[#19692]: https://github.com/apache/datafusion/issues/19692
+### `PlannerContext` outer query schema API now uses a stack
+
+`PlannerContext` no longer stores a single `outer_query_schema`. It now tracks
a
+stack of outer relation schemas so nested subqueries can access non-adjacent
+outer relations.
+
+**Before:**
+
+```rust,ignore
+let old_outer_query_schema =
+ planner_context.set_outer_query_schema(Some(input_schema.clone().into()));
+let sub_plan = self.query_to_plan(subquery, planner_context)?;
+planner_context.set_outer_query_schema(old_outer_query_schema);
+```
+
+**After:**
+
+```rust,ignore
+planner_context.append_outer_query_schema(input_schema.clone().into());
+let sub_plan = self.query_to_plan(subquery, planner_context)?;
+planner_context.pop_outer_query_schema();
+```
+
### `FileSinkConfig` adds `file_output_mode`
`FileSinkConfig` now includes a `file_output_mode: FileOutputMode` field to
control
