+#### New Additions to the Sample App Gallery

+
+#### Enhanced Sample App Contribution Process
+
+In addition to these two new sample projects, we have set up a self-service process for any contributor to submit request to onboard new samples. 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! 🥳

+
+#### Teams Toolkit CLI ([`@microsoft/teamsfx-cli`](https://www.npmjs.com/package/@microsoft/teamsfx-cli)) `v2.0.3@beta`
+
+In this beta release of Teams Toolkit CLI, we have implemented a number of usability improvements based on your valuable feedback.
+
+- **Hierarchical Command Structure**: Commands have been reorganized into a hierarchical structure.
+
+- **Redesigned Help Command**: The help command has been redesigned for improved readability, including vertical and column alignments for commands and their descriptions, refined subcommands, command options/arguments, and global options, support for option abbreviations, indicators of required options, and inclusion of example commands.
+    ![CLI-2](https://github.com/OfficeDev/TeamsFx/assets/11220663/e365832f-cd38-4a6d-89ca-ebd8721a48e8)
+
+- **New `teamsfx list` Command**: We've added the `teamsfx list` command for reviewing available project templates and samples.
+    ![CLI-1](https://github.com/OfficeDev/TeamsFx/assets/11220663/8b9da73e-2159-4276-9719-5688a36b4c28)
+

+
+- **Improved Compatibility**: Color issues for terminals with light-colored backgrounds have been fixed, and suggestions for misspelled commands have been added.
+
+- **Global Config Commands Removal**: The global config commands, `teamsfx config set` and `teamsfx config get` have been removed and are now incorporated into global options.
+
+- **Upload custom applications across Microsoft 365**: We've added the ability to upload custom applications across Microsoft 365, including Teams, Outlook, and the Microsoft 365 app via `teamsfx m365` commands.
+
+#### TeamsFx SDK for .NET ([`Microsoft.TeamsFx`](https://www.nuget.org/packages/Microsoft.TeamsFx)) `v2.2.0`
+
+- Deprecated `MsGraphAuthProviders` with `GraphServiceClient` since token credentials are natively supported in [Microsoft Graph SDK for .NET](https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/c3baee460e0420f93b151548a07754310447e448/src/Microsoft.Graph/GraphServiceClient.cs#L47).
+- Added `validationEnabled` param to `getPagedInstallationAsync` API for better performance to support the use case of sending notifications in large scale tenants.
+
+#### Bug Fixes
+
+- Fixed an issue where Teams Toolkit CLI always creates new project folder in a different directory than the current one. ([#9586](https://github.com/OfficeDev/TeamsFx/pull/9586))

+- Fixed an issue with build warnings in `TeamsFx` SDK. ([#9707](https://github.com/OfficeDev/TeamsFx/pull/9707))
+- Fixed an issue where the depency of `@microsoft/microsoft-graph-client` used in the `@microsoft/teamsfx` and `@microsoft/teamsfx-react` SDK were not updated to the latest version. ([#9720](https://github.com/OfficeDev/TeamsFx/pull/9720))
