🛠️ Enhancement

Python Package Updates

In this release, added four core Python libraries used for bot development and integration:

• botbuilder-core

• botbuilder-schema

• botframework-connector

• aiohttp

These additions deliver improvements in performance, schema handling, and asynchronous operations, providing a more reliable and efficient runtime environment.

Connector Update – Tenant ID Requirement

To comply with Microsoft’s recent changes to the multi-tenant registration process, the connector structure has been extended with a tenant_id parameter.

As of July 31, 2025, all newly generated Microsoft Teams bot credentials require valid tenant ID. Existing credentials remain valid, but future registrations will not function without this field.

Detailed Version

🛠️ Enhancement

• Package Upgrades: The botbuilder libraries improve schema compatibility and connector handling, while the aiohttp update ensures better performance under high concurrency.

• Connector Change: The addition of the tenant_id field ensures that all new Microsoft Teams bot registrations align with Microsoft’s updated security and authentication requirements.

User Notices & Guidance

• For new Teams bot credentials, make sure to configure the tenant_id. Without it, authentication will fail.

• Existing bots created before this release remain unaffected.

Hints (Productivity Tips)

💡 You can find your Directory (tenant) ID in the Azure Portal under App Registrations and add it directly into your connector configuration.
