 ### Added
 
-- The new HTTP API, `GET /control/querylog/export`, which can be used to
-  export query log items.  See `openapi/openapi.yaml` for the full description
-  ([#3389]).
-- The ability to set inactivity periods for filtering blocked services in the
-  configuration file ([#951]).  The UI changes are coming in the upcoming
-  releases.
-- The ability to edit rewrite rules via `PUT /control/rewrite/update` HTTP API
-  ([#1577]).
-
-### Changed
-
-#### Configuration Changes
-
-In this release, the schema version has changed from 20 to 21.
-
-- Property `dns.blocked_services`, which in schema versions 20 and earlier used
-  to be a list containing ids of blocked services, is now an object containing
-  ids and schedule for blocked services:
-
-  ```yaml
-  # BEFORE:
-  'blocked_services':
-  - id_1
-  - id_2
-
-  # AFTER:
-  'blocked_services':
-    'ids':
-    - id_1
-    - id_2
-    'schedule':
-      'time_zone': 'Local'
-      'sun':
-        'start': '0s'
-        'end': '24h'
-      'mon':
-        'start': '10m'
-        'end': '23h30m'
-      'tue':
-        'start': '20m'
-        'end': '23h'
-      'wed':

-      'sat':
-        'start': '1h'
-        'end': '21h'
-  ```
-
-  To rollback this change, replace `dns.blocked_services` object with the list
-  of ids of blocked services and change the `schema_version` back to `20`.
-
-### Fixed
-
-- Queries with the question-section target `.`, for example `NS .`, are now
-  counted in the statistics and correctly shown in the query log ([#5910]).
-- Safe Search not working with `AAAA` queries for domains that don't have `AAAA`
-  records ([#5913]).
