New Features

Added support in MSAL for dSTS authority See 3198. Enabled Azure.Identity (Azure SDK) to benefit from MSAL.NET token cache when used for Managed Identity See 3137.

Experimental Features

MSAL.NET now has a new WAM preview which is an abstraction layer based on MSAL C++ with support for Proof-of-Possession access tokens. This fixes some issues with current WAM implementation. See 3192 and wiki.

Fixed a bug in instance discovery by adding pre-production environment (PPE) domains to known endpoints. See 3265.
