- Blobs: Added support for blob container immutability and legal hold policies.
- Blob/Queue: Added OAuth token support for authentication(Please note that this feature is available in preview).
- All (Desktop): Added support for specifying Proxy on OperationContext, for per-request proxy scenarios.

Changes in 9.1.1:
- Table: Updated Table related APIs to use the default Json Serializer settings.
- Table: Fixed a bug introduced after OData dependencies were removed, where support for double.NaN, double.PositiveInfinity and double.NegativeInfinity were lost.

- Blobs : Added support for soft delete feature. If a delete retention policy is enabled through the set service properties API, then blobs or snapshots can be deleted softly and retained for a specified number of days, before being permanently removed by garbage collection.
- Queues: Added support for infinite TTL on queue messages.
- All:  When a storage request fails, the error code may now be retrieved directly from the RequestResult and StorageException classes. This error code is populated even in cases where there is no ExtendedErrorInformation available, such as in calls to FetchAttributes.
- All: Upgarded NewtonSoft.json dependency to 10.0.2.
- All: Upgraded Netstandard dependency to 1.6.1.
- All (RT/NetCore): Improved performance by avoiding Task.Run
- Blobs (RT/NetCore): Fixed an infinite loop bug for StartCopyAsync API on PageBlob.

Changes in 8.7.0:
- Blobs: Parsing the snapshot parameter when creating a CloudBlockBlob from a URI is now case insensitive
- Blobs (Desktop): Added a new API supporting downloading a blob to a file by making concurrent service requests.
- Blobs (Desktop): Fixed a race-condition where cancelling a blob upload could result in deadlock.
- Blobs: Fixed StorageException when storing encrypted blobs with Formatting.Indented set in default JsonSerializerSettings.
- Blobs/Files: Added support for progress notification in async upload and download APIs.


Changes in 8.6.0 :
- Tables : Added support for Byte type property in TableEntity Flatten/ConvertBack methods.
- Blobs : Added support for the last time blobTier was modified.

Changes in 8.5.0 :
- Files: Added support for creating the snapshot of a share. See the service documentation for more information on how to use this API.

Changes in 8.4.0 :
- BlockBlobs: For Blob Storage Accounts, added support for getting and setting the tier on a block blob.
- All: Added a property called CustomUserAgent to the OperationContext class to provide the option for users to prepend a customized value to the existing UserAgent header value.

Changes in 8.3.0 :
- All(Netstandard): Updated the hashing algorithm to IncrementalHash instead of the original method which required buffering the data for MD5 calculations.
- All: Fixed a race condition in the resume-download logic where a failure during downloads could lead to corrupted data.
- Tables: Removed dependencies on OData libraries.  Added full async parsing to table API's.

Changes in 8.2.1 :
- All: Fixed a bug where empty metadata headers would lead to an infinite loop when trying to list blobs on a container.

Changes in 8.2.0 :
- All: Support for 2017-04-17 REST version. Please see our REST API documentation and blogs for information about the related added features. If you are using the Storage Emulator, please update to Emulator version 5.2.
- Files: Added support for server side encryption.
- PageBlobs: For Premium Accounts only, added support for getting and setting the tier on a page blob. The tier can also be set when creating or copying from an existing page blob.
- Tables (NetCore): Fixed a bug where the empty etag added to the table delete operation would throw an exception on Xamarin/Mono. 
- All: Fixed a bug where calling OpenWrite with an IfNotExists access condition on an existing block blob only fails when the blob is committed. Now it fails with error 409 as soon as OpenWrite is called.
- Files (WinRT/NetCore): Calling CreateIfNotExistsAsync on a root directory no longer throws the error 405. It returns false if the share exists, or throws 404 if not.
- All: Connection string support expanded to allow AccountName to be specified with SharedAccessSignature and DefaultEndpointsProtocol.  In this case, SharedAccessSignature is used for credentials, while having both DefaultEndpointsProtocol and AccountName allows the library to infer a set of default endpoints.  Additionally, we have added support for BlobSecondaryEndpoint, QueueSecondaryEndpoint, TableSecondaryEndpoint, and FileSecondaryEndpoint.  Specifying a secondary endpoint requires the specification of the corresponding primary.
- All: The use of DefaultEndpointsProtocol in a connection string is now optional in the case where endpoints would be automatically generated; if missing, a value of https will be inferred.  When the parsed account settings in such a case are used to generate a connection string, the value of DefaultEndpointsProtocol will be explicitly included.
- Tables: Added TableEntityAdapter<T> class to allow writing and reading simple or complex objects to Azure Table Storage without the need to implement ITableEntity interface or inherit from TableEntity class.

Changes in 8.1.4 :
- All (Desktop): Fixed a regression in the executor caused by disposing the SendStream during parallel operations.

Changes in 8.1.3 :
- Blobs (Desktop) : Fixed a bug where the MaximumExecutionTime was not honored, leading to infinite wait, if due to a failure, e.g., a network failure after receiving the response headers, server stopped sending partial response.
- All (Desktop) : Fixed a memory leak issue where the SendStream was not being disposed during retries, cancellations and Table Operations.

Changes in 8.1.1 :
- All (NetStandard/NetCore): Removed Microsoft.Data.Services.Client as a temporary fix to ODataLib dependency incompatibility with NetStandard.

- All: Decoupled StorageExtendedErrorInformation methods using OData to prevent the dependency from loading for Blobs, Queues, and Files.

- Files: Changed Exists() calls on CloudFileDirectory objects to populate metadata. This was already being done for CloudFiles and CloudFileShares.
- All: (WinRT) Removed the static CloudStorageAccount.Create method. Please use the instance level consructor instead.
- Blobs: Removed the IAsyncOperation* overloads for GetPageRangesDiffAsync APIs.
- Tables: Numerous changes in Table Service error codes and messages.

Issues fixed in 3.1.0.1 :

  - All: Fixed an issue that was causing the Cloud{BlobContainer|Queue|Table|BlockBlob|PageBlob} names to be set incorrectly when the absolute Uri was passed to the Get{Container|Queue|Table|BlockBlob|PageBlob}Reference methods. This also ensures that the SharedAccessSignature which includes the canonicalized names of these resources is calculated correctly.
  - All: Removed the System.Data.Services.Client dependency from the Nuget package.
  - Queues: Added an overload to GetSharedAccessSignature that takes only the SharedAccessQueuePolicy in CloudQueue.

Issues fixed in 3.1.0 : 

  - All: Added the ability to choose which SAS Version to use when generating Shared Access Signatures (either the 2012-02-12 or 2013-08-15 versions).
  
Issues fixed in 3.0.3 :

  - All: Fixed an issue that was causing a deadlock because the cancellation registration was being de-registered while holding on to a lock that the cancellation callback was waiting on.
  - All: Fixed an issue where parsing exception information out of the response stream while using async was blocking on IO calls.
  - All (WP): Fixed an issue with cancellation and timeout during upload and download causing a thread to hang. HttpWebRequest.Abort is not called during stream operations anymore.
  - Blobs: Streams opened with OpenRead methods use the user-provided buffer pooling implementation.
  - Blobs: If the parent of a blob is the container, Cloud{BlockBlob|PageBlob|BlobDirectory}.Parent returns a valid CloudBlobDirectory with an empty prefix. Similarly, container.GetDirectoryReference("") gets a valid CloudBlobDirectory representing the container.
  - Tables (Perf): Fixed an issue where the entity properties were being enumerated twice during table write operations while using JSON.
  - Tables (Perf): Parse the URI for the account name only once in the client constructor and store it so that all table operations can use the stored value.
  
Issues fixed in 3.0.2 :

  - All (WP): Fixed an issue causing ArgumentOutOfRangeException in many APIs.
  - Queues: Fixed an issue causing NullReferenceException when trying to re-create an existing queue.
  - Tables: Fixed an issue with TableServiceContext causing NullReferenceException when the error response cannot be parsed.
  - Tables (RT): Do not allow users to set JsonFullMetadata format on RequestOptions in RT, because JSON is not supported on the RT library yet.
