Workflow Development Kit Updates & Release Notes

@workflow/[email protected]

• #2266 a00d169 @VaguelySerious - Add an opt-in optimistic-concurrency guard for event creation (WORKFLOW_PRECONDITION_GUARD=1): replay-context event creations send a stateUpdatedAt snapshot timestamp, and the runtime reloads the event log and retries (then falls back to a queue re-invocation) when the backend reports a newer out-of-band event with a 412 PreconditionFailedError.
• #2929 1933e29 @VaguelySerious - Report run-started-to-first-step (rsfs) and final-scheduling-replay (finalSchedulingReplay) latency telemetry on step completion events.
• #2153 6b8efd5 @rchasman - Record cross-run lineage when start() is called from inside a workflow or step: the new run is tagged with $parentRunId (its direct parent) and inherits the parent's $rootRunId, so a daisy chain or fan-out of any depth groups under one root id.
• #2943 fd107b9 @VaguelySerious - Fixed TTFS latency telemetry reporting 0 for runs with region-tagged run IDs.

• #2914 f72184d @karthikscale3 - Add WORKFLOW_LOCAL_RECOVER_ACTIVE_RUNS env var as a fallback for the recoverActiveRuns option, so re-enqueueing of pending/running runs on startup can be disabled without a custom world module.

#2901 9242ddb @karthikscale3 - Move client-observed stream telemetry to core: chunk_rtt on the flush span, connect_ms on the read span, and new workflow.stream.close and workflow.stream.read.complete spans. Dedupe @opentelemetry/api to one workspace instance.

• #1981 9da2d76 @TooTallNate - start() now delegates run ID generation to world.createRunId(options) when the world provides it, falling back to a monotonic ULID otherwise. The full options bag is passed through so worlds can read whichever fields they recognise. Adds a new region option that worlds may consume — when set, it is also forwarded onto the queue options so the initial workflow message is routed to the matching region.

@workflow/[email protected]

• #2896 c31e30c @TooTallNate - Show world-specific run fields (e.g. region on Vercel) in workflow inspect output via the new optional World.describeRun hook.

@workflow/[email protected]

• #2903 f2be954 @karthikscale3 - Add analytics.attributes.list() for attribute key discovery, and an attributes key=value filter to analytics.runs.list().
• #1981 9da2d76 @TooTallNate - Add optional createRunId(options?) to the World interface and region to QueueOptions. Worlds can now mint custom run IDs (reading whichever start-option fields they recognise) and route messages to a specific region.
• #2899 ac41e7d @TooTallNate - Parse timezone-naive analytics timestamps as UTC so CLI and local web output shows correct times in any timezone.
• #2896 c31e30c @TooTallNate - Show world-specific run fields (e.g. region on Vercel) in workflow inspect output via the new optional World.describeRun hook.

@workflow/[email protected]

• #2903 f2be954 @karthikscale3 - Add analytics.attributes.list() for attribute key discovery, and an attributes key=value filter to analytics.runs.list().
• #2193 a4d8de0 @VaguelySerious - Add opt-in WORKFLOW_SEQUENTIAL_REPLAYS env var (also enabled by the WORKFLOW_SAFE_MODE=1 umbrella flag when not set explicitly). When set to 1, flow (orchestrator) routes are limited to one invocation per run at a time via a per-run queue topic and maxConcurrency: 1 on the flow trigger. Step routes are unaffected.
• #1981 9da2d76 @TooTallNate - Implement World.createRunId to mint region-tagged ULIDs, preferring an explicit options.region from start(), then the VERCEL_REGION environment variable, and finally defaulting to iad1 so run IDs are always tagged with a concrete, routable region. The queue now routes each message to the region encoded in the payload's tagged run ID (or to an explicit opts.region override), instead of the previous hard-coded iad1.
• #2896 c31e30c @TooTallNate - Show world-specific run fields (e.g. region on Vercel) in workflow inspect output via the new optional World.describeRun hook.

#2891 4a43e39 @karthikscale3 - Emit a client-observed workflow.stream.flush span per stream-write batch, with a buffer_dwell_ms attribute separating client-side batching cost from network/server time. Log under DEBUG=workflow:* when @opentelemetry/api fails to load in world-vercel.

#2882 0b956f6 @VaguelySerious - Rename experimental_setAttributes to setAttributes — the attributes feature is no longer experimental. The old name remains available as a deprecated alias.

@workflow/[email protected]

#2888 7a1ea5a @ctgowrie - Use the active queue namespace when re-enqueuing workflow runs during world startup recovery.

• #2850 f28150c @karthikscale3 - Report step progress alongside step-to-step overhead latency telemetry.
• #2872 36c63af @mitul-s - Record the source run on replays: recreateRunFromExisting now stamps replayedFromRunId into the new run's executionContext (and start accepts a matching option) so tooling can surface a run as a replay and link back to its origin.
• #2790 145835b @NathanColosimo - Centralize workflow event type classifiers and event-data payload field helpers.
• #2687 9958424 @Osamaali313 - Fix extractStreamIds overflowing the stack on circular references. The hydrated observability data it walks comes from devalue, which preserves circular and repeated references, so a step result containing a cycle would crash run inspection (wf inspect and the web dashboard) with a RangeError. The traversal now tracks visited containers and skips cycles.
• #2848 6603628 @VaguelySerious - Fix duplicate inline step execution when a hook or wait wakes a run while the step is still running (#2780). The lazy step_started now records the owning queue message ID, and wake replays schedule a delayed backstop for in-flight inline steps instead of immediately re-dispatching them. Disable with WORKFLOW_INLINE_OWNERSHIP=0.
• #2874 48fcc4e @karthikscale3 - Add a namespace option to start(), recreateRunFromExisting(), reenqueueRun(), and wakeUpRun() for targeting deployments with namespaced queue topics, and make healthCheck() respect its timeout when the stream read hangs.
• #2857 2c6ee61 @karthikscale3 - Add stream latency to OTEL spans

• #2873 4dce2ae @VaguelySerious - Cancel the v4 event frame stream when a reader stops early, so the response body's undici connection returns to the pool instead of leaking.
• #2790 145835b @NathanColosimo - Centralize workflow event type classifiers and event-data payload field helpers.

• #2864 8b3a358 @mitul-s - Remove unused flex-1 from attribute copy-value rows so values hug their content.
• #2790 145835b @NathanColosimo - Centralize workflow event type classifiers and event-data payload field helpers.
• #2837 392d347 @mitul-s - Anchor the trace viewer shortcut helper to the timeline's left edge and hide it below a container-query width instead of a viewport breakpoint.

@workflow/[email protected]

• #2853 df7e71d @NathanColosimo - Use the Windows-safe generated-file writer for step registration output.
• #1947 25b1509 @VaguelySerious - Externalize the optional @opentelemetry/api peer in the Rollup/Vite framework builds (SvelteKit, Nitro, Nuxt, Astro, Vite) only when it isn't installed, so a build no longer fails with "failed to resolve import '@opentelemetry/api'". When the peer is present it is bundled/resolved as before, so tracing keeps working — including in self-contained outputs like Nitro's .output/server.

• #2833 3f69666 @VaguelySerious - Report time-to-first-step and step-to-step overhead latency telemetry on step completion events.
• #2833 3f69666 @VaguelySerious - experimental_setAttributes now resolves via an in-process replay instead of a queue re-invocation, removing a delivery round-trip before subsequent steps.
• #2840 712ed61 @VaguelySerious - Add an optional reason to run cancellation (run.cancel({ cancelReason })), recorded on the cancellation event and shown in the run detail view.

@workflow/[email protected]

• #2830 79a9813 @AndrewBarba - Fix hook operations scaling with total event history: hook creation, hook cache rebuilds, and token lookups now use durable per-token/per-hookId indexes instead of scanning the entire global event log, and run-termination hook cleanup uses per-run markers instead of reading every live hook. Directory listings read files concurrently, runs.list defaults to a page size of 200, and compiled filename regexes are reused.

@workflow/[email protected]

• #2817 d6defd4 @mitul-s - Add an optional getModuleSourceUrl resolver to the trace viewer sidebar data so hosts can render the Module row in the span detail panel as a link to the module's source (e.g. the deployment source view on vercel.com).
• #2827 0459ffc @mitul-s - Fix middle truncation on detail panel
• #2832 3679833 @mitul-s - Use solid instead of alpha borders for trace viewer event-list dividers.
• #2840 712ed61 @VaguelySerious - Add an optional reason to run cancellation (run.cancel({ cancelReason })), recorded on the cancellation event and shown in the run detail view.
• #2838 f2f4b9d @mitul-s - Make the trace event-list/timeline split-pane divider drag match the span detail panel: wider hit target, hover/focus/drag highlight, double-click reset, and keyboard/ARIA resize.
• #2826 68ad966 @mitul-s - Keep the Input/Output sections of the span attribute panel open after decrypting run data.
• #2835 cfdb86d @mitul-s - Smooth the new trace viewer's click-to-focus zoom with a stronger ease-in-out curve.

@workflow/[email protected]

#2779 7637196 @VaguelySerious - Fix createHook() conflicting with the run's own disposed hook when a token is reused after dispose() within the same run
#2732 239031a @NathanColosimo - Respect framework base paths when routing workflow traffic and expose health checks on generated Next.js workflow routes.
#2807 e7e5a0e @VaguelySerious - Steps that receive an AbortSignal argument no longer pay a per-step queue round-trip: the real-time abort-stream reader opened for such a step is now released when the step finishes, so the step can complete inline instead of reporting pending work on every invocation.
#2752 0f557d5 @ijjk - Statically inject the configured world package into host bundles instead of selecting worlds dynamically at runtime.
#2468 49a50e8 @NathanColosimo - Standardize first-party World packages on createWorld(), support relative target World modules consistently, and align the Postgres World DATABASE_URL fallback with bootstrap.

@workflow/[email protected]

#2648 17d4ce2 @karthikscale3 - inspect list views (runs, steps, events, sleeps) now read from the optional world.analytics namespace when the backend provides one, falling back to the runtime storage APIs otherwise. Hook listing stays on the runtime storage APIs (the analytics rows omit ownerId and the hook token). Payload/detail views are unchanged. The --withData flag is deprecated for list views; use workflow inspect <resource> <id> to view payloads for a single resource.
#2806 54f46f9 @karthikscale3 - Ensure the CLI can resolve community world packages if not statically injected. Fixes "Unsupported workflow backend" error.
#2812 fe327e6 @karthikscale3 - Add --since/--until to workflow inspect runs; workflow start and bulk workflow cancel name lookups now search past the backend's default 24h window.

@workflow/[email protected]

#2812 fe327e6 @karthikscale3 - Support startTime/endTime on world.analytics.runs.list to bound the listing window.

@workflow/[email protected]

#2808 c1d29f1 @VaguelySerious - Fix a stalled hook token claim release deleting the next claimant's live claim
#2808 c1d29f1 @VaguelySerious - Fix a resumeHook racing hook.dispose() being recorded after the disposal, which corrupted the receiving run's replay
#2779 7637196 @VaguelySerious - Fix hook token claims of disposed hooks and finished runs not being released to the next claimant
#2807 e7e5a0e @VaguelySerious - Shard stream chunks into a directory per stream so a tail reader's poll no longer lists every chunk in the world on each tick, and reliably release its emitter listeners and poll timer when the reader is cancelled. Note: stream chunks are now stored at streams/chunks/<streamName>/; chunk files written to the old flat layout by an earlier version are not read back (an acceptable tradeoff for local dev data, and stale flat files are left in place rather than cleaned up).
#2732 239031a @NathanColosimo - Respect framework base paths when routing workflow traffic and expose health checks on generated Next.js workflow routes.
#2752 0f557d5 @ijjk - Statically inject the configured world package into host bundles instead of selecting worlds dynamically at runtime.

@workflow/[email protected]

#2647 1518c48 @karthikscale3 - The runs, steps, and events observability list views now read from the metadata-only world.analytics namespace when the configured backend provides one, and fall back to the runtime storage APIs otherwise. Event payloads are still loaded lazily per event on the runtime path. Hooks listing, detail views, payload resolution, streams, and mutations are unchanged.
#2652 ae51f45 @karthikscale3 - The hooks list now reads from the metadata-only world.analytics namespace when the backend provides one (falling back to the runtime storage APIs otherwise). A hook's secret token is no longer included in list rows — it is fetched one hook at a time via world.hooks.get only when the user copies the token or resumes the hook.
#2804 cdfac39 @karthikscale3 - Fix workflow web for local and postgres backends after static world-target injection. The web server now constructs the local world directly and resolves other world packages from the inspected project, instead of calling the createWorld() static-injection stub (which throws when no build plugin aliased it).
#2812 fe327e6 @karthikscale3 - Runs list: infinite scroll with SWR-cached pages (tab switches no longer refetch), a plan-aware time-window picker (default 24h), and status filtering without requiring a workflow filter.

@workflow/[email protected]

#2800 caac565 @mitul-s - Add a minimap to the new trace viewer: a full-run span density strip with a glass viewport brush supporting pan, edge-resize, click-to-jump, drag-to-select zoom, wheel gestures, and keyboard panning.
#2775 8a76688 @mitul-s - Fix duplicate sub-second tick labels on the trace viewer timeline ruler, and trim trailing zeros from precise duration labels ("2.00s" → "2s").

#2718 cc7f076 @VaguelySerious - Make runtime tuning constants (timeouts, retry counts, stream buffering/reconnect) configurable via WORKFLOW_* environment variables, and forward WORKFLOW_TEST_LIMIT_OVERRIDES to the backend as a request header so a deployment can tighten server-side limits for testing.

#2665 5a23159 @NathanColosimo - Reduce e2e timing and polling flakes.

#2678 f6772d9 @ijjk - Speed up Next.js workflow dev rebuilds, ignore commented imports during HMR discovery, and avoid Turbopack resolving custom-world dynamic imports.

@workflow/[email protected]

#2234 f76377b @karthikscale3 - Add an optional metadata-only world.analytics namespace for observability reads (runs, steps, events, hooks, waits). Implemented by @workflow/world-vercel; payload-bearing fields remain on the canonical runtime storage APIs.

• #1853 f2ad726 @TooTallNate - Add wire-level framing for byte streams (type: 'bytes') so consumers can identify chunk boundaries — a prerequisite for transparent auto-reconnect.
• #2397 20a6d73 @pranaygp - start({ deploymentId: 'latest' }) is now a no-op in Worlds that don't support atomic deployments (local dev, Postgres) instead of throwing — it logs a warning and targets the current deployment, so workflows that use 'latest' on Vercel still run locally.
• #2473 015452a @pranaygp - Drain consecutively consumable replay events in a single synchronous pass instead of one process.nextTick per event, removing O(N) macrotask hops from replay.
• #2768 d0e4191 @VaguelySerious - Correct the byte-stream framing capability cutoff so framed byte streams are never written to deployments that cannot decode them
• #2522 5a4c5f @VaguelySerious - Cache the local dev server port per process so workflow replays no longer re-run OS port discovery (which spawns lsof on macOS, ~60ms) on every replay.
• #2511 db8a2c4 @VaguelySerious - Emit workflowName on per-step events (step_created, step_completed) so Worlds can access it without additional queries
• #2471 170ea96 @pranaygp - Cache the compiled workflow-bundle vm.Script per process so replays reuse the compiled bundle instead of re-parsing it on every iteration.
• #2472 0a5e2aa @pranaygp - Memoize hydrated step return values across inline replay iterations, turning the per-invocation step-result decrypt+parse cost from O(N²) to O(N) for sequential workflows. Only primitive results are cached, so deterministic replay is preserved.
• #2565 a4dd59b @ijjk - Collapse default workflow build output to a single completion summary and move detailed progress logs behind DEBUG=workflow:build.

• #2747 6dbe2de @NathanColosimo - Keep local hooks reachable after a crash or restart by rebuilding lost hook cache files from committed hook creation events, preventing active hook tokens from being reused.
