v1.20.3

What's Changed

Fixed

• Workflow Bundler: further strengthening of the webpack_module_cache replacement logic, addressing regressions introduced by the fix in 1.20.1.
• @temporalio/langsmith: install Workflow-bundle rewrites via compiler.webpack so they work under non-hoisting node_modules layouts (e.g. pnpm hoist=false).
• @temporalio/langsmith: emit the LangSmith run fire-and-forget rather than awaiting it, removing a yield point that reordered commands under signalWithStart.

v1.20.2

What's Changed

• fix(langsmith): resolve workflow interceptor module by absolute path by @chris-olszewski in #2181

Full Changelog: v1.20.1...v1.20.2

v1.15.1

Backport #2169 to address #2170

v1.20.1

Backport #2169 to address #2170

v1.20.0

v1.20.0

Added

• New @temporalio/langsmith package for tracing Temporal apps to LangSmith.
  It hooks the client, Workflow, and Activity interceptors so a Workflow and the Activities it runs show up
  as a single LangSmith run tree.

Changed

• protobufjs bumped to ^7.6.4
• Updated Core to 5df57f6d. Package-visible changes from this update include:
  • NativeConnection initialization now retries without gRPC gzip compression if the server
    cannot decompress the eager GetSystemInfo call.
  • Workflow replay now honors SDK flags already recorded in history even when the server does not
    advertise SDK metadata support.
  • OTLP metric export failures from Core's periodic metric reader are now logged through Core
    telemetry.
• @temporalio/openai-agents: Query handlers and update validators now derive trace span IDs from the SDK's
  replay-safe random source instead of a private seeded PRNG. This removes the old seed-collision workaround
  and gives read-only handlers distinct, well-formed span IDs.

What's Changed

Added

• Nexus operation link propagation for signals. When a Nexus operation handler signals a workflow
  (including signal-with-start), the inbound Nexus request links are now forwarded onto the signaled
  workflow so its history events link back to the caller, and the link the server returns for the
  signaled event is attached to the caller workflow's Nexus operation history event. This makes the
  caller and callee mutually navigable in the UI for signal-based Nexus operations.
• Added @temporalio/interceptors-opentelemetry-v2 to support OpenTelemetry JS SDK 2.
• Expose continue-as-new backoff start interval.
• add nondeterministic unsafe.random for read-only contexts.

Breaking Changes

• WorkflowHandle.runId in @temporalio/nexus is now an optional property to support creating a handle using only a workflow ID.
• Enable gRPC gzip compression by default. Can be disabled by passing grpcCompression: { codec: none } when constructing a NativeConnection. ⚠️ If using a proxy that doesn't support gzip compression we suggest upgrading to 1.20.0 which will downgrade the connection.
• bump required Node version to 20.3.0.

Changed

• Standalone Nexus operation links are now formatted to align with server side support.
• Standalone Nexus operation links are now forwarded on start workflow and signal requests.
• protobufjs bumped to 7.6.2
• Rename @temporalio/openai-agents tracing sink to the reserved _temporal prefix

Fixed

• fix(openai-agents): correct misleading legacy-query comment in resolveQueryKey
• avoid logging NativeConnection on worker startup

Other

• docs(worker): fix broken link to production deploy guide by @ASHISHTOMER0817 in #2134
