Bug FixesSection of the release
  • Fixed resume attachment validation: malformed or missing attachment payloads in saved transcripts are now dropped with an error log rather than causing resume to fail (search for "the session transcript appears partially corrupt")
  • Fixed the workflow VM sandbox to properly handle MCP-thrown errors in resolveDeep's auto-await loop — a script ending on an unawaited MCP call no longer silently swallows the error (search for "mcpToolError: true")
  • Fixed request cancellation in the load-balancing request router: when a request can't be sent and falls back to local handling, the outstanding remote request slot is now explicitly cancelled via cancelRequest() (search for "i.cancelRequest(a)")
  • Fixed the bridge prependUserMessage method: adding a prepended message now wakes the async input reader immediately rather than waiting for the next chunk, which fixes a race in remote workflow dispatch (search for "prependWaker")
  • Fixed fleet view: deleting a pinned background agent now also unpins it before deletion, preventing stale pin state (search for "Gos(o.id, !1).catch")
  • Fixed skills/list validation to also reject oversized fields (previously only checked for malformed/missing required fields) (search for "malformed, missing, or oversized fields")
  • Fixed discoveryCache leaking into serialized MCP server config: the field is now deleted before the config is stored (search for "delete a.discoveryCache")
  • Fixed injectControlResponse to return a boolean indicating whether the response was consumed — previously it always returned void, making it impossible for callers to detect no-op responses (search for "injectControlResponse")
  • Fixed word-wrap rendering in the terminal output renderer to use the correct source array (E vs v) when iterating tokens without wrapping (search for "R = E.map")
  • Fixed the workflow VM context builder to use the correct budget_usd registration path, ensuring budget tracking is available in the right VM scope (search for "ab(\"budget_usd\"")
