Bumps the temporal group with 6 updates in the / directory:

Package From To
@temporalio/activity 1.21.1 1.22.0
@temporalio/client 1.21.1 1.22.0
@temporalio/common 1.21.1 1.22.0
@temporalio/testing 1.21.1 1.22.0
@temporalio/worker 1.21.1 1.22.0
@temporalio/workflow 1.21.1 1.22.0

Updates @temporalio/activity from 1.21.1 to 1.22.0

Release notes

Sourced from @​temporalio/activity's releases.

v1.22.0

What's Changed

Added

  • Experimental: Added TypeInfo and TransferTypeConverter to @temporalio/common for converting application values to and from serialization-friendly transfer types and supplying converter-specific hints.
  • Workers can now configure the number of activity slots reserved for eager execution per workflow task with maxEagerActivityReservationsPerWorkflowTask. Setting it to zero disables eager activity execution.
  • UpdateWorkflow-backed Nexus operations. A Temporal Nexus operation can now be backed by a Workflow Update via TemporalNexusClient.getWorkflowHandle(...).update(...), in addition to a Workflow run. The Update request carries the Nexus request ID (for deduplication), the request links, and a completion callback bearing the operation token, so the Update's completion is delivered back to the Nexus caller. Only asynchronous, ACCEPTED-stage updates are supported (a callback URL is required); an update that has already completed is returned synchronously, and a completed-with-error update (e.g. a validation rejection) surfaces as a failed Nexus operation. Cancellation is customizable via the cancelWorkflowUpdate handler option; the default rejects with a NOT_IMPLEMENTED handler error.
  • @temporalio/ai-sdk: listToolsActivity/callToolActivity now reuse a single MCP client connection across repeated invocations for the same server instead of creating and closing one on every call. Configure the idle window via the new mcpConnectionIdleTimeout option on createActivities and AiSdkPluginOptions (defaults to 5 minutes); pass mcpConnectionIdleTimeout: 0 to opt out and restore the original behavior for MCP servers/transports that don't tolerate a reused or concurrent session.

Changed

  • Updated Core to 65b25ada (temporal-core 0.6.0)

Fixed

  • strands: Declare zod as a peer dependency.
  • workflow-streams: WorkflowStream.onPoll no longer serves a stale log index for a poll that was parked across a truncate() call, which could silently skip events.
  • Workflows no longer retain completion state when a child Workflow fails or is cancelled before starting.
  • Local Activity tests now use makeTestFunction to manage their test environment.

Security

  • Bumped the vendored quinn-proto in @temporalio/core-bridge's Cargo.lock from 0.11.14 to 0.11.15, clearing GHSA-4w2j-m93h-cj5j / RUSTSEC-2026-0185 (unbounded out-of-order stream reassembly DoS) for downstream image scanners.
