0.14.0

Added 0.14.0

• Add card authentication sign-in support: AdaptiveCardBackendHandlers opens the sign-in URL via urlOpener and completeSignin(state:) POSTs a signin invoke (signin/verifyState for Teams) whose replaceCard response swaps in the returned card. Adds AdaptiveCardInvokeKind.signin, AdaptiveCardInvokeRequest.fromSignin, and connectionName field on the request model.

Docs 0.14.0

• README: "How actions reach your handlers" is now a short host-focused summary (when your callback fires vs. not) that links to the canonical per-action table and dispatch diagrams in docs/actions-architecture.md. The full GenericAction → InheritedAdaptiveCardHandlers table + a component and sequence diagram moved there; docs/backend-host-integration.md gained sequence diagrams for the invoke and sign-in round-trips.

0.13.0

Added 0.13.0

• Action.Http transport (deprecated/legacy action) — Action.Http is the original Adaptive Cards HTTP action model (schema v1.0), superseded by Action.Execute (Universal Action Model, schema v1.4) and still used by Outlook Actionable Messages. New AdaptiveHttpExecutor interface and default HttpAdaptiveHttpExecutor (built on package:http) perform the card-authored GET/POST. AdaptiveCardBackendHandlers gains an optional httpExecutor and wires the core onHttp callback: on success it honors CARD-UPDATE-IN-BODY: true by replacing the rendered card (reusing onCardReplaced + cardValidator), and surfaces CARD-ACTION-STATUS / non-2xx failures via onError. Response bodies are byte-capped.

Changed 0.13.0

• Docs: README now has an Implementation status section summarizing Phase 1 / Phase 2 coverage and linking to the central status matrix.

Tests 0.13.0

• Expanded AdaptiveCardBackendHandlers tests to cover Execute / Refresh / onChange invoke kinds and both error paths (missing mounted card state, backend post failure), bringing backend_handlers.dart to full coverage.

0.12.0

Security 0.12.0

• Bounded backend response decoding: HttpAdaptiveCardBackendClient gains maxResponseBytes (default 1 MiB) and decodes via decodeJsonMapWithLimit, throwing AdaptiveJsonTooLargeException on oversized bodies instead of decoding unbounded untrusted JSON.
• Optional replaceCard validator: AdaptiveCardInvokeResponse.applyTo and AdaptiveCardBackendHandlers.wrap accept an AdaptiveCardValidator; a backend-supplied replacement card that fails validation is rejected (AdaptiveCardInvokeResponseParseException) and never rendered.

0.11.0

• no changes yet

0.10.0

• Initial release: AdaptiveCardInvokeRequest, PlainJson and Teams adapters, AdaptiveCardInvokeResponse with applyTo, HttpAdaptiveCardBackendClient, and AdaptiveCardBackendHandlers.
• AdaptiveCardBackendHandlers: optional onRefresh wired to the same backend invoke path as Action.Execute (via ExecuteActionInvoke payload).
