@@ -6,6 +6,8 @@
 
 - Removed constructor from `SynonymMap` with `IEnumerable<string>` parameter.
 - `SearchServiceClient.GetIndexes` and `SearchServiceClient.GetIndexesAsync` now return `Pageable<SearchIndex>` and `AsyncPageable<SearchIndex>` respectively.
+- Replaced `MatchConditions` parameters with `bool onlyIfUnchanged` parameters that require a model with an `ETag` property.
+- `ETag` properties have been redefined from `string` to `Azure.ETag?` consistent with other packages.
