What's new for the Bot Framework SDKs


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.


The Bot Framework Python and Java SDKs are being retired with final long-term support ending in November 2023. Only critical security and bug fixes within this repository will be undertaken. Existing bots built with these SDKs will continue to function.

For new bot development, consider using Power Virtual Agents. For more information, see The future of bot building.
