+* [Issue 8589](https://bugs.chromium.org/p/gerrit/issues/detail?id=8589):
+Remove approval requirement search from basic search documentation.
+
+  Using approval requirements in basic search, for example `Code-Review=2`
+  without the explicit `label:` predicate can never work as expected because
+  the query is also considered as a comment search, which matches on all
+  changes that have received a vote on that label, regardless of the label
+  score.
+
+  The section about approval requirements is removed from the basic search
+  documentation to avoid confusion. It is also now recommended to use explicit
+  query predicates when predictable results are desired.
+
+* [Issue 8597](https://bugs.chromium.org/p/gerrit/issues/detail?id=8597):
+Clarify the behavior of `ownerin:` and `reviwerin:` queries.
+
+  When the ownerin: or reviewerin: predicate is used in a query without any
+  additional explicit index predicate, it will default to only include changes
+  in status 'OPEN'.
+
 * Fix internal server error when using the `query:` search with a non-existing
 named query.
