mat Ryer ([@matryer](https://twitter.com/matryer)) and Tyler Bunnell ([@TylerJBunnell](https://twitter.com/TylerJBunnell)).
-
-Until the Go core team include support for [generics in Go](http://golang.org/doc/faq#generics), `genny` is a code-generation generics solution. It allows you write normal buildable and testable Go code which, when processed by the `genny gen` tool, will replace the generics with specific types.
-
-  * Generic code is valid Go code
-  * Generic code compiles and can be tested
-  * Use `stdin` and `stdout` or specify in and out files
-  * Supports Go 1.4's [go generate](http://tip.golang.org/doc/go1.4#gogenerate)
-  * Multiple specific types will generate every permutation
-  * Use `BUILTINS` and `NUMBERS` wildtype to generate specific code for all built-in (and number) Go types
-  * Function names and comments also get updated
-
-## Library
-
-We have started building a [library of common things](https://github.com/cheekybits/gennylib), and you can use `genny get` to generate the specific versions you need.
-
-For example: `genny get maps/concurrentmap.go "KeyType=BUILTINS ValueType=BUILTINS"` will print out generated code for all types for a concurrent map. Any file in the library may be generated locally in this way using all the same options given to `genny gen`.
-
-## Usage
-
-```
-genny [{flags}] gen "{types}"
-
-gen - generates type specific code from generic code.
-get <package/file> - fetch a generic template from the online library and gen it.
-
-{flags}  - (optional) Command line flags (see below)
-{types}  - (required) Specific types for each generic type in the source
-{types} format:  {generic}={specific}[,another][ {generic2}={specific2}]
-
-Examples:
-  Generic=Specific
-  Generic1=Specific1 Generic2=Specific2
-  Generic1=Specific1,Specific2 Generic2=Specific3,Specific4
-
-Flags:
-  -in="": file to parse instead of stdin
-  -out="": file to save output to instead of stdout
-  -pkg="": package name for generated files
-```
-
-  * Comma separated type lists will generate code for each type
-
-### Flags
-
-  * `-in` - specify the input file (rather than using stdin)
-  * `-out` - specify the output file (rather than using stdout)
-
-### go generate
-
-To use Go 1.4's `go generate` capability, insert the following comment in your source code file:
-
-```
-//go:generate genny -in=$GOFILE -out=gen-$GOFILE gen "KeyType=string,int ValueType=string,int"
-```
-
-  * Start the line with `//go:generate `
-  * Use the `-in` and `-out` flags to specify the files to work on
-  * Use the `genny` command as usual after the flags
-
-Now, running `go generate` (in a shell) for the package will cause the generic versions of the files to be generated.
-
-  * The output file will be overwritten, so it's safe to call `go generate` many times
-  * Use `$GOFILE` to refer to the current file
-  * The `//go:generate` line will be removed from the output
-
-To see a real example of how to use `genny` with `go generate`, look in the [example/go-generate directory](https://github.com/cheekybits/genny/tree/master/examples/go-generate).
-
-## How it works
-
-Define your generic types using the special `generic.Type` placeholder type:
-
-```go
-type KeyType generic.Type
-type ValueType generic.Type
-```
-
-  * You can use as many as you like
-  * Give them meaningful names
-
-Then write the generic code referencing the types as your normally would:
-
-```go
-func SetValueTypeForKeyType(key KeyType, value ValueType) { /* ... */ }
-```
-
-  * Generic type names will also be replaced in comments and function names (see Real example below)
-
-Since `generic.Type` is a real Go type, your code will compile, and you can even write unit tests against your generic code.
-
-#### Generating specific versions
-
-Pass the file through the `genny gen` tool with the specific types as the argument:
-
-```
-cat generic.go | genny gen "KeyType=string ValueType=interface{}"
-```
-
-The output will be the complete Go source file with the generic types replaced with the types specified in the arguments.
-
-## Real example
-
-Given [this generic Go code](https://github.com/cheekybits/genny/tree/master/examples/queue) which compiles and is tested:
-
-```go
-package queue
-
-import "github.com/cheekybits/genny/generic"
-
-// NOTE: this is how easy it is to define a generic type
-type Something generic.Type
-
-// SomethingQueue is a queue of Somethings.
-type SomethingQueue struct {
-  items []Something
-}
-
-func NewSomethingQueue() *SomethingQueue {
-  return &SomethingQueue{items: make([]Something, 0)}
-}
-func (q *SomethingQueue) Push(item Something) {
-  q.items = append(q.items, item)
-}
-func (q *SomethingQueue) Pop() Something {
-  item := q.items[0]
-  q.items = q.items[1:]
-  return item
-}
-```
-
-When `genny gen` is invoked like this:
-
-```
-cat source.go | genny gen "Something=string"
-```
-
-It outputs:
-
-```go
-// This file was automatically generated by genny.
-// Any changes will be lost if this file is regenerated.
-// see https://github.com/cheekybits/genny
-
-package queue
-
-// StringQueue is a queue of Strings.
-type StringQueue struct {
-  items []string
-}
-
-func NewStringQueue() *StringQueue {
-  return &StringQueue{items: make([]string, 0)}
-}
-func (q *StringQueue) Push(item string) {
-  q.items = append(q.items, item)
-}
-func (q *StringQueue) Pop() string {
-  item := q.items[0]
-  q.items = q.items[1:]
-  return item
-}
-```
-
-To get a _something_ for every built-in Go type plus one of your own types, you could run:
-
-```
-cat source.go | genny gen "Something=BUILTINS,*MyType"
-```
-
-#### More examples
-
-Check out the [test code files](https://github.com/cheekybits/genny/tree/master/parse/test) for more real examples.
-
-## Writing test code
-
-Once you have defined a generic type with some code worth testing:
-
-```go
-package slice
-
-import (
-  "log"
-  "reflect"
-
-  "github.com/stretchr/gogen/generic"
-)
-
-type MyType generic.Type
-
-func EnsureMyTypeSlice(objectOrSlice interface{}) []MyType {
-  log.Printf("%v", reflect.TypeOf(objectOrSlice))
-  switch obj := objectOrSlice.(type) {
-  case []MyType:
-    log.Println("  returning it untouched")
-    return obj
-  case MyType:
-    log.Println("  wrapping in slice")
-    return []MyType{obj}
-  default:
-    panic("ensure slice needs MyType or []MyType")
-  }
-}
-```
-
-You can treat it like any normal Go type in your test code:
-
-```go
-func TestEnsureMyTypeSlice(t *testing.T) {
-
-  myType := new(MyType)
-  slice := EnsureMyTypeSlice(myType)
-  if assert.NotNil(t, slice) {
-    assert.Equal(t, slice[0], myType)
-  }
-
-  slice = EnsureMyTypeSlice(slice)
-  log.Printf("%#v", slice[0])
-  if assert.NotNil(t, slice) {
-    assert.Equal(t, slice[0], myType)
-  }
-
-}
-```
-
-### Understanding what `generic.Type` is
-
-Because `generic.Type` is an empty interface type (literally `interface{}`) every other type will be considered to be a `generic.Type` if you are switching on the type of an object. Of course, once the specific versions are generated, this issue goes away but it's worth knowing when you are writing your tests against generic code.
