+# Changelog
+
+## 0.1.0 (2019-11-19)
+
+
+### ⚠ BREAKING CHANGES
+
+* The `areTimestampsInSnapshotsEnabled()` setting is now enabled
+by default so timestamp fields read from a `DocumentSnapshot` will be returned
+as `Timestamp` objects instead of `Date`. Any code expecting to receive a
+`Date` object must be updated.
+
+### Features
+
+* **firestore:** add support for IN & ARRAY_CONTAINS_ANY query field filters ([#5803](https://www.github.com/googleapis/java-firestore/issues/5803)) ([76a7e46](https://www.github.com/googleapis/java-firestore/commit/76a7e466c837f2d9dfde9be01c0b78668b393494)), closes [/github.com/googleapis/googleapis/blob/10f91fa12f70e8e0209a45fc10807ed1f77c7e4e/google/firestore/v1/query.proto#L106-L112](https://www.github.com/googleapis//github.com/googleapis/googleapis/blob/10f91fa12f70e8e0209a45fc10807ed1f77c7e4e/google/firestore/v1/query.proto/issues/L106-L112)
+
+
+### Firestore
+
+* change timestampsInSnapshots default to true. ([#4353](https://www.github.com/googleapis/java-firestore/issues/4353)) ([66539a8](https://www.github.com/googleapis/java-firestore/commit/66539a85f8f9c8e476b2b99e9335309ae86a8cdc))
