 - Added `query` to TermsLookup to support terms lookup by query
 - Added `mapper_type` and `mapper_settings` to `IngestionSource` index settings ([#1155](https://github.com/opensearch-project/opensearch-api-specification/pull/1155))
 - Added `search` and `warm` node roles to `NodeRole`, and modeled the pre-3.0 `search` role (renamed to `warm` in 3.0) as a version-scoped branch ([#1006](https://github.com/opensearch-project/opensearch-api-specification/pull/1006))
+- Added `false_allow_templates` to `DynamicMapping` ([#1178](https://github.com/opensearch-project/opensearch-api-specification/pull/1178))
 
 ### Deprecated
 - Marked the plural `_aliases` URL forms of `put_alias` and `delete_alias` as deprecated; the singular `_alias` form is the canonical path ([#1131](https://github.com/opensearch-project/opensearch-api-specification/pull/1131))
