  connections more readily.
- Adding `PrepareDecorator` to target custom BaseURLs.
- Adding ACR suffix to public cloud environment.
- Updating Glide dependencies.

## v7.2.5
- Fixed the Active Directory endpoint for the China cloud.

## v7.0.4
- Better error messages for long running operation failures

## v7.0.3
- Corrected DoPollForAsynchronous to properly handle the initial response

## v7.0.2

## v7.0.1

- Fixed polling support for GET calls
- Changed format name from TimeRfc1123 to TimeRFC1123

## v7.0.0
- Added ByCopying responder with supporting TeeReadCloser
- Rewrote Azure asynchronous handling
- Reverted to only unmarshalling JSON
- Corrected handling of RFC3339 time strings and added support for Rfc1123 time format

The `json.Decoder` does not catch bad data as thoroughly as `json.Unmarshal`. Since
`encoding/json` successfully deserializes all core types, and extended types normally provide
their custom JSON serialization handlers, the code has been reverted back to using
`json.Unmarshal`. The original change to use `json.Decode` was made to reduce duplicate
code; there is no loss of function, and there is a gain in accuracy, by reverting.

Additionally, Azure services indicate requests to be polled by multiple means. The existing code
only checked for one of those (that is, the presence of the `Azure-AsyncOperation` header).
The new code correctly covers all cases and aligns with the other Azure SDKs.

## v6.1.0
- Introduced `date.ByUnmarshallingJSONDate` and `date.ByUnmarshallingJSONTime` to enable JSON encoded values.

## v6.0.0
- Completely reworked the handling of polled and asynchronous requests
- Removed unnecessary routines
- Reworked `mocks.Sender` to replay a series of `http.Response` objects
- Added `PrepareDecorators` for primitive types (e.g., bool, int32)

Handling polled and asynchronous requests is no longer part of `Client#Send`. Instead new
`SendDecorators` implement different styles of polled behavior. See`autorest.DoPollForStatusCodes`
and `azure.DoPollForAsynchronous` for examples.

## v5.0.0
- Added new RespondDecorators unmarshalling primitive types
- Corrected application of inspection and authorization PrependDecorators

## v4.0.0
- Added support for Azure long-running operations.
- Added cancelation support to all decorators and functions that may delay.
- Breaking: `DelayForBackoff` now accepts a channel, which may be nil.

## v3.1.0
- Add support for OAuth Device Flow authorization.
- Add support for ServicePrincipalTokens that are backed by an existing token, rather than other secret material.
- Add helpers for persisting and restoring Tokens.
- Increased code coverage in the github.com/Azure/autorest/azure package

## v3.0.0
- Breaking: `NewErrorWithError` no longer takes `statusCode int`.
- Breaking: `NewErrorWithStatusCode` is replaced with `NewErrorWithResponse`.
- Breaking: `Client#Send()` no longer takes `codes ...int` argument.
- Add: XML unmarshaling support with `ByUnmarshallingXML()`
- Stopped vending dependencies locally and switched to [Glide](https://github.com/Masterminds/glide).
  Applications using this library should either use Glide or vendor dependencies locally some other way.
- Add: `azure.WithErrorUnlessStatusCode()` decorator to handle Azure errors.
- Fix: use `net/http.DefaultClient` as base client.
- Fix: Missing inspection for polling responses added.
- Add: CopyAndDecode helpers.
- Improved `./autorest/to` with `[]string` helpers.
- Removed golint suppressions in .travis.yml.

## v2.1.0
