### Bugs Fixed
* Pollers that use the `Location` header won't consider `http.StatusRequestTimeout` a terminal failure.
* `runtime.Poller[T].Result` won't consider non-terminal error responses as terminal.
## 1.11.0 (2024-04-01)
### Features Added
* Added `StatusCodes` to `arm/policy.RegistrationOptions` to allow supporting non-standard HTTP status codes during registration.
* Added field `InsecureAllowCredentialWithHTTP` to `azcore.ClientOptions` and dependent authentication pipeline policies.
* Added type `MultipartContent` to the `streaming` package to support multipart/form payloads with custom Content-Type and file name.
### Bugs Fixed
* `runtime.SetMultipartFormData` won't try to stringify `[]byte` values.
* Pollers that use the `Location` header won't consider `http.StatusTooManyRequests` a terminal failure.
### Other Changes
* Update dependencies.
## 1.10.0 (2024-02-29)
### Features Added
* Added logging event `log.EventResponseError` that will contain the contents of `ResponseError.Error()` whenever an `azcore.ResponseError` is created.
* Added `runtime.NewResponseErrorWithErrorCode` for creating an `azcore.ResponseError` with a caller-supplied error code.
* Added type `MatchConditions` for use in conditional requests.
### Bugs Fixed
* Fixed a potential race condition between `NullValue` and `IsNullValue`.
* `runtime.EncodeQueryParams` will escape semicolons before calling `url.ParseQuery`.
### Other Changes
* Update dependencies.
## 1.9.2 (2024-02-06)
### Bugs Fixed
* `runtime.MarshalAsByteArray` and `runtime.MarshalAsJSON` will preserve the preexisting value of the `Content-Type` header.
### Other Changes
* Update to latest version of `internal`.
## 1.9.1 (2023-12-11)
### Bugs Fixed
* The `retry-after-ms` and `x-ms-retry-after-ms` headers weren't being checked during retries.
### Other Changes
* Update dependencies.
## 1.9.0 (2023-11-06)
### Breaking Changes
> These changes affect only code written against previous beta versions of `v1.7.0` and `v1.8.0`
* The function `NewTokenCredential` has been removed from the `fake` package. Use a literal `&fake.TokenCredential{}` instead.
* The field `TracingNamespace` in `runtime.PipelineOptions` has been replaced by `TracingOptions`.
### Bugs Fixed
* Fixed an issue that could cause some allowed HTTP header values to not show up in logs.
* Include error text instead of error type in traces when the transport returns an error.
* Fixed an issue that could cause an HTTP/2 request to hang when the TCP connection becomes unresponsive.
* Block key and SAS authentication for non TLS protected endpoints.
* Passing a `nil` credential value will no longer cause a panic. Instead, the authentication is skipped.
* Calling `Error` on a zero-value `azcore.ResponseError` will no longer panic.
* Fixed an issue in `fake.PagerResponder[T]` that would cause a trailing error to be omitted when iterating over pages.
* Context values created by `azcore` will no longer flow across disjoint HTTP requests.
### Other Changes
* Skip generating trace info for no-op tracers.
* The `clientName` paramater in client constructors has been renamed to `moduleName`.
## 1.9.0-beta.1 (2023-10-05)
### Other Changes
* The beta features for tracing and fakes have been reinstated.
## 1.8.0 (2023-10-05)
### Features Added
* This includes the following features from `v1.8.0-beta.N` releases.
* Claims and CAE for authentication.
* New `messaging` package.
* Various helpers in the `runtime` package.
* Deprecation of `runtime.With*` funcs and their replacements in the `policy` package.
* Added types `KeyCredential` and `SASCredential` to the `azcore` package.
* Includes their respective constructor functions.
* Added types `KeyCredentialPolicy` and `SASCredentialPolicy` to the `azcore/runtime` package.
* Includes their respective constructor functions and options types.
### Breaking Changes
> These changes affect only code written against beta versions of `v1.8.0`
* The beta features for tracing and fakes have been omitted for this release.
### Bugs Fixed
* Fixed an issue that could cause some ARM RPs to not be automatically registered.
* Block bearer token authentication for non TLS protected endpoints.
### Other Changes
* Updated dependencies.
## 1.8.0-beta.3 (2023-09-07)
### Features Added
* Added function `FetcherForNextLink` and `FetcherForNextLinkOptions` to the `runtime` package to centralize creation of `Pager[T].Fetcher` from a next link URL.
### Bugs Fixed
* Suppress creating spans for nested SDK API calls. The HTTP span will be a child of the outer API span.
### Other Changes
* The following functions in the `runtime` package are now exposed from the `policy` package, and the `runtime` versions have been deprecated.
* `WithCaptureResponse`
* `WithHTTPHeader`
* `WithRetryOptions`
## 1.7.2 (2023-09-06)
### Bugs Fixed
* Fix default HTTP transport to work in WASM modules.
## 1.8.0-beta.2 (2023-08-14)
### Features Added
* Added function `SanitizePagerPollerPath` to the `server` package to centralize sanitization and formalize the contract.
* Added `TokenRequestOptions.EnableCAE` to indicate whether to request a CAE token.
### Breaking Changes
> This change affects only code written against beta version `v1.8.0-beta.1`.
* `messaging.CloudEvent` deserializes JSON objects as `[]byte`, instead of `json.RawMessage`. See the documentation for CloudEvent.Data for more information.
> This change affects only code written against beta versions `v1.7.0-beta.2` and `v1.8.0-beta.1`.
* Removed parameter from method `Span.End()` and its type `tracing.SpanEndOptions`. This API GA'ed in `v1.2.0` so we cannot change it.
### Bugs Fixed
* Propagate any query parameters when constructing a fake poller and/or injecting next links.
## 1.7.1 (2023-08-14)
## Bugs Fixed
* Enable TLS renegotiation in the default transport policy.
## 1.8.0-beta.1 (2023-07-12)
### Features Added
- `messaging/CloudEvent` allows you to serialize/deserialize CloudEvents, as described in the CloudEvents 1.0 specification: [link](https://github.com/cloudevents/spec)

* The beta features for CAE, tracing, and fakes have been omitted for this release.
## 1.7.0-beta.2 (2023-06-06)
### Breaking Changes
> These changes affect only code written against beta version v1.7.0-beta.1
* Method `SpanFromContext()` on type `tracing.Tracer` had the `bool` return value removed.
* This includes the field `SpanFromContext` in supporting type `tracing.TracerOptions`.
* Method `AddError()` has been removed from type `tracing.Span`.
* Method `Span.End()` now requires an argument of type `*tracing.SpanEndOptions`.
## 1.6.1 (2023-06-06)
### Bugs Fixed
* Fixed an issue in `azcore.NewClient()` and `arm.NewClient()` that could cause an incorrect module name to be used in telemetry.
### Other Changes
* This version contains all bug fixes from `v1.7.0-beta.1`
## 1.7.0-beta.1 (2023-05-24)
### Features Added
* Restored CAE support for ARM clients.
* Added supporting features to enable distributed tracing.
* Added func `runtime.StartSpan()` for use by SDKs to start spans.
* Added method `WithContext()` to `runtime.Request` to support shallow cloning with a new context.
* Added field `TracingNamespace` to `runtime.PipelineOptions`.
* Added field `Tracer` to `runtime.NewPollerOptions` and `runtime.NewPollerFromResumeTokenOptions` types.
* Added field `SpanFromContext` to `tracing.TracerOptions`.
* Added methods `Enabled()`, `SetAttributes()`, and `SpanFromContext()` to `tracing.Tracer`.

# Release History
## 1.6.0 (2024-06-10)
### Features Added
* `NewOnBehalfOfCredentialWithClientAssertions` creates an on-behalf-of credential
that authenticates with client assertions such as federated credentials
### Breaking Changes
> These changes affect only code written against a beta version such as v1.6.0-beta.4
* Removed `AzurePipelinesCredential` and the persistent token caching API.
They will return in v1.7.0-beta.1
### Bugs Fixed
* Managed identity bug fixes
## 1.6.0-beta.4 (2024-05-14)
### Features Added
* `AzurePipelinesCredential` authenticates an Azure Pipeline service connection with
workload identity federation
## 1.6.0-beta.3 (2024-04-09)
### Breaking Changes
* `DefaultAzureCredential` now sends a probe request with no retries for IMDS managed identity
environments to avoid excessive retry delays when the IMDS endpoint is not available. This
should improve credential chain resolution for local development scenarios.
### Bugs Fixed
* `ManagedIdentityCredential` now specifies resource IDs correctly for Azure Container Instances
## 1.5.2 (2024-04-09)
### Bugs Fixed
* `ManagedIdentityCredential` now specifies resource IDs correctly for Azure Container Instances
### Other Changes
* Restored v1.4.0 error behavior for empty tenant IDs
* Upgraded dependencies
## 1.6.0-beta.2 (2024-02-06)
### Breaking Changes
> These changes affect only code written against a beta version such as v1.6.0-beta.1
* Replaced `ErrAuthenticationRequired` with `AuthenticationRequiredError`, a struct
type that carries the `TokenRequestOptions` passed to the `GetToken` call which
returned the error.
### Bugs Fixed
* Fixed more cases in which credential chains like `DefaultAzureCredential`
should try their next credential after attempting managed identity
authentication in a Docker Desktop container
### Other Changes
* `AzureCLICredential` uses the CLI's `expires_on` value for token expiration
## 1.6.0-beta.1 (2024-01-17)
### Features Added
* Restored persistent token caching API first added in v1.5.0-beta.1
* Added `AzureCLICredentialOptions.Subscription`
## 1.5.1 (2024-01-17)
### Bugs Fixed
* `InteractiveBrowserCredential` handles `AdditionallyAllowedTenants` correctly
## 1.5.0 (2024-01-16)
### Breaking Changes
> These changes affect only code written against a beta version such as v1.5.0-beta.1
* Removed persistent token caching. It will return in v1.6.0-beta.1
### Bugs Fixed
* Credentials now preserve MSAL headers e.g. X-Client-Sku
### Other Changes
* Upgraded dependencies
## 1.5.0-beta.2 (2023-11-07)
### Features Added
* `DefaultAzureCredential` and `ManagedIdentityCredential` support Azure ML managed identity
* Added spans for distributed tracing.
## 1.5.0-beta.1 (2023-10-10)
### Features Added
* Optional persistent token caching for most credentials. Set `TokenCachePersistenceOptions`
on a credential's options to enable and configure this. See the package documentation for
this version and [TOKEN_CACHING.md](https://aka.ms/azsdk/go/identity/caching) for more
details.
* `AzureDeveloperCLICredential` authenticates with the Azure Developer CLI (`azd`). This
credential is also part of the `DefaultAzureCredential` authentication flow.
## 1.4.0 (2023-10-10)
### Bugs Fixed
* `ManagedIdentityCredential` will now retry when IMDS responds 410 or 503
## 1.4.0-beta.5 (2023-09-12)
### Features Added
* Service principal credentials can request CAE tokens
### Breaking Changes
> These changes affect only code written against a beta version such as v1.4.0-beta.4
* Whether `GetToken` requests a CAE token is now determined by `TokenRequestOptions.EnableCAE`. Azure
SDK clients which support CAE will set this option automatically. Credentials no longer request CAE
tokens by default or observe the environment variable "AZURE_IDENTITY_DISABLE_CP1".
### Bugs Fixed
* Credential chains such as `DefaultAzureCredential` now try their next credential, if any, when
managed identity authentication fails in a Docker Desktop container
([#21417](https://github.com/Azure/azure-sdk-for-go/issues/21417))
## 1.4.0-beta.4 (2023-08-16)
### Other Changes
* Upgraded dependencies
## 1.3.1 (2023-08-16)
### Other Changes
* Upgraded dependencies
## 1.4.0-beta.3 (2023-08-08)
### Bugs Fixed
* One invocation of `AzureCLICredential.GetToken()` and `OnBehalfOfCredential.GetToken()`
can no longer make two authentication attempts
## 1.4.0-beta.2 (2023-07-14)
### Other Changes
* `DefaultAzureCredentialOptions.TenantID` applies to workload identity authentication
* Upgraded dependencies
## 1.4.0-beta.1 (2023-06-06)
### Other Changes
* Re-enabled CAE support as in v1.3.0-beta.3
## 1.3.0 (2023-05-09)

When no default browser is available, `az login` will use the device code
authentication flow. This can also be selected manually by running `az login --use-device-code`.
#### Authenticate via the Azure Developer CLI
Developers coding outside of an IDE can also use the [Azure Developer CLI](https://aka.ms/azure-dev) to authenticate. Applications using the `DefaultAzureCredential` or the `AzureDeveloperCLICredential` can use the account logged in to the Azure Developer CLI to authenticate calls in their application when running locally.
To authenticate with the Azure Developer CLI, run `azd auth login`. On a system with a default web browser, `azd` will launch the browser to authenticate. On systems without a default web browser, run `azd auth login --use-device-code` to use the device code authentication flow.

## Token caching
Token caching is an `azidentity` feature that allows apps to:
* Cache tokens in memory (default) or on disk (opt-in).
* Improve resilience and performance.
* Reduce the number of requests made to Microsoft Entra ID to obtain access tokens.
For more details, see the [token caching documentation](https://aka.ms/azsdk/go/identity/caching).
## Troubleshooting
### Error Handling
Credentials return an `error` when they fail to authenticate or lack data they require to authenticate. For guidance on resolving errors from specific credential types, see the [troubleshooting guide](https://aka.ms/azsdk/go/identity/troubleshoot).
For more details on handling specific Azure Active Directory errors please refer to the
Azure Active Directory
[error code documentation](https://docs.microsoft.com/azure/active-directory/develop/reference-aadsts-error-codes).
For more details on handling specific Microsoft Entra errors, see the Microsoft Entra [error code documentation](https://learn.microsoft.com/entra/identity-platform/reference-error-codes).

## Token caching in the Azure Identity client module
*Token caching* is a feature provided by the Azure Identity library that allows apps to:
- Improve their resilience and performance.
- Reduce the number of requests made to Microsoft Entra ID to obtain access tokens.
- Reduce the number of times the user is prompted to authenticate.
When an app needs to access a protected Azure resource, it typically needs to obtain an access token from Entra ID. Obtaining that token involves sending a request to Entra ID and may also involve prompting the user. Entra ID then validates the credentials provided in the request and issues an access token.
Token caching, via the Azure Identity library, allows the app to store this access token [in memory](#in-memory-token-caching), where it's accessible to the current process, or [on disk](#persistent-token-caching) where it can be accessed across application or process invocations. The token can then be retrieved quickly and easily the next time the app needs to access the same resource. The app can avoid making another request to Entra ID, which reduces network traffic and improves resilience. Additionally, in scenarios where the app is authenticating users, token caching also avoids prompting the user each time new tokens are requested.
### In-memory token caching
*In-memory token caching* is the default option provided by the Azure Identity library. This caching approach allows apps to store access tokens in memory. With in-memory token caching, the library first determines if a valid access token for the requested resource is already stored in memory. If a valid token is found, it's returned to the app without the need to make another request to Entra ID. If a valid token isn't found, the library will automatically acquire a token by sending a request to Entra ID. The in-memory token cache provided by the Azure Identity library is thread-safe.
**Note:** When Azure Identity library credentials are used with Azure service libraries (for example, Azure Blob Storage), the in-memory token caching is active in the `Pipeline` layer as well. All `TokenCredential` implementations are supported there, including custom implementations external to the Azure Identity library.
#### Caching cannot be disabled
As there are many levels of caching, it's not possible disable in-memory caching. However, the in-memory cache may be cleared by creating a new credential instance.
### Persistent token caching
> Only azidentity v1.5.0-beta versions support persistent token caching
*Persistent disk token caching* is an opt-in feature in the Azure Identity library. The feature allows apps to cache access tokens in an encrypted, persistent storage mechanism. As indicated in the following table, the storage mechanism differs across operating systems.
| Operating system | Storage mechanism |
|------------------|---------------------------------------|
| Linux | kernel key retention service (keyctl) |
| macOS | Keychain |
| Windows | DPAPI |
By default the token cache will protect any data which is persisted using the user data protection APIs available on the current platform.
However, there are cases where no data protection is available, and applications may choose to allow storing the token cache in an unencrypted state by setting `TokenCachePersistenceOptions.AllowUnencryptedStorage` to `true`. This allows a credential to fall back to unencrypted storage if it can't encrypt the cache. However, we do not recommend using this storage method due to its significantly lower security measures. In addition, tokens are not encrypted solely to the current user, which could potentially allow unauthorized access to the cache by individuals with machine access.
With persistent disk token caching enabled, the library first determines if a valid access token for the requested resource is already stored in the persistent cache. If a valid token is found, it's returned to the app without the need to make another request to Entra ID. Additionally, the tokens are preserved across app runs, which:
- Makes the app more resilient to failures.
- Ensures the app can continue to function during an Entra ID outage or disruption.
- Avoids having to prompt users to authenticate each time the process is restarted.
>IMPORTANT! The token cache contains sensitive data and **MUST** be protected to prevent compromising accounts. All application decisions regarding the persistence of the token cache must consider that a breach of its content will fully compromise all the accounts it contains.
#### Example code
See the [package documentation](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.6.0-beta.2#pkg-overview) for example code demonstrating how to configure persistent caching and access cached data.
### Credentials supporting token caching
The following table indicates the state of in-memory and persistent caching in each credential type.
**Note:** In-memory caching is activated by default. Persistent token caching needs to be enabled as shown in [this example](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.5.0-beta.1#example-package-PersistentCache).
