Release 2023.6.1

to pass multiple values here.

The idea of this PR is simply to add a configurable unregister UDP
timeout.

-  * 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.

+# CORS net/http middleware
+
+[go-chi/cors](https://github.com/go-chi/cors) is a fork of [github.com/rs/cors](https://github.com/rs/cors) that
+provides a `net/http` compatible middleware for performing preflight CORS checks on the server side. These headers
+are required for using the browser native [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API).
+
+This middleware is designed to be used as a top-level middleware on the [chi](https://github.com/go-chi/chi) router.
+Applying with within a `r.Group()` or using `With()` will not work without routes matching `OPTIONS` added.
+
+## Usage
+
+```go
+func main() {
+  r := chi.NewRouter()
+
+  // Basic CORS
+  // for more ideas, see: https://developer.github.com/v3/#cross-origin-resource-sharing
+  r.Use(cors.Handler(cors.Options{
+    // AllowedOrigins:   []string{"https://foo.com"}, // Use this to allow specific origin hosts
+    AllowedOrigins:   []string{"https://*", "http://*"},
+    // AllowOriginFunc:  func(r *http.Request, origin string) bool { return true },
+    AllowedMethods:   []string{"GET", "POST", "PUT", "DELETE", "OPTIONS"},
+    AllowedHeaders:   []string{"Accept", "Authorization", "Content-Type", "X-CSRF-Token"},
+    ExposedHeaders:   []string{"Link"},
+    AllowCredentials: false,
+    MaxAge:           300, // Maximum value not ignored by any of major browsers
+  }))
+
+  r.Get("/", func(w http.ResponseWriter, r *http.Request) {
+    w.Write([]byte("welcome"))
+  })
+
+  http.ListenAndServe(":3000", r)
+}
+```

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+Package jose aims to provide an implementation of the Javascript Object Signing
+and Encryption set of standards. This includes support for JSON Web Encryption,
+JSON Web Signature, and JSON Web Token standards.
+
+**Disclaimer**: This library contains encryption software that is subject to
+the U.S. Export Administration Regulations. You may not export, re-export,
+transfer or download this code or any part of it in violation of any United
+States law, directive or regulation. In particular this software may not be
+exported or re-exported in any form or on any media to Iran, North Sudan,
+Syria, Cuba, or North Korea, or to denied persons or entities mentioned on any
+US maintained blocked list.
+
+## Overview
+
+The implementation follows the
+[JSON Web Encryption](http://dx.doi.org/10.17487/RFC7516) (RFC 7516),
+[JSON Web Signature](http://dx.doi.org/10.17487/RFC7515) (RFC 7515), and
+[JSON Web Token](http://dx.doi.org/10.17487/RFC7519) (RFC 7519) specifications.
+Tables of supported algorithms are shown below. The library supports both
+the compact and JWS/JWE JSON Serialization formats, and has optional support for
+multiple recipients. It also comes with a small command-line utility
+([`jose-util`](https://github.com/go-jose/go-jose/tree/master/jose-util))
+for dealing with JOSE messages in a shell.
+
+**Note**: We use a forked version of the `encoding/json` package from the Go
+standard library which uses case-sensitive matching for member names (instead
+of [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html)).
+This is to avoid differences in interpretation of messages between go-jose and
+libraries in other languages.
+
+### Versions
+
+[Version 2](https://gopkg.in/go-jose/go-jose.v2)
+([branch](https://github.com/go-jose/go-jose/tree/v2),
+[doc](https://godoc.org/gopkg.in/go-jose/go-jose.v2)) is the current stable version:
+
+    import "gopkg.in/go-jose/go-jose.v2"
+
+[Version 3](https://github.com/go-jose/go-jose)
+([branch](https://github.com/go-jose/go-jose/tree/master),
+[doc](https://godoc.org/github.com/go-jose/go-jose)) is the under development/unstable version (not released yet):
+
+    import "github.com/go-jose/go-jose/v3"
+
+All new feature development takes place on the `master` branch, which we are
+preparing to release as version 3 soon. Version 2 will continue to receive
+critical bug and security fixes. Note that starting with version 3 we are
+using Go modules for versioning instead of `gopkg.in` as before. Version 3 also will require Go version 1.13 or higher.
+
+Version 1 (on the `v1` branch) is frozen and not supported anymore.
+
+### Supported algorithms
+
+See below for a table of supported algorithms. Algorithm identifiers match
+the names in the [JSON Web Algorithms](http://dx.doi.org/10.17487/RFC7518)
+standard where possible. The Godoc reference has a list of constants.

+### Supported key types
+
+See below for a table of supported key types. These are understood by the
+library, and can be passed to corresponding functions such as `NewEncrypter` or
+`NewSigner`. Each of these keys can also be wrapped in a JWK if desired, which
+allows attaching a key id.
+

+Examples can be found in the Godoc
+reference for this package. The
+[`jose-util`](https://github.com/go-jose/go-jose/tree/master/jose-util)
+subdirectory also contains a small command-line utility which might be useful
+as an example as well.

+# Safe JSON
+
+This repository contains a fork of the `encoding/json` package from Go 1.6.
+
+The following changes were made:
+
+* Object deserialization uses case-sensitive member name matching instead of
+  [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html).
+  This is to avoid differences in the interpretation of JOSE messages between
+  go-jose and libraries written in other languages.
+* When deserializing a JSON object, we check for duplicate keys and reject the
+  input whenever we detect a duplicate. Rather than trying to work with malformed
+  data, we prefer to reject it right away.
