Packages Published

Package	Version	Install
@ag-ui/aws-strands	1.0.0	`npm install @ag-ui/aws-strands@1.0.0`

Audio attachments now delivered as native Strands AudioBlocks via @strands-agents/sdk 1.14.0+, detected at runtime; audio persists byte-for-byte in unified and legacy storage.
Audio input is now opt-in: delivered only when StrandsAgentConfig.audioInputSupported is true; otherwise reported in MediaDropped.
Audio attachments retain the client's original filename in native message metadata, matching image, document and video.
_runStarted now sets protocolVersion: PROTOCOL_VERSION on RUN_STARTED.
Frontend tool results now reconciled into snapshot sessions (SnapshotSessionManager), replacing synthetic placeholder messages.
Validators now sourced from @ag-ui/core/schemas, with part renames and provider-specific tool result flattening.

Peer floors for @ag-ui/core and @ag-ui/client moved to >=1.0.0; code imports @ag-ui/core/schemas, which does not exist before 1.0.
Model-class audio auto-detection and seed rebuild removed; audio no longer delivered automatically based on BedrockModel detection in some paths—set audioInputSupported explicitly.
Binary inputs retired and SDK checkpoint floor unified; re-verify media handling.

Package	Version	Install
ag_ui_strands	1.0.0	`pip install ag_ui_strands==1.0.0`
ag-ui-crewai	1.0.0	`pip install ag-ui-crewai==1.0.0`

Audio attachments now delivered as native Strands audio blocks on strands-agents 1.53.0+, persisting byte-for-byte across session managers; dropped audio reported via MediaDropped on older SDKs.
Audio input is opt-in: only delivered to BedrockModel/LlamaCppModel or when StrandsAgentConfig.audio_input_supported=True; otherwise the clip is skipped instead of failing later turns.
Original client filenames now kept for audio attachments and in native session storage, matching image, document, and video.
Tool results carrying media now replay as media rather than text; blocks are held to formats Strands accepts.
Replayed media blocks validated against supported formats; mismatched or mis-spelled formats (e.g. "PNG", "tiff") are skipped instead of becoming invalid native blocks.
Tool result content now keeps only blocks a tool result can carry, dropping unsupported audio/video arms.
RunStartedEvent now carries protocol_version=PROTOCOL_VERSION.
Fixed per-thread agents being pinned to the template's model via Strands' aux_model fallback property.

Requires ag-ui-protocol >=1.0.0; binary input parts are rejected at RunAgentInput validation, so only media parts reach the converter.
StrandsAgentConfig.audio_input_supported is now a bool defaulting to False; model-class auto-detection is removed. Enable explicitly for models that accept audio.
Audio is no longer delivered to providers whose formatters cannot carry it unless the model is Bedrock/LlamaCpp or the flag is set.

Declares protocol_version=PROTOCOL_VERSION on every RunStartedEvent, including both StreamFrameTranslator sites and the legacy bus listener.
Adapter now sources validators from @ag-ui/core/schemas, follows part renames, flattens tool result content to text where needed, and drops file sources with a warning instead of sending provider handles.
Resumed native sessions now require native frames and use unified streaming; teardown is bounded and cleanup is cancelled at its deadline.
Removed the leftover uvicorn<0.35.0 cap, allowing installation alongside packages needing uvicorn 0.35+ such as fastmcp 2.14 (floor remains 0.34.3).

Requires ag-ui-protocol>=1.0.0; the protocol floor was raised to 1.0.
RUN_STARTED events now include a protocolVersion field; consumers parsing these events should re-verify handling.
Adapter validation moved to the 1.0 models with renamed parts; tool result content is flattened to text and unsupported file sources are dropped, changing emitted output.
Resumed native sessions now require native frames.
