### Microsoft Teams support (GA)
Microsoft Teams support | [docs][00] | [C# sample][00] | [JS sample][00] :: Build and connect intelligent bots to interact with Microsoft Teams users naturally through chat. The Bot Framework SDK v4.6 release adds native support for building Teams bots allowing users to bring bots into their channel or group chat conversations. By adding a bot to a team or chat, all users of the conversation can take advantage of the bot functionality right in the conversation.
## Bot Framework Channels
- [Direct Line Speech General Availability](https://aka.ms/streaming-extensions) | [docs](https://docs.microsoft.com/azure/bot-service/directline-speech-bot?view=azure-bot-service-4.0): Bot Framework and Microsoft's Speech Services provide a channel that enables streamed speech and text bi-directionally from the client to the bot application using WebSockets.
### Dynamics 365 Virtual Agent for Customer Service (??)
[Virtual Agent for Customer Service](https://docs.microsoft.com/en-us/dynamics365/ai/customer-service-virtual-agent/overview), built on the Microsoft Bot Framework, makes it easy to create bots that address common support issues. It removes the complexity of exposing teams to the nuances of conversational AI and the need to write complex code. It provides exceptional customer service with intelligent, adaptable virtual agents.
- [A Private Direct Line: Direct Line App Serive Extension (preview)](https://portal.azure.com) | [docs](https://aka.ms/directline-ase): A version of Direct Line that isolates your bot from other traffic on the Bot Service by running Direct Line on its Azure App Service. This both improves latency, and allows bots to participate in Azure VNET configuraitons. A VNET lets developers create your own private space in Azure and is crucial to your cloud network as it offers isolation, segmentation, and other key benefits.
### Adaptive Dialog (Preview)
- [Adaptive Dialog][47] | [docs][48] | [C# samples][49] :: Adaptive Dialogs enable developers to build conversations that can be dynamically changed as the conversation progresses.
- Adaptive dialog now includes trigger to action pairs, recognizer, and generator. This makes every adaptive dialog self-contained and easy to compose.
- Events have been cleaned up to correspond to activity level events and dialog level events.
- Regex recognizer now supports 10+ prebuilt entity types
- Triggers, actions have been refined based on feedback
- Stability improvements and bug fixes.
### Language Generation (Preview)
- [Language Generation][43] | [docs][44] | [C# samples][45] :: Language Generation enable developers to separate logic used to generate bot's respones including ability to define multiple variations on a phrase, execute simple expressions based on context, refer to conversational memory.
- Structured template support - with this you can now use Langauge Generation for multi-modal responses including spoken response, displayed response as well as UI cards etc.
- Ability to import and refer to .lg files. This helps streamline organization of templates, its composability and re-usability.
- Stability improvements and bug fixes.
## Bot Framework SDK
- [Adaptive Dialog (SDK v4.6 preview)](https://github.com/Microsoft/BotBuilder-Samples/tree/master/experimental/adaptive-dialog#readme) | [docs](https://github.com/Microsoft/BotBuilder-Samples/tree/master/experimental/adaptive-dialog/docs) | [C# samples](https://github.com/Microsoft/BotBuilder-Samples/tree/master/experimental/adaptive-dialog/csharp_dotnetcore):
Adaptive Dialog now allow developers to dynamically update conversation flow based on context and events. This is especially useful when dealing with conversation context switches and interruptions in the middle of a conversation.
- [Bot Framework Python SDK (preview)](https://github.com/microsoft/botbuilder-python) | [samples](https://github.com/Microsoft/botbuilder-python/tree/master/samples): The Python SDK now supports OAuth, Prompts, CosmosDB, and includes all major functionality in SDK 4.5. Plus, samples to help you learn about the new features in the SDK.
### Common Expression Language (Preview)
- [Common Expression Language][40] | [api][41] :: Both Adaptive dialogs and Language Generation rely on and use a common expression language to power bot conversations.
- New prebuilt functions (jpath, eval)
- Stability improvements and bug fixes.

## Bot Framework CLI Tools (GA)
The new [BF CLI](https://aka.ms/bfcli) tool replaces legacy standalone tools used to manage Bot Framework bots and related services. We have ported most tools and are in process of porting the rest. BF CLI aggregates the collection of cross-platform tools into one cohesive and consistent interface.
For the 4.6 release, the following commands were ported over:
| BF [New Command] | Old Tool |
| ---------------------------- | -------- |
