<\/li>\n<\/ul>\nEnvironment variable support for localization files<\/h3>\n
Developers can now integrate environment variables<\/strong> into their localized JSON files using the {{your_env_var}} syntax. During local debugging, provisioning, and publishing, Teams Toolkit resolves these variables dynamically. This ensures your application is well-equipped to adapt to different deployment environments.<\/p>\n

<\/p>\nIntegrated debugging for declarative agents<\/h3>\n
Debugging declarative agents is now more seamless than ever with integrated debugging support in Visual Studio Code. This enhancement allows developers to:<\/p>\n
- \n
- Visualize responses and stack traces directly within the IDE.<\/li>\n
- Troubleshoot efficiently without needing to leave the development environment.

<\/li>\n<\/ul>\nRegenerate actions for declarative agents<\/h3>\n
Keep your declarative agents up-to-date effortlessly! With the integration of Microsoft Kiota<\/strong>, Teams Toolkit now enables developers to regenerate actions, ensuring alignment with the latest features and capabilities.<\/p>\n
Enhancements<\/h2>\n
- \n
- Improved script Action Output with Native TTY Terminal UX<\/strong>: We\u2019ve enhanced the script action output by transitioning to the native TTY terminal user experience<\/strong>, addressing previous rendering issues in the Visual Studio Code output channel.<\/li>\n
- Enhanced teams-js SDK with Treeshaking Support<\/strong>: Teams Toolkit now includes an updated teams-js SDK, enabling treeshaking<\/strong> to optimize bundled packages. Unused TeamsJS functions are removed, boosting app performance and reducing bundle size.<\/li>\n
- Improved Authentication Actions for Declarative Agents<\/strong>:\n
- \n
- Expanded authentication options<\/strong> for action generation, including support for API keys in headers or queries, as well as bearer tokens.<\/li>\n
- Enhanced support for registering OAuth configurations, with updated identity URIs in the format api:\/\/auth-{authGUID}.<\/li>\n<\/ul>\n<\/li>\n
- Updated Validation Rules for Action Generation<\/strong>: To provide more flexibility, the following rules were updated:\n
- \n
- Removed nested object validation.<\/li>\n
- Removed JSON schema validation for non-JSON post bodies.<\/li>\n
- Relaxed circular reference validation.<\/li>\n
- Allowed HTTP server URLs in OpenAPI description files.<\/li>\n
- Enabled scaffolding of declarative agent projects with unsupported authentication.<\/li>\n
- Allowed APIs with multiple authentication methods.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Bug fixes<\/h2>\n
