 # Change log
 Change log stars with version 3.1.3
 
+## 4.2.1
+- Adding check for `FunctionNameAttribute` when executing binding for InProcess mode. There are situations where other functions can be injected that are not decorated with attribute and also execute parameter binding.
+
 ## 4.2.0
 - Removing support for STS .NET versions (7.0), as these versions are not supported by Azure Functions runtime.
 - Removing ARM authentication support to align with Azure Functions runtime changes.
@@ -99,4 +102,4 @@ The package for Azure Functions V3+ In-Proc mode is now called `DarkLoop.Azure.F
   Azure Functions recently [added configuration](https://github.com/Azure/azure-functions-host/pull/9678) for issuer and audience validation for the default authentication flows, not the one supported by this package through `FunctionAuthorizeAttribute`, which interferes with token validation when using our own Bearer scheme token configuration.
   In prior versions, this package has functionality to clear Functions built-in configuration, but it was not enabled by default when using `AddJwtBearer(Action<JwtBearerOptions> configure, bool removeBuiltInConfig = false)`. Since the use of this package is commonly used for custom JWT token, the default value of `removeBuiltInConfig` is now `true`.
   > This functionality is now deprecated and no longer supported starting in version 4.1.0. It will be removed in future versions.
-  > Bearer scheme is now used by the Functions runtime and another one should be used for your functions.
