 ## Changelog - SDK Version 3.0.0
 ### Breaking changes
 **1. Authentication Process Update:**
-* Previously, when using this SDK, we had to pass `authenticationEndpoint` which is used by SDK internally for fetching security parameters i.e `signature`, `token`, and `expire`.
 * In version 3.0.0, we have deprecated the use of the `authenticationEndpoint` parameter. Instead, the SDK now introduces a new parameter named `authenticator`. This parameter expects an asynchronous function that resolves with an object containing the necessary security parameters i.e `signature`, `token`, and `expire`.
-* Now `ref` needs to passed instead of `inputRef` in IKUpload component
+* Now `ref` needs to be passed instead of `inputRef` in the IKUpload component
