+### Changes to search promotions contrib module
+
+#### Deprecated `search_garbage_collect` management command has been removed
+
+In 5.0 the documentation advised that the `search_garbage_collect` command used to remove old stored search queries and daily hits has been moved to [`searchpromotions_garbage_collect`](searchpromotions_garbage_collect).
+
+The old command has now been fully removed and if called will throw an error.
+
+#### Changes to URL names and templates
+
+Some search promotions URLs and templates have now moved from the main admin search module into the search promotions module.
