+## Unreleased [minor]
+
+> Development of this release was supported by the [French Ministry for Foreign Affairs](https://www.diplomatie.gouv.fr/fr/politique-etrangere-de-la-france/diplomatie-numerique/) through its ministerial [State Startups incubator](https://beta.gouv.fr/startups/open-terms-archive.html) under the aegis of the Ambassador for Digital Affairs.
+
+### Added
+
+- Add support for parameterized filters in service declarations using object syntax; to pass parameters to curstom filters (with following signature: `customFilter(document, params, context)`), use the following syntax:
+
+  ```json
+  "filter": [
+    {
+      "customFilter": "parameter"
+    },
+    {
+      "customFilter2": ["parameter1", "parameter2"]
+    }
+  ]
+  ```
+
+- Add `removeQueryParams` built-in filter to remove specified query parameters from URLs in links and images; to use it in service declarations, add the following to your `filter` array:
+  
+  ```json
+  "filter": [
+    {
+      "removeQueryParams": ["paramToRemove1", "paramToRemove2"]
+    }
+  ]
+  ```
