 # Changelog
 
-### [1.35.2](https://www.github.com/googleapis/java-firestore/compare/v1.35.1...v1.35.2) (2020-07-16)
+## [2.0.0](https://www.github.com/googleapis/java-firestore/compare/v1.35.2...v2.0.0) (2020-08-14)
+
+
+### New Features
+
+#### Query Partition API
+
+New API and backend RPC which allows for fetching a set of cursor keys for a 
+Collection Group Query. Accessible via the new [`CollectionGroup#getPartitions(long,ApiStreamObserver)`](https://googleapis.dev/java/google-cloud-firestore/2.0.0/com/google/cloud/firestore/CollectionGroup.html#getPartitions-long-com.google.api.gax.rpc.ApiStreamObserver-) method. 
+
+#### Read-Only Transaction Options
+
+[`TransactionOptions`](https://googleapis.dev/java/google-cloud-firestore/2.0.0/com/google/cloud/firestore/TransactionOptions.html)
+has been refactored to provide the ability to configure options for read-only 
+transactions along with the existing configuration for read-write transactions.
+
+This new ability is provided via the new [`TransactionOptions.createReadOnlyOptionsBuilder()`](https://googleapis.dev/java/google-cloud-firestore/2.0.0/com/google/cloud/firestore/TransactionOptions.html#createReadOnlyOptionsBuilder--) 
+type safe builder.
+
+Along with the new type safe builder for read-only options, there is a new type 
+safe builder for read-write options as well accessible via [`TransactionOptions.createReadWriteOptionsBuilder()`](https://googleapis.dev/java/google-cloud-firestore/2.0.0/com/google/cloud/firestore/TransactionOptions.html#createReadWriteOptionsBuilder--). Each of the existing `TransactionOptions.create(...)`
+methods for configuring read-write options has been deprecated in favor of the new builder.
+
+#### EmulatorCredentials
+
+`com.google.cloud.firestore.FirestoreOptions.Builder.FakeCredentials` has been
+made static and renamed to `com.google.cloud.firestore.FirestoreOptions.EmulatorCredentials`
+allowing instantiation outside `FirestoreOptions.Builder`.
+
+When connecting to the Cloud Firestore Emulator via `FirestoreOptions` rather than
+the environment variable `FIRESTORE_EMULATOR_HOST`, a custom credential implementation
+must be specified to allow various admin operations in the emulator. Previously
+this required users to create their own implementation due to it not being 
+possible to construct a `FakeCredential`. As part of this change, `EmulatorCredentials`
+is static and therefore able to be constructed from any location.
+
+### Breaking Changes
+
+#### New Firestore Admin Client API Artifact
+
+The Cloud Firestore Admin Client has been migrated to its own maven artifact `com.google.cloud:google-cloud-firestore-admin`
+rather than being bundled in `com.google.cloud:google-cloud-firestore`. All 
+packages and classes have retained their existing names.
+
+The new artifact is included in the `com.google.cloud:google-cloud-firestore-bom`, 
+`com.google.cloud:google-cloud-bom` and `com.google.cloud:libraries-bom` 
+artifacts and is accessible by adding the new dependency to your `pom.xml` file:
+
+```xml
+<dependency>
+  <groupId>com.google.cloud</groupId>
+  <artifactId>google-cloud-firestore-admin</artifactId>
+</dependency>
+```
+
+#### Removal of v1beta1
+
+Cloud Firestore has been GA for some time now, and the `google-cloud-firestore` 
+code base has been using the protos and generated classes for the v1 api since 
+that time. As such, we will no longer be publishing artifacts for the deprecated
+v1beta1 protos. All functionality from v1beta1 is present in v1, and all users
+should update any code to use v1.
+
+#### Removal of support for `java.util.Date` in Snapshots
+
+It is no longer possible to configure the ability for `java.util.Date` to be
+returned from `DocumentSnapshot.get(FieldPath)` or `DocumentSnapshot.getData()`
+for properties which are stored as Timestamps in Cloud Firestore.
+
+The default behavior has been to return `com.google.cloud.Timestamp` by default
+for some time, and is now the only option. Any code that is dependent on the old
+behavior must be updated to use Timestamps instead of Date.
+
+### Laundry List of Pull Requests
+
+#### ⚠ BREAKING CHANGES
+
+* add support for the Query Partition API (#202)
+  * `Firestore#collectionGroup(...)` has a new return type `CollectionGroup` 
+    which requires any code that previously used the method be re-compiled to
+    pick up the new signature. `CollectionGroup` extends `Query` and as such 
+    does not require your code to be updated, only the compiled class files.
+* move FirestoreAdminClient and associated classes to new artifact google-cloud-firestore-admin (#311)
+* remove deprecated v1beta1 protos and grpc client (#305)
+* remove deprecated FirestoreOptions#setTimestampsInSnapshotsEnabled (#308)
+* remove deprecated getCollections() methods (#307)
+* various renames due to generator changes
