microsoft-teams-cards

What's Changed

Preview release on the 2.1 train. Ports the channelData hotfix from 2.0.16.

The Teams service can send nested channelData objects as empty ({}). Because fields like AppInfo.id were required, Pydantic raised a ValidationError and the entire activity was rejected, so affected bots silently stopped responding to messages.

This release makes those inbound-only fields optional so the SDK degrades gracefully: AppInfo.id, ChannelInfo.id, TeamInfo.id, TenantInfo.id, ChannelDataSettings.selected_channel, Attachment.content_type, and EntityBase.type.

Relaxing EntityBase.type also means an entity type introduced after this SDK version no longer drops the message.

This is a preview release, published to PyPI under the next tag. Install with pip install microsoft-teams-apps==2.1.0a2.

• Make channelData subfields optional to avoid throw by Corina (@corinagum) in #564 (ported in #567)

Fixes #563. Thanks to jerbob92 for the report.

Full Changelog: v2.1.0a1...v2.1.0a2

v2.1.0a1 is the first 2.1 alpha, introducing Agent 365 identity, lifecycle, proactive messaging, and observability support. It includes the shared 2.0 maintenance baseline documented in v2.0.15; those changes are not repeated here.

Alpha: This prerelease is intended for evaluation and early integration. APIs may change before the stable 2.1 release.

Highlights

• Added Agent 365 token acquisition and inbound Entra Agent ID token validation (#457, #462) — Aamir Jawaid (@heyitsaamir).
• Added scoped Agent 365 API access plus app-level reactive and proactive send helpers (#478, #480, #505, #533) — Aamir Jawaid (@heyitsaamir).
• Added typed Agent 365 lifecycle events and app handlers (#492) — Aamir Jawaid (@heyitsaamir).
• Added OpenTelemetry diagnostics spanning inbound activities, handlers, outbound API calls, authentication, and Agent 365 context (#514, #515, #530, #516) — Aamir Jawaid (@heyitsaamir).

Changes

Agent 365 identity and authentication

• Added the agentic authentication-provider foundation (#485) and the Agent 365 API identity surface (#478) — Aamir Jawaid (@heyitsaamir).
• Standardized SDK-facing names around AgenticUser, AgenticAppInstance, and AgenticBlueprint while retaining service wire compatibility (#524) — Aamir Jawaid (@heyitsaamir).
• Standardized AgenticIdentity as the operation scope for requests, proactive sends, and scoped API clients (#533) — Aamir Jawaid (@heyitsaamir).

Messaging and lifecycle

• Unified activity sending through the API client while preserving create, update, targeted-send, and reply behavior (#479) — Aamir Jawaid (@heyitsaamir).
• Added app-level Agent 365 reactive and proactive send helpers (#480) — Aamir Jawaid (@heyitsaamir).
• Added typed agentLifecycle activity models, parsing, routing, and per-variant handlers (#492) — Aamir Jawaid (@heyitsaamir).
• Removed stale streamSequence data from final streamed messages (#539) — Corina (@corinagum).

Diagnostics and release reliability

• Added outbound API/auth spans and inbound activity/handler telemetry (#514, #515) — Aamir Jawaid (@heyitsaamir).
• Added the SDK token-provider surface and Agent 365 baggage bridge for reactive and proactive telemetry context (#530, #516) — Aamir Jawaid (@heyitsaamir).
• Hardened alpha publication with the NBGV setup fix (#540), Windows UTF-8 diagnostics port (#542, originating in #541), and locked publish dependencies (#544, originating in #543) — Aamir Jawaid (@heyitsaamir).

The Agent 365 work was integrated through #464 — Aamir Jawaid (@heyitsaamir).

Install

pip install --pre --upgrade "microsoft-teams-apps==2.1.0a1"

What's Changed

Hotfix for a regression introduced in 2.0.15.

The Teams service can send nested channelData objects as empty ({}). Because fields like AppInfo.id were required, Pydantic raised a ValidationError and the entire activity was rejected, so affected bots silently stopped responding to messages.

This release makes those inbound-only fields optional so the SDK degrades gracefully: AppInfo.id, ChannelInfo.id, TeamInfo.id, TenantInfo.id, ChannelDataSettings.selected_channel, Attachment.content_type, and EntityBase.type.

Relaxing EntityBase.type also means an entity type introduced after this SDK version no longer drops the message.

If you are on 2.0.15, upgrading is recommended.

Changes

APIs and activity handling

• Flattened client method chains to reduce call hops (#502) — Lily Du (@lilyydu).
• Deprecated skip_auth in favor of the unauthenticated-request option (#501) and removed typed extras from message activity input (#507) — Aamir Jawaid (@heyitsaamir).
