Highlights

Standalone Activities are now GA

With the following updates, Standalone Activities are now generally available (GA)!

  • Renamed the standalone activity client.StartActivityOptions.Details option to StaticDetails,
    and client.ActivityExecutionDescription.GetDetails to GetStaticDetails.
  • Added missing description fields: ExecutionTime and TotalHeartbeatCount.
  • Corrected stand-alone activity API documentation to use activity terminology, document that
    GetActivityHandleOptions.RunID may be empty to target the latest run, and describe
    TerminateActivityOptions.Reason as a termination reason.
  • Added opt-in payload fields to client.DescribeActivityOptions: IncludeInput,
    IncludeOutcome, IncludeHeartbeatDetails and IncludeLastFailure.
  • Standalone activity client calls now supply converter.ActivitySerializationContext when encoding
    and decoding activity payloads: ExecuteActivity (input and static summary/details),
    ActivityHandle.Describe (heartbeat details, last failure, and static summary/details), and
    ActivityHandle.Get (result and failure).
  • Standalone activities started from a redelivered Nexus operation handler now reuse the Nexus
    request ID, preventing duplicate Nexus links when an idempotent start resolves to the original run.
  • client.ActivityHandle now supports operator commands for standalone activities: Pause,
    Unpause, UpdateOptions and RestoreOriginalOptions. Operator commands remain experimental.
  • Standalone Activities as Nexus operations remain experimental.
Local Activity memory savings

Local activity scheduling no longer uses a fixed 100,000-entry task queue. The queue now grows
with demand, avoiding both the up-front allocation and a possible worker deadlock when the queue
and all local activity execution slots were full.

Other Notable Changes

Added
  • Worker heartbeats now report the Go runtime version (plus RoadRunner, when the SDK is embedded in
    a RoadRunner binary), detected hosting environments (Docker, Kubernetes, and common cloud
    platforms), and the operating system and architecture. This is sent
    once per worker with the first heartbeat accepted by the server and can be turned off with
    client.Options.DisableWorkerEnvironmentInfo.
  • Added converter.NexusSerializationContext support for Nexus callers and handlers. Callers use
    it for inputs, results, and failures; handlers use it for inputs, synchronous results, and
    failures. Asynchronous handler results and detached standalone handles are not yet supported.
    Standalone USE_EXISTING handles use their start request's context.
  • Added temporal.NewPayloadValidationError to create non-retryable application errors with
    optional structured details for payload validation failures. Passing nil omits details.
  • Added Go 1.27+ generic methods on the experimental temporalnexus.NexusClient for starting
    workflow-, activity-, and workflow-update-backed Nexus operations.
  • Workflow task completions larger than the gRPC request size limit are now paginated automatically
    when the namespace supports it. Paginated workflow task completions require Temporal Server 1.32.0
    or later.
  • The temporal_activity_execution_failed and temporal_local_activity_execution_failed worker
    metrics now carry a failure_reason attribute. Each is now split into one time series per
    reason, which may affect existing dashboards.
  • Added support for Workflow Queries as Nexus Operations.
💥 Breaking Changes
  • Raised the minimum supported Go version from 1.25.4 to 1.26.0.
  • Description payload fields that previously came back unconditionally are now opt-in and must be
    requested via client.DescribeActivityOptions: GetHeartbeatDetails (IncludeHeartbeatDetails)
    and GetLastFailure (IncludeLastFailure).
  • Experimental external storage: converter.StorageDriverSelector.SelectDriver now receives a
    converter.StorageDriverSelectContext instead of a converter.StorageDriverStoreContext.
    Update the parameter type; the new type carries the same Context and Target fields.
  • Local activity results are now serialized with the local activity's ActivitySerializationContext
    (IsLocal=true) instead of the workflow serialization context. Users of a context-aware
    DataConverter or PayloadCodec whose encoding depends on the serialization context (for example
    context-derived encryption keys or AAD) may fail to decode local activity results recorded in
    histories written by earlier SDK versions, both on replay and when continuing an open workflow.
  • Experimental workflow.WorkflowRandomStream's Uint64 now derives its value by calling Read
    internally instead of the underlying generator's Uint64 method directly, giving Read/Uint64
    interleaving on the same stream a stable, well-defined byte ordering (previously undefined per the
    standard library ChaCha8.Read doc). This only changes output for a Uint64 call that immediately
    follows a Read call whose length is not a multiple of 8 bytes on the same stream; pure Uint64
    streams and 8-byte-aligned interleaving are unaffected. Open workflows created on SDK v1.48.0+ that
    hit the affected pattern may compute a different value, and therefore may make a different decision,
    on replay after upgrading.
  • Activity, local activity and child workflow serialization contexts are now applied to the
    worker-configured DataConverter and FailureConverter instead of the converter already carrying
    the current workflow context. A context-aware converter that composed contexts (deriving its state
    from both the workflow and the activity context) now sees only the activity or child workflow
    context, and one whose WithSerializationContext returned a converter that is no longer
    context-aware now receives the activity or child workflow context it previously never saw.
Fixed
  • Workflow autoscaling now favors sticky polls when sticky work is backlogged, while allowing
    normal polls to use spare slots once sticky reaches its autoscaling target.
  • The PayloadDownloadDuration and PayloadUploadDuration fields on the workflow task duration log
    now report the wall-clock time external storage was in flight. Previously each batch's duration was
    summed, over-reporting the time whenever storage operations ran concurrently.
  • temporal.IsWorkflowExecutionAlreadyStartedError now detects wrapped
    serviceerror.WorkflowExecutionAlreadyStarted errors.
  • Malformed Nexus link errors now log the link URL and parse error under stable structured fields.
  • Legacy query task processing failures are now reported through RespondQueryTaskCompleted instead of
    RespondWorkflowTaskFailed, allowing query callers to receive the failure instead of timing out.
  • Local activity results are now serialized with the local activity's ActivitySerializationContext
    (IsLocal=true) on both ends. Previously the result was encoded with the plain worker data converter
    but decoded through the workflow serialization context, so a context-aware DataConverter or
    PayloadCodec saw mismatched contexts for local activity results.
  • Workflow replays no longer retain one-shot workflow state in the process-wide sticky cache.
  • Added disabled-by-default SDK flag 9 for deterministic workflow child-context cancellation.
    Currently no behavior is changed by default, a future PR will flip this flag on by
    default.
  • DefaultFailureConverter.FailureToError now correctly decodes LastHeartbeatDetails for a
    reset-workflow failure. Previously the raw payload proto was treated as a single detail value,
    so calling Details() on the resulting ApplicationError returned ErrTooManyArg instead of
    decoding it.
  • Added documentation that function literals (closures) shouldn't be registered as
    workflow functions or activity functions without an alias.
  • Query results are now checked against the server's blob-size error limit after
    external storage has had a chance to offload them, matching how update and activity
    results of the same size already behaved. A query result large enough to be offloaded
    to client.Options.ExternalStorage is now stored instead of failing locally with
    TMPRL1103. As a consequence, a StorageDriver failure while storing an oversized
    query result now fails the workflow task instead of returning a failed query result.
