- Added LINQ support for aggregation queries (COUNT, MIN, MAX, SUM, and AVG).
- Fix for a memory leak issue for the ConnectionPolicy object caused by the use of event handler.
- Fix for an issue wherein UpsertAttachmentAsync was not working when ETag was used.
- Fix for an issue wherein cross partition order-by query continuation was not working when sorting on string field.
- Added support for aggregation queries (COUNT, MIN, MAX, SUM, and AVG). See Aggregation support.
- Lowered minimum throughput on partitioned collections from 10,100 RU/s to 2500 RU/s.
- Fix for an issue wherein some of the cross-partition queries were failing in the 32-bit host process.
- Fix for an issue wherein the session container was not being updated with the token for failed requests in Gateway mode.

- Client side performance fixes for increasing the read and write throughput of the requests.
- Fix for an issue wherein the session container was not being updated with the token for failed requests.
- Added support for the SDK to work in a 32-bit host process. Note that if you use cross partition queries, 64-bit host processing is recommended for improved performance.
- Improved performance for scenarios involving queries with a large number of partition key values in an IN expression.
- Populated various resource quota stats in the ResourceResponse for document collection read requests when PopulateQuotaInfo request option is set.
- Minor performance fix for the CreateDocumentCollectionIfNotExistsAsync API introduced in 1.11.0.

- Added LINQ support for StringEnumConverter, IsoDateTimeConverter and UnixDateTimeConverter while translating predicates.
- Various SDK bug fixes.
- Fixed an issue that caused the following NotFoundException: The read session is not available for the input session token. This exception occurred in some cases when querying for the read-region of a geo-distributed account.
- Exposed the ResponseStream property in the ResourceResponse class, which enables direct access to the underlying stream from a response.
- Modified the ResourceResponse, FeedResponse, StoredProcedureResponse and MediaResponse classes to implement the corresponding public interface so that they can be mocked for test driven deployment (TDD).
- Fixed an issue that caused a malformed partition key header when using a custom JsonSerializerSettings object for serializing data.
- Fixed an issue that caused long running queries to fail with error: Authorization token is not valid at the current time.

Changes to support Order By
- LINQ provider support for OrderBy() or OrderByDescending()
IndexingPolicy to support Order By
NB: Possible breaking change
If you have existing code that provisions collections with a custom indexing policy, then your existing code will need to be updated to support the new IndexingPolicy class. If you have no custom indexing policy, then this change does not affect you.

Release & Retirement dates
Microsoft will provide notification at least 12 months in advance of retiring an SDK in order to smooth the transition to a newer/supported version.
New features and functionality and optimizations are only added to the current SDK, as such it is recommended that you always upgrade to the latest SDK version as early as possible.
Any request to DocumentDB using a retired SDK will be rejected by the service.

1. How will customers be notified of the retiring SDK?
Microsoft will provide 12 month advance notification to the end of support of the retiring SDK in order to facilitate a smooth transition to a supported SDK. Further, customers will be notified through various communication channels – Azure Management Portal, Developer Center, blog post, and direct communication to assigned service administrators.
2. Can customers author applications using a "to-be" retired DocumentDB SDK during the 12 month period?
Yes, customers will have full access to author, deploy and modify applications using the "to-be" retired DocumentDB SDK during the 12 month grace period. During the 12 month grace period, customers are advised to migrate to a newer supported version of DocumentDB SDK as appropriate.
3. Can customers author and modify applications using a retired DocumentDB SDK after the 12 month notification period?
After the 12 month notification period, the SDK will be retired. Any access to DocumentDB by an applications using a retired SDK will not be permitted by the DocumentDB platform. Further, Microsoft will not provide customer support on the retired SDK.
4. What happens to Customer’s running applications that are using unsupported DocumentDB SDK version?
Any attempts made to connect to the DocumentDB service with a retired SDK version will be rejected.
5. Will new features and functionality be applied to all non-retired SDKs
New features and functionality will only be added to new versions. If you are using an old, non-retired, version of the SDK your requests to DocumentDB will still function as previous but you will not have access to any new capabilities.
6. What should I do if I cannot update my application before a cut-off date
We recommend that you upgrade to the latest SDK as early as possible. Once an SDK has been tagged for retirement you will have 12 months to update your application. If, for whatever reason, you cannot complete your application update within this timeframe then please contact the DocumentDB Team and request their assistance before the cutoff date.
