+==========
+### New Features
+- MSAL.NET now supports acquiring token for Client Credentials flow with a Subject Name Issuer (SNI) certificate over Mutual TLS (mTLS) for first-party applications. See [Issue #4986](https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/issues/4986)
+- Bumped NET SDK from net6 to net8, aligning MSAL.NET with the latest .NET standards and features. See [Feature Request #5025](https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/issues/5025)
+- Public API analyzer integrated to enhance API compliance and stability. See [Feature Request #4931](https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/issues/4931)

+### Bug Fixes
