+  title: Query phase KNN now supports query_vector_builder
+  body: |-
+    It is now possible to pass `model_text` and `model_id` within a `knn` query
+    in the query DSL to convert a text query into a dense vector and run the
+    nearest neighbor query on it, instead of requiring the dense vector to be
+    directly passed (within the `query_vector` parameter). Similar to the
+    top-level `knn` query (executed in the DFS phase), it is possible to supply
+    a `query_vector_builder` object containing a `text_embedding` object with
+    `model_text` (the text query to be converted into a dense vector) and
+    `model_id` (the identifier of a deployed model responsible for transforming
+    the text query into a dense vector).
