What's new for the Bot Framework SDKs

  • Article

APPLIES TO: SDK v4

The Bot Framework SDKs for C#, JavaScript, Python, and Java are an Open Source SDK that enables developers to model and build sophisticated conversations using C#, Java, JavaScript, or Python.

For release notes for each version, see the C# releases, JavaScript releases, Python release, and Java releases pages.

Note

The Bot Framework JavaScript, C#, and Python SDKs will continue to be supported, however, the Java SDK is being retired with final long-term support ending in November 2023.

Existing bots built with the Java SDK will continue to function.

For new bot building, consider using Microsoft Copilot Studio and read about choosing the right copilot solution.
