# AdGuard Home API Change Log

<!-- TODO(a.garipov): Reformat in accordance with the KeepAChangelog spec. -->

## v0.108.0: API changes



## v0.107.17: API Changes

### `GET /control/blocked_services/services` is deprecated

Use `GET /control/blocked_services/all`.

### `GET /control/blocked_services/all`

* The new `GET /control/blocked_services/all` HTTP API allows inspecting all
  available services and their data, such as SVG icons and human-readable names.



## 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.



## v0.107.3: API changes

### The new field `"version"` in `AddressesInfo`

* The new field `"version"` in `GET /install/get_addresses` is the version of
  the AdGuard Home instance.



## v0.107.0: API changes

### The new field `"cached"` in `QueryLogItem`

* The new field `"cached"` in `GET /control/querylog` is true if the response is
  served from cache instead of being resolved by an upstream server.

### New constant values for `filter_list_id` field in `ResultRule`

* Value of `0` is now used for custom filtering rules list.

* Value of `-1` is now used for rules generated from the operating system hosts
  files.

* Value of `-2` is now used for blocked services' rules.

* Value of `-3` is now used for rules generated by parental control web service.

* Value of `-4` is now used for rules generated by safe browsing web service.

* Value of `-5` is now used for rules generated by safe search web service.

### 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 value of `"interval"` field in `POST /control/querylog_config` and `GET
  /control/querylog_info` methods could now take the value of `0.25`.  It's
  equal to 6 hours.

* All the possible values of `"interval"` field are enumerated.

* The type of `"interval"` field is now `number` instead of `integer`.

### ClientIDs in Access Settings

* The `POST /control/access/set` HTTP API now accepts ClientIDs in
  `"allowed_clients"` and `"disallowed_clients"` fields.

### 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`

* Previously incorrectly named field `"host"` in `DNSQuestion` is now named
  `"name"`.

###  Disabling Statistics

* The `POST /control/stats_config` HTTP API allows disabling statistics by
  setting `"interval"` to `0`.

### `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.

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

* Objects in the `"auto_clients"` array now have the `"whois_info"` field.

### New response code in `POST /control/login`

* `429` is returned when user is out of login attempts.  It adds the
  `Retry-After` header with the number of seconds of block left in it.

### 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:

  ```
  ||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.
