Release Notes

AzureAD/microsoft-authentication-library-for-dotnet (Microsoft.Identity.Client.Extensions.Msal)

v4.56.0

==========

New Features

• MSAL.NET cache extensions (Microsoft.Identity.Client.Extensions.Msal) package has been moved to the main MSAL.NET repository (where any new issues should be created). The package version has been increased to match the main MSAL version. Along with this move, support for .NET 4.5 and .NET Core 3.1 was removed and this package now only supports .NET Standard 2.0. Additionally, Microsoft.Identity.Client.Extensions.Adal has been deprecated. See 3152, 4330.
• Added AuthenticationResult.AuthenticationResultMetadata.Telemetry that currently contains telemetry from the Windows broker (WAM). See 4159.

Bug Fixes

• Added throttling logic for acquiring tokens for managed identity (using AcquireTokenForManagedIdentity and WithAppTokenProvider) to prevent the throttling exceptions thrown by the managed identity endpoints. See 4196.
• Enabled cache synchronization by default. This helps to keep the cache consistent when a singleton confidential client application (CCA) is used with enabled external token cache serialization. The cache synchronization has a negligible performance effect when CCA is created per request. See 4268.
• Fixed an authority validation error in interactive flows when an Active Directory Federation Services (ADFS) authority with a tenant ID was used. See 4272.
• Added clarity to the Windows broker logs. See 4318.
