What's New

Adds tool context access and memory search, removes UI component props

Breaking Changes

  • `anchorTraceId` removed from ThreadViewByTrace, TraceThreadPanel, and ThreadTrace components
  • `ThreadTrace.LoadMoreSentinel` removed; use `pageSize` and `onLoadOlder` for pagination control

New Features

  • Tools can now read full conversation via `agent.getMessages()` in execution context
  • Observational memory history search now supports group filtering and explicit ordering
  • Memory recall can page through observation groups using 'before'/'after' direction
  • New accessible form field primitives (Field, Fieldset, Form, SearchInput) added to Playground UI
  • Channel adapters now support bot display name lookup via `botDisplayName`

Upgrade Notes

Update ThreadViewByTrace, TraceThreadPanel, and ThreadTrace components to remove `anchorTraceId`. Replace `ThreadTrace.LoadMoreSentinel` with `pageSize` and `onLoadOlder` for pagination control.
