In some special use cases (probably not very common), you might want to **restrict** the cookies that you want to receive.

Your API now has the power to control its own <abbr title="This is a joke, just in case. It has nothing to do with cookie consents, but it's funny that even the API can now reject the poor cookies. Have a cookie. 🍪">cookie consent</abbr>. 🤪🍪

You can use Pydantic's model configuration to `forbid` any `extra` fields:

                        {
                            "type": "org.gradle.api.AntBuilder",
                            "member": "Class org.gradle.api.AntBuilder",
                            "acceptation": "org.gradle.api.AntBuilder now extends groovy.ant.AntBuilder",
                            "changes": [
                                "Abstract method has been added in implemented interface"
                            ]
                        },

package gorm

import (
	"database/sql"
	"database/sql/driver"
	"encoding/json"
	"reflect"

	"github.com/jinzhu/now"
	"gorm.io/gorm/clause"
	"gorm.io/gorm/schema"
)

type DeletedAt sql.NullTime

// Scan implements the Scanner interface.
func (n *DeletedAt) Scan(value interface{}) error {
	return (*sql.NullTime)(n).Scan(value)
}

// Value implements the driver Valuer interface.

```

You will also need to configure this dependency:

```
dependencies {
  implementation "org.bouncycastle:bcprov-jdk15on:1.65"
}
```

 *  Upgrade: [Kotlin 1.4.10][kotlin_1_4_10]. We now use Kotlin 1.4.x [functional
    interfaces][fun_interface] for `Authenticator`, `Interceptor`, and others.
 *  Upgrade: Build with Conscrypt 2.5.1.

But first, let's check some small concepts.

## In a hurry?

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.

## OAuth2

OAuth2 is a specification that defines several ways to handle authentication and authorization.

It is quite an extensive specification and covers several complex use cases.

// - freeze (freezes all incoming S3 API calls)
// - unfreeze (unfreezes previously frozen S3 API calls)
//
// This newer API now returns back status per remote peer and local regarding
// if a "restart/stop" was successful or not. Service signal now supports
// a dry-run that helps skip the nodes that may have hung drives. By default
// restart/stop will ignore the servers that are hung on drives. You can use
