 This article contains the changelog for [AdGuard DNS API](private-dns/api/overview.md).
 
+## v1.6
+
+- Added new section "Access settings" for DNS profiles (`access_settings`). By customizing these fields, you’ll be able to protect your AdGuard DNS server from unauthorized access:
+
+    - `allowed_clients` — here you can specify which clients can use your DNS server. This field will have priority over the `blocked_clients` field
+    - `blocked_clients` — here you can specify which clients are not allowed to use your DNS server
+    - `blocked_domain_rules` — here you can specify which domains are not allowed to access your DNS server, as well as define such domains with wildcard and DNS filtering rules
+
+- Added new limits to Account limits:
+
+    - `access_rules` provides the sum of currently used `blocked_clients` and `blocked_domain_rules` values, as well as the limit on access rules
+    - `user_rules` shows the amount of created user rules, as well as the limit on them
+
+- Added new setting: `ip_log_enabled` for the ability to log client IP addresses and domains.
+
+- Added new error code `FIELD_REACHED_LIMIT` to indicate when limits have been reached:
+
+    - For the total number of `blocked_clients` and `blocked_domain_rules` in access settings
+    - For `rules` in custom user rules settings
+
 ## v1.5
 
 - Added new setting `block_nrd` and group all security-related settings to one place.
