## v0.107.15: `POST` Requests Without Bodies

As an additional CSRF protection measure, AdGuard Home now ensures that requests that change its state but have no body do not have a `Content-Type` header set on them.

This concerns the following APIs:

- `POST /control/dhcp/reset_leases`;
- `POST /control/dhcp/reset`;
- `POST /control/parental/disable`;
- `POST /control/parental/enable`;
- `POST /control/querylog_clear`;
- `POST /control/safebrowsing/disable`;
- `POST /control/safebrowsing/enable`;
- `POST /control/safesearch/disable`;
- `POST /control/safesearch/enable`;
- `POST /control/stats_reset`;
- `POST /control/update`.

## v0.107.14: BREAKING API CHANGES

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered.  We have implemented several measures to prevent such vulnerabilities in the future, but some of these measures break backwards compatibility for the sake of better protection.

All JSON APIs that expect a body now check if the request actually has `Content-Type` set to `application/json`.

All new formats for the request and response bodies are documented in `openapi.yaml`.

### `POST /control/filtering/set_rules` And Other Plain-Text APIs

The following APIs, which previously accepted or returned `text/plain` data, now accept or return data as JSON.

#### `POST /control/filtering/set_rules`

Previously, the API accepted a raw list of filters as a plain-text file.  Now, the filters must be presented in a JSON object with the following format:

```json
{
  "rules": [
    "||example.com^",
    "# comment",
    "@@||www.example.com^"
  ]
}
```

#### `GET /control/i18n/current_language` And `POST /control/i18n/change_language`

Previously, these APIs accepted and returned the language code in plain text.  Now, they accept and return them in a JSON object with the following format:

```json
{
  "language": "en"
}
```

#### `POST /control/dhcp/find_active_dhcp`

Previously, the API accepted the name of the network interface as a plain-text string.  Now, it must be contained within a JSON object with the following format:

```json
{
  "interface": "eth0"
}
```

## v0.107.12: API changes

### `GET /control/blocked_services/services`

- The new `GET /control/blocked_services/services` HTTP API allows inspecting all available services.

## v0.107.7: API changes

### The new optional field `"ecs"` in `QueryLogItem`

- The new optional field `"ecs"` in `GET /control/querylog` contains the IP network from an EDNS Client-Subnet option from the request message if any.

### The new possible status code in `/install/configure` response

- The new status code `422 Unprocessable Entity` in the response for `POST /install/configure` which means that the specified password does not meet the strength requirements.

### New possible value of `"name"` field in `QueryLogItemClient`

- The value of `"name"` field in `GET /control/querylog` method is never empty, either persistent client’s name or runtime client’s hostname.

### Lists in `AccessList`

- Fields `"allowed_clients"`, `"disallowed_clients"` and `"blocked_hosts"` in `POST /access/set` now should contain only unique elements.

- Fields `"allowed_clients"` and `"disallowed_clients"` cannot contain the same elements.

### The new field `"private_key_saved"` in `TlsConfig`

- The new field `"private_key_saved"` in `POST /control/tls/configure`, `POST /control/tls/validate` and `GET /control/tls/status` is true if the private key was previously saved as a string and now the private key omitted from communication between server and client due to security issues.

### The new field `"cache_optimistic"` in DNS configuration

- The new optional field `"cache_optimistic"` in `POST /control/dns_config` method makes AdGuard Home use or not use the optimistic cache mechanism.

- The new field `"cache_optimistic"` in `GET /control/dns_info` method is true if AdGuard Home uses the optimistic cache mechanism.

### New possible value of `"interval"` field in `QueryLogConfig`

### The new field `"unicode_name"` in `DNSQuestion`

- The new optional field `"unicode_name"` is the Unicode representation of question’s domain name.  It is only presented if the original question’s domain name is an IDN.

### Documentation fix of `DNSQuestion`

### `POST /control/dhcp/reset_leases`

- The new `POST /control/dhcp/reset_leases` HTTP API allows removing all leases from the DHCP server’s database without erasing its configuration.

### The parameter `"host"` in `GET /apple/*.mobileconfig` is now required

- The parameter `"host"` in `GET` requests for `/apple/doh.mobileconfig` and `/apple/doh.mobileconfig` is now required to prevent unexpected server name’s value.

### The new field `"default_local_ptr_upstreams"` in `GET /control/dns_info`

- The new optional field `"default_local_ptr_upstreams"` is the list of IP addresses AdGuard Home would use by default to resolve PTR request for addresses from locally-served networks.

### The field `"use_private_ptr_resolvers"` in DNS configuration

- The new optional field  `"use_private_ptr_resolvers"` of `"DNSConfig"` specifies if the DNS server should use `"local_ptr_upstreams"` at all.

## v0.106: API changes

### The field `"supported_tags"` in `GET /control/clients`

- Previously undocumented field `"supported_tags"` in the response is now documented.

### New `"private_upstream"` field in `POST /test_upstream_dns`

- The new optional field `"private_upstream"` of `UpstreamConfig` contains the upstream servers for resolving locally-served ip addresses to be checked.

### New fields `"resolve_clients"` and `"local_ptr_upstreams"` in DNS configuration

- The new optional field `"resolve_clients"` of `DNSConfig` is used to turn resolving clients’ addresses on and off.

- The new optional field `"local_ptr_upstreams"` of `"DNSConfig"` contains the upstream servers for resolving addresses from locally-served networks.  The empty `"local_ptr_resolvers"` states that AGH should use resolvers provided by the operating system.

### New `"client_info"` field in `GET /querylog` response

- The new optional field `"client_info"` of `QueryLogItem` objects contains a more full information about the client.

## v0.105: API changes

### New `"client_id"` field in `GET /querylog` response

- The new field `"client_id"` of `QueryLogItem` objects is the ID sent by the client for encrypted requests, if there was any.  See the "[Identifying clients]" section of our wiki.

### New `"dnscrypt"` `"client_proto"` value in `GET /querylog` response

- The field `"client_proto"` can now have the value `"dnscrypt"` when the request was sent over a DNSCrypt connection.

### New `"reason"` in `GET /filtering/check_host` and `GET /querylog`

- The new `RewriteRule` reason is added to `GET /filtering/check_host` and `GET /querylog`.

- Also, the reason which was incorrectly documented as `"ReasonRewrite"` is now correctly documented as `"Rewrite"`, and the previously undocumented `"RewriteEtcHosts"` is now documented as well.

### Multiple matched rules in `GET /filtering/check_host` and `GET /querylog`

- The properties `rule` and `filter_id` are now deprecated.  API users should inspect the newly-added `rules` object array instead.  For most rules, it’s either empty or contains one object, which contains the same things as the old two properties did, but under more correct names:

    ```js
    {
      // …

      // Deprecated.
      "rule": "||example.com^",
      // Deprecated.
      "filter_id": 42,
      // Newly-added.
      "rules": [{
        "text": "||example.com^",
        "filter_list_id": 42
      }]
    }
    ```

  For `$dnsrewrite` rules, they contain all rules that contributed to the result.  For example, if you have the following filtering rules:

    ```adblock
    ||example.com^$dnsrewrite=127.0.0.1
    ||example.com^$dnsrewrite=127.0.0.2
    ```

  The `"rules"` will be something like:

    ```js
    {
      // …

      "rules": [{
        "text": "||example.com^$dnsrewrite=127.0.0.1",
        "filter_list_id": 0
      }, {
        "text": "||example.com^$dnsrewrite=127.0.0.2",
        "filter_list_id": 0
      }]
    }
    ```

  The old fields will be removed in v0.106.0.

  As well as other documentation fixes.

    }
    ```

### API: Set DNS general settings: POST /control/dns_config

- Added `"parallel_requests"`, `"upstream_dns"`, `"bootstrap_dns"` parameters.
- Removed `/control/set_upstreams_config` method.

### A note about web user authentication

If AdGuard Home’s web user is password-protected, a web client must use authentication mechanism when sending requests to server.  Basic access authentication is the most simple method - a client must pass `Authorization` HTTP header along with all requests:

  ```http
  Authorization: Basic BASE64_DATA
  ```

where `BASE64_DATA` is base64-encoded data for `username:password` string.

### Set filtering parameters: POST /control/filtering/config

Replaces the `POST /control/filtering/enable` and `POST /control/filtering/disable` API methods.  Example of a `POST /control/filtering/config` request:

  ```json
  {
    "enabled": true | false,
    "interval": 0 | 1 | 12 | 1*24 | 3*24 | 7*24
  }
  ```

### Set filter parameters: POST /control/filtering/set_url

Replaces the `POST /control/filtering/enable_url` and `POST /control/filtering/disable_url` API methods.

Example of a `POST /control/filtering/set_url` request:

  ```json
  {
    "url": "...",
    "enabled": true | false
  }
  ```

### Set querylog parameters: POST /control/querylog_config

Replaces the `POST /querylog_enable` and `POST /querylog_disable` API methods.

Example of a `POST /control/querylog_config` request:

  {
    "enabled": true | false,
    "interval": 0 | 1 | 12 | 1*24 | 3*24 | 7*24
  }
  ```

### Get statistics data: GET /control/stats

Replaces the `GET /control/stats_top` and `GET /control/stats_history` API methods.  Example of a `200 OK` response:
