New Features

• Reinstate Microsoft.IdentityModel.Protocols.WsTrust as a supported 8.x package, preserving the 6.8 public API while adding current target frameworks, compatibility corrections, parser and serializer fixes, and XML resource limits. See PR #​3547.
• Add SignedHttpRequestValidationParameters.UseCaseSensitivePClaimComparison to configure Signed HTTP Request p claim path comparison per validation. The 8.x default remains case-insensitive unless callers explicitly opt into case-sensitive comparison. See PR #​3577.
• Resolve supported ML-DSA AKP keys from JsonWebKeySet and preserve structurally valid public keys for downstream cryptographic extensibility when the current runtime cannot materialize them. See PR #​3597.

Bug Fixes

• Normalize hexadecimal letter casing inside percent-encoded triplets during Signed HTTP Request p claim validation. Literal path-letter comparison remains controlled by UseCaseSensitivePClaimComparison, and p claim creation output is unchanged. See PR #​3579.
• Log expected per-key IDX10650 authentication-tag failures at Informational instead of Error during multi-key JWE decryption. Terminal all-keys-failed results continue to be reported at Error. See PR #​3582.
