Releases

@cloudflare/ai-chat@0.7.0

Minor Changes

• #1484 364a45d Thanks @whoiskatrin! - Add cancelOnClientAbort to useAgentChat. Generic browser/client stream cleanup is now local-only by default so server turns can continue and resume; explicit stop() still cancels the server turn. Set cancelOnClientAbort: true to make generic client aborts cancel the server turn.

Patch Changes

• #1376 6561a3f Thanks @hrushikeshdeshpande! - Avoid throwing when chat stream resume negotiation/replay races with a closed WebSocket connection.

• #1487 752e25a Thanks @whoiskatrin! - Close the original WebSocket chat transport stream when the socket disconnects before a terminal response, preventing recovered chat continuations from leaving useAgentChat stuck in streaming state.

• #1481 12365dd Thanks @whoiskatrin! - Fixed approval auto-continuation streams so reasoning chunks keep a valid reasoning-start before reasoning-delta sequence when continuing from an assistant message that already has reasoning, and preserve the continuation reasoning in the final persisted message.

• #1483 5373f5c Thanks @whoiskatrin! - Allow Think agent-tool children to complete without emitting assistant text. Non-chat tool-step agents can now provide structured output through getAgentToolOutput, with summaries derived from assistant text, string output, structured output, or an empty string.

  Fix useAgentChat().isServerStreaming cleanup when a resumed stream first enters the fallback observer path and later becomes transport-owned.

@cloudflare/think@0.6.0

Minor Changes

• #1456 787e73d Thanks @mattzcarey! - Stop applying pruneMessages({ toolCalls: "before-last-2-messages" }) to the model context by default. The previous default silently stripped client-side tool results (no execute, output supplied via addToolOutput) from any turn beyond the second, breaking multi-turn flows where the user's choices live in those tool results (see #1455). truncateOlderMessages still runs as before, so context cost stays bounded.

  This is a behavior change. Subclasses that relied on the old aggressive pruning can opt back in from beforeTurn:

  import { pruneMessages } from "ai";
  
  beforeTurn(ctx) {
    return {
      messages: pruneMessages({
        messages: ctx.messages,
        toolCalls: "before-last-2-messages"
      })
    };
  }

• #1517 449b421 Thanks @threepointone! - Wrap Think.chat() RPC turns in chat recovery fibers and persist their stream chunks so interrupted sub-agent turns can recover partial output. ChatOptions.tools has been removed from the TypeScript API; runtime options.tools values passed by legacy callers are ignored with a warning. Define durable tools on the child agent or use agent tools for orchestration.

• #1511 bf3860c Thanks @threepointone! - Add durable programmatic submissions for Think. submitMessages() now provides fast durable acceptance, idempotent retries, status inspection, cancellation, and cleanup for server-driven turns that should continue after the caller returns.

Patch Changes

• #1500 7090e9e Thanks @threepointone! - Preserve structured tool output shapes when truncating older messages or oversized persisted rows, preventing custom toModelOutput handlers from crashing or mis-replaying compacted results.

  Also harden Think's workspace read tool so legacy raw-string read outputs replay as text instead of stalling subsequent turns.

• #1483 5373f5c Thanks @whoiskatrin! - Allow Think agent-tool children to complete without emitting assistant text. Non-chat tool-step agents can now provide structured output through getAgentToolOutput, with summaries derived from assistant text, string output, structured output, or an empty string.

  Fix useAgentChat().isServerStreaming cleanup when a resumed stream first enters the fallback observer path and later becomes transport-owned.

• #1463 ab2b1db Thanks @whoiskatrin! - Avoid throwing when chat stream resume negotiation/replay races with a closed WebSocket connection. Resume protocol sends and the _handleStreamResumeAck fallback now go through sendIfOpen helpers that swallow the TypeError: WebSocket send() after close race instead of letting it propagate up through onMessage.

@cloudflare/voice@0.2.0

Minor Changes

• #1478 2c7d91b Thanks @whoiskatrin! - Add an enabled option to useVoiceAgent so React apps can delay creating and connecting a VoiceClient until async prerequisites such as capability tokens are ready.

Patch Changes

• #1458 84cb429 Thanks @whoiskatrin! - Fix Workers AI STT session edge cases for Flux and Nova 3.

  Flux now preserves the latest non-empty turn transcript from turn lifecycle events so an EndOfTurn event with an empty transcript can still emit the completed utterance. Flux StartOfTurn also drives server-side barge-in so model-detected user speech aborts active LLM/TTS playback promptly. Nova 3 now defensively normalizes finalized segment state before reading it to avoid stale teardown messages throwing during abnormal close paths.

• #1462 5f6214d Thanks @whoiskatrin! - Fix withVoice text streaming for AI SDK textStream responses so TTS audio is produced when onTurn() returns streamText(...).textStream directly.

agents@0.12.4

Patch Changes

• #1376 6561a3f Thanks @hrushikeshdeshpande! - Avoid throwing when chat stream resume negotiation/replay races with a closed WebSocket connection.

• #1509 4aa4176 Thanks @threepointone! - Prevent duplicate initial state frames during Agent WebSocket connection setup so client-originated state updates are not overwritten by stale initial state messages.

• #1476 3c48858 Thanks @whoiskatrin! - Fixed a bug that could cause client state to drift from internal Durable Object state when agent tool calls spanned a Durable Object restart. Recovery now defers user finish hooks until after agent startup and isolates hook failures so one failed mirror write does not block other recovered runs from finalizing.

• #1514 0371a6f Thanks @threepointone! - Route streamable HTTP server-to-client requests through the originating POST stream when no standalone SSE stream is available.

• #1500 7090e9e Thanks @threepointone! - Preserve structured tool output shapes when truncating older messages or oversized persisted rows, preventing custom toModelOutput handlers from crashing or mis-replaying compacted results.

  Also harden Think's workspace read tool so legacy raw-string read outputs replay as text instead of stalling subsequent turns.

• #1504 5d27b71 Thanks @threepointone! - Prune stale sub-agent schedule rows when their owning facet registry entry no longer exists.

• #1503 7b8ab51 Thanks @threepointone! - Bump PartyServer to pick up transient Durable Object routing retries and expose routingRetry configuration through getAgentByName.

@cloudflare/codemode@0.3.5

Patch Changes

• #1468 186a2a4 Thanks @mattzcarey! - Add a browser-safe codemode export with an iframe sandbox executor and browser
  tool helper. Harden iframe message handling with nonce-scoped messages, reject
  sanitized tool name collisions, and keep tools with needsApproval: false.

• #1470 1033fa2 Thanks @mattzcarey! - Resolve OpenAPI specs inside the codemode sandbox to avoid Worker Loader RPC size limits for heavily-referenced specs.

• #1508 13acffe Thanks @threepointone! - fix(codemode): harden OpenAPI sandbox ref handling
