 ## Breaking Changes
 
 ### Supported Node version and TypeScript update
-- Microsoft Graph JS SDK requires Node.js 10 LTS or higher.
-- Updated to TypeScript 4.x.
 
-### LargeFileUploadTask 
-- Modified the `FileObject` interface which now contains the `sliceFile` function. Learn more [LargeFileUploadTask](../docs/tasks/LargeFileUploadTask.md). 
-- The `FileObject` instance passed on creation of the `LargeFileUploadTask` object should contain the implementation of the `sliceFile` function.
-- Added new classes `FileUpload` and `StreamUpload` implementing the `FileObject` interface.

 ## Changed folder paths
-- Files in `lib/es` have been moved to `lib/es/src`. The `lib` folder contains the transpiled `src` files.
-	- The `lib` contains the ES and CJS modules as follows:
-	```
-		lib
-		│
-		└─── src (CJS modules)
-		|
-		│   
-		└─── es 
-		     |___ src (ES modules)
-	 ```
-- `Range`: `src/Range` changed to `src/tasks/FileUploadTask/Range`.
-- `ImplicitMSALAuthenticationProvider`: 
-	- `src/ImplicitMSALAuthenticationProvider` changed to `src/authentication/msal/ImplicitMSALAuthenticationProvider`.
-	-  Alternatively, `ImplicitMSALAuthenticationProvider` can be imported or required from `@microsoft/microsoft-graph-client/authProviders/msal`.
-- `MSALAuthenticationProviderOptions`: 
-	- `src/MSALAuthenticationProviderOptions` changed to `src/authentication/msal/MSALAuthenticationProviderOptions`.
-	- Alternatively, `MSALAuthenticationProviderOptions` can be imported or required from `@microsoft/microsoft-graph-client/authProviders/msal`.

 ## Enhancements
 
 ### Introducing support for `@azure/identity TokenCredentials`
-- Added a `TokenCredentialAuthenticationProvider` enabling the use of `@azure/identity` `credential classes` for authentication purposes. 
-- The `TokenCredentialAuthenticationProvider` enables server-side authentication using `credential classes` such as `ClientSecretCredential` or `ClientCertificateCredential`.
-- Find the samples on how to use `TokenCredentialAuthenticationProvider` here - [TokenCredentialAuthenticationProvider samples](../samples/tokenCredentialSamples)

 ## Deprecation
 
-### Deprecating `ImplicitMSALAuthenticationProvider` 
-- Use of `ImplicitMSALAuthenticationProvider`, that is,using the implicit authorization flow is not recommended any more. [OAuth 2.0 Implicit Grant](https://oauth.net/2/grant-types/implicit/).
-- Alternatively, you can implement a `CustomAuthenticationProvider` with an auth library of your choice. Learn more using the [samples](https://github.com/microsoftgraph/msgraph-sdk-javascript#samples-and-tutorials).
