+
+#### New Additions to the Sample App Gallery
+
+- **SSO Enabled Tab via APIM Proxy**: This addition showcases how to build a single-page web application with a single sign-on feature leveraging Azure API Management service as a proxy to perform on-behalf-of flow, eliminating the need for a dedicated backend.

+
+#### Enhanced Sample App Contribution Process
+
+In addition to these two new sample projects, we have simplified the process for the community to contribute samples by updating a configuration file. You can now submit your sample app to the gallery by following the [Teams Toolkit Sample App Contribution Guidelines](https://github.com/OfficeDev/TeamsFx-Samples/blob/dev/CONTRIBUTING.md). We are excited to see more sample apps from the community! 🥳

+
+#### TeamsFx SDK for .NET ([`Microsoft.TeamsFx`](https://www.nuget.org/packages/Microsoft.TeamsFx)) `v2.2.0`
