+# Whats new v0.15.0
+* Added helper class for Exchange Online/Office 365 OAuth with Exchange RBAC with Apps Support (This is latest Microsoft Guideline)
+    - This RBAC method is APP only which uses Client Credential Flow and not user specific token
+    - You can still get user specific access token by delegation and pass token to `OAuthCredentials`
+* updated `@ewsjs/xhr` version to `3.1.0` (dependency audit update)
+
+```ts
+import { ExchangeService, OAuthCredentials, ExchangeVersion } from "ews-javascript-api";
+import { EwsOAuthHelper } from "ews-javascript-api/lib/EwsOAuthHelper";
+
+const oAuthHelper = new EwsOAuthHelper({ clientId: '', clientSecret: '', tenantId: '' });
+const token = await oAuthHelper.getAppAccessToken();
+const ews = new ExchangeService(ExchangeVersion.);
+ews.Credentials =new OAuthCredentials(token.accessToken);
+await ews.<method>();
+```
