# AdGuard Home API Change Log

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

## v0.107: 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`.

### Client IDs in Access Settings

* The `POST /control/access/set` HTTP API now accepts client IDs 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.

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:

	Authorization: Basic BASE64_DATA

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

	}

Response:

	200 OK


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

Replaces these API methods:

	POST /control/filtering/enable_url

	{
		"url": "..."
		"enabled": true | false
	}

Response:
