What's New
Adds default error recovery, Google Workspace toolsets, and tool-pause UX improvements.
Breaking Changes
- Durable streams no longer emit a separate tripwire chunk; clients must check `finishReason === 'tripwire'` and `output.tripwire` instead.
New Features
- Default agent error recovery with repair-first strategy and safe retries.
- Google Workspace toolsets for Docs, Drive, and Sheets.
- Observational memory can display attachments to the model.
- New `tool-call-resumed` stream chunk for better UI state management.
- Exports `findGatewayForModel` and `getGatewayId` from `@mastra/core/llm`.
Improvements
- Reliability and scale fixes for durable/evented execution.
- Invalid tool-call ID rewriting for Anthropic models.
- New `resolveSubagentModel` option with requestContext support.
- Improved reliability for background tasks via heartbeat and lease fencing.
Bug Fixes
- Reliability and scale fixes for durable/evented execution.
Upgrade Notes
Clients consuming durable streams must update logic to check `finishReason === 'tripwire'` and `output.tripwire` instead of expecting a separate chunk. The new default error recovery is enabled but can be disabled via `errorProcessorDefaults: false`.
