+7.4.1
+======
+### Bug Fixes:
+- `SamlSecurityTokenHandler` and `Saml2SecurityTokenHandler` now can fetch configuration when validating SAML issuer and signature. See PR [#2412](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/pull/2412)
+- `JsonWebToken.ReadToken` now correctly checks Dot3 index in JWE. See PR [#2501](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/pull/2501)
+
+### Engineering Excellence:
+- Remove reference to `Microsoft.IdentityModel.Logging` in `Microsoft.IdentityModel.Protocols`, which already depends on it via `Microsoft.IdentityModel.Tokens`. See PR [#2508](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/pull/2508)
+- Adjust uppercase json serialization tests to fix an unreliable test method, add consistency to naming. See PR [#2512](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/pull/2512) 
+- Disable the 'restore' and 'build' steps of 'build and pack' in `build.sh`, improving speed. See PR [#2521](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/pull/2521)
