Added

  • Nexus links of type Link.Callback are converted to and from their Nexus wire form, so they are carried through Nexus requests and responses instead of being dropped.
  • @temporalio/interceptors-opentelemetry and @temporalio/interceptors-opentelemetry-v2 now expose Workflow-only /workflow entrypoints. Existing root exports and lib/* imports remain available.
  • Experimental: External storage failures now surface as dedicated error types exported from @temporalio/common: ExternalStorageDriverError, ExternalStorageUnregisteredDriverError, and ExternalStorageReferenceError, all extending the new ExternalStorageError base type.
  • Experimental: WorkflowClient.getHandle, ActivityClient.getHandleWithOptions, and NexusClient.getHandle can infer detached handle result types and read output TypeInfo from supplied Workflow, Activity, and Nexus Operation definitions. Explicit output TypeInfo is checked against the declared handle result type.
  • Experimental: ExternalStorage now accepts cooperative concurrency limits: maxDriverOperations caps operations across its registered drivers, and maxOperationsPerMessage caps operations per top-level input or output. Drivers must acquire permits through context.limiter; the bundled S3 and GCS drivers use it.
  • Experimental: ChildWorkflowOptions.versioningOverride can pin, auto-upgrade, or one-time route a Child Workflow independently of its parent. One-time routing is also available for client-started Workflows through { oneTimeTo: WorkerDeploymentVersion }. Both require Temporal Server 1.32.0 or later. Invalid child overrides reject with InvalidVersioningOverrideError.
  • Experimental: Added list and fetchHistory interception to WorkflowClientInterceptor. list interception spans one lazy iterable consumption across pagination and early termination.
  • Experimental: NexusSerializationContext is now passed to payload converters, payload codecs, and failure converters for Nexus operation payloads, identifying the operation's endpoint, service, and operation name. Callers use it for inputs, summaries, results, and failures; handlers use it for inputs, synchronous results, and failures. A standalone handle obtained from NexusClient.getHandle has none of that information and therefore decodes without Nexus context, so contextual encodings must be self-describing and decoders must keep accepting payloads encoded without context. GetNexusOperationResultInput now carries the operation's endpoint, service, and operation when known.
  • The Workflow sandbox now exposes URLPattern, both as a global and from the url module, when the Worker runs on Node.js 23.8 or later. On older Node.js versions, URLPattern remains undefined inside Workflows.
  • Experimental: Nexus workers decode Temporal System Nexus inputs sent by the server with the System Nexus converter.
  • SearchAttributeKey is now exported from the @temporalio/common package root.
  • Experimental: Added opt-in payload caching for External Storage. Pass a PayloadCache, such as InMemoryPayloadCache, as the payloadCache option of a Client or Worker to cache External Storage payloads.
  • Experimental: Workflows can signal another Workflow and start it when absent with signalWithStartWorkflow.
  • Experimental: Workflow outbound interceptors can intercept Temporal System Nexus calls generically with startSystemNexusOperation or specifically with signalWithStartWorkflow.
  • The Workflow sandbox now exposes atob and btoa.

Changed

  • Experimental: createEventGroup(...) now takes the Event Group's ID as its first and only required argument; user-provided IDs are used verbatim and should not contain sensitive information. The optional label is a codec-encoded Payload on the second argument, the type is now EventGroup (previously EventGroupMarker), and direct Event Group attachment is supported on more APIs.
  • RetryPolicy.maximumAttempts accepts 0 as another way to specify unlimited attempts, alongside Infinity.
  • Updated unionfs from 4.5.1 to 4.6.0, @grpc/grpc-js from 1.12.4 to 1.12.7, smol-toml from 1.6.1 to 1.7.1, and tar from 7.5.11 to 7.5.21.
  • Updated ms, adding month units and fixing duration type declarations under modern Node.js module resolution.
  • @temporalio/create checks for updates in the background and displays cached notifications on subsequent interactive runs.
  • AI integrations are now maintained and released independently in temporalio/ai-integrations. @temporalio/ai-sdk and @temporalio/google-adk-agents remain as compatibility wrappers forwarding their public entrypoints to @temporalio/vercel-ai-sdk and @temporalio/google-adk. Existing import paths can be retained; new applications should use the standalone names. @temporalio/langsmith, @temporalio/openai-agents, and @temporalio/strands-agents retain their package names. The integrations' implementations, tests, and API documentation are no longer built in this repository; the two wrappers have separate forwarding tests.
  • Workers now refuse to load and execute Workflow bundles produced with a different SDK version. This unsupported practice previously resulted in subtle, hard-to-diagnose issues.

Deprecated

  • Undocumented imports through @temporalio/*/lib/* are deprecated. Where present, the wildcard remains temporarily as a compatibility fallback. @temporalio/common explicitly supports @temporalio/common/encoding, @temporalio/common/protobufs, @temporalio/common/proto-utils, and @temporalio/common/time

💥 Breaking Changes

  • Experimental: Nexus Workflow Updates now require waitForStage to be explicitly set to ACCEPTED.
  • The @temporalio/google-adk-agents compatibility wrapper now requires Node.js 22.12.0 or later and Google ADK 2.0, matching @temporalio/google-adk. The wrapper preserves import paths, but the ADK upgrade and renamed workflow random stream still require draining affected in-flight Workflows or using separate task queues for the cutover.
  • Undocumented package subpaths that are not covered by a package's explicit export map no longer resolve.
  • SDK and contrib packages now declare protobufjs (^8.7.1) and long (^5.3.2) as peer dependencies rather than relying on separately installed copies. Package managers that do not automatically install peers require applications to add these dependencies explicitly. @temporalio/proto retains its regular runtime dependencies.

Fixed

  • Workflow code that blocks the sandbox past its time limit now fails with the [TMPRL1101] deadlock diagnostic (#2426).
  • Corrected the Schedule catchupWindow documentation to state that omitted values use the Temporal Server's configured default.
  • Experimental: A Standalone Activity started from a Nexus operation handler directly through ActivityClient, rather than through TemporalNexusClient.startActivity()'s guarded call, now inherits the handler's Nexus request ID and inbound links.
  • A workflow task that arrives while a Workflow waits on a Local Activity, such as a legacy query, now waits until the current workflow task is reported. Previously it replaced that workflow task, which then timed out on the server and could leave the Workflow stuck on a nondeterminism error (temporalio/sdk-rust#1640).
  • WorkflowExecutionAlreadyStartedError now exposes the runId of the already-running Workflow Execution when the server provides it in the error details (#1838).
  • Corrected the protobufjs dependency declarations to prevent historyFromJSON failing with type must be a Type when npm installs separate protobufjs copies alongside a dependency on an older protobufjs major (#2514).
  • Fixed a race where finishing a Worker could shut down the shared Runtime while another Worker or replay was being prepared, causing replay creation to fail with a native handle type error.
  • Core: Replay now preserves which local activity results were delivered together for newly recorded histories. This prevents local activity scheduling which was conditional on local activity resolution order from assigning recorded results to different handles. Older markers keep their existing behavior.
  • Core: Workflow poll balancing now lets non-sticky pollers use capacity after sticky pollers reach their configured or autoscaled polling limit.
  • Core: Every path that fails a workflow task now only reports the failure to server on the task's first attempt, and later attempts are left to time out. Previously PayloadsTooLarge failures and history fetch failures were re-reported on every attempt.
  • Core: The workflow_task_execution_failed metric is now recorded for every failed workflow task attempt, including attempts whose failure was not sent to the server.
  • Core: Worker shutdown now drains activity completions that are still flushing their result to the server before finishing.
  • Workflow conditions are no longer evaluated in a workflow task that only delivers updates and rejects all of them.
  • JsonPayloadConverter no longer produces a payload with undefined data for values with no JSON representation, such as functions, symbols, and objects whose toJSON returns undefined. The default payload converter now throws a ValueError for these values, including symbols, which previously caused a TypeError while building the error message.
  • Update-with-Start gRPC errors now include the decoded operation error code and message in the first line of the stack trace.
  • @temporalio/create now supports comments and trailing commas in tsconfig.json files when creating projects.
  • Fixed Worker crashes when running with node --watch by ignoring unrecognized messages from Workflow Worker threads.
