@workflow/world

4.2.1

Patch Changes

• #2295 f9119d4 Thanks @TooTallNate! - Fix world-local and world-postgres turning duplicate processing of the same hook_created (same runId, hookId, and token) into a self-conflict; both worlds now treat same-entity duplicates as idempotent (matching step_created), and recover crash-orphaned token claims (world-local) and hook rows (world-postgres) by completing the partial write instead of incorrectly suppressing it.

• #2511 db8a2c4 Thanks @VaguelySerious! - Emit workflowName on per-step events (step_created, step_completed) so Worlds can access it without additional queries

• #2580 9fba14e Thanks @karthikscale3! - Send optional client-side event occurrence timestamps through world event creation.

• #2414 2a688f0 Thanks @github-actions! - New internal API format: separately encode event metadata from user payloads. Eliminates the need for calling separate endpoints for ref resolution, which improves performance especially on longer runs.

• #2747 6dbe2de Thanks @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.

• #2622 87d213c Thanks @karthikscale3! - Declare Zod as a runtime dependency so exported schemas are built with the package's own Zod version instead of the consuming application's peer.

4.2.0

Minor Changes

• #2305 9c667e0 Thanks @willsather! - Add an optional namespace parameter that scopes queue topic prefixes to __{namespace}_wkf_workflow_*. This allows configuring multiple frameworks in the same deployment without queue topic collision.

4.1.5

Patch Changes

• #2012 326d93a Thanks @pranaygp! - Expose the active run ID on hook token conflict errors.

• #1799 eca3b51 Thanks @TooTallNate! - Use inline sourcemaps for all workspace packages; published packages no longer ship external .js.map files.

4.1.4

Patch Changes

• #2191 5a0ce9a Thanks @pranaygp! - Fix forwarded writable stream encryption when child workflows execute on a newer deployment than their parent.

• #2208 5fd7d9c Thanks @pranaygp! - Retry transient workflow replay divergence before classifying repeated divergence as a corrupted event log.

4.1.3

Patch Changes

• #1979 8ab6c4f Thanks @adamiBs! - Make run.input and step.input .optional() on the World snapshot schemas so consumers no longer fail validation when the service externalizes payloads as RemoteRef blobs.

4.1.2

Patch Changes

• #2029 a434184 Thanks @pranaygp! - Refresh workflow events after completing elapsed waits so concurrent hook events preserve deterministic replay order.

• #2046 8407c1e Thanks @pranaygp! - Report corrupted event logs with a distinct CorruptedEventLogError type and CORRUPTED_EVENT_LOG run error code.

• #1902 15e44b3 Thanks @ziyak97! - Fix compatibility with Zod 4.4.x in WorkflowRunSchema by marking output, error, and completedAt as .optional() on non-final / cancelled / completed / failed run states.

• #2030 c347509 Thanks @pranaygp! - Validate step, wait, and hook lifecycle events against replay ownership metadata.

4.1.1

Patch Changes

• 2ece7ba Thanks @VaguelySerious! - Fix community world E2E tests by adding specVersion to the World interface so start() uses the safe baseline (v2) for worlds that don't declare their supported version

4.1.0

Patch Changes

• #1640 8890b33 Thanks @VaguelySerious! - Stable release

4.1.0-beta.16

Patch Changes

• #1605 b30b0dc Thanks @VaguelySerious! - Use asymmetric ULID timestamp validation thresholds: 24h past, 5min future.

4.1.0-beta.15

Patch Changes

• #1569 a98f8de Thanks @VaguelySerious! - Combine initial run fetch, event fetch, and run_started event creation

• #1534 329cdb3 Thanks @VaguelySerious! - Re-enqueue active runs on world restart so inflight runs resume instead of getting stuck

4.1.0-beta.14

Patch Changes

• #1460 78f1b0e Thanks @VaguelySerious! - Support negative startIndex for streaming (e.g. -3 reads last 3 chunks)

• #1470 01bbe66 Thanks @VaguelySerious! - Add getStreamChunks() and getStreamInfo() to the Streamer interface, and getTailIndex() to the readable stream returned by run.getReadable(). WorkflowChatTransport now reads the x-workflow-stream-tail-index response header to resolve negative initialStartIndex values into absolute positions, fixing reconnection retries after a disconnect.

4.1.0-beta.13

Patch Changes

• #1396 2f0772d Thanks @karthikscale3! - Track Vercel request IDs (x-vercel-id) on all workflow events for correlating request logs with workflow executions

• #1364 94c14c7 Thanks @karthikscale3! - Strip only ref/payload fields from eventData when resolveData is 'none', preserving all other metadata

4.1.0-beta.12

Patch Changes

• #1317 825417a Thanks @TooTallNate! - Add optional resolveLatestDeploymentId() method to the World interface for resolving the most recent deployment ID for the current deployment's environment

Patch Changes

• #1287 d8daa2a Thanks @VaguelySerious! - Add world.events.get(runId, eventId) to the Storage interface for fetching a single event by ID.

4.1.0-beta.10

Patch Changes

• #1273 11dcb64 Thanks @VaguelySerious! - Locally validate run ID to be ULID when passed by user

4.1.0-beta.9

Patch Changes

• #1270 adfe8b6 Thanks @pranaygp! - Prevent hooks from being resumed via the public webhook endpoint by default. Add isWebhook option to createHook() to opt-in to public resumption. createWebhook() always sets isWebhook: true.

4.1.0-beta.8

Patch Changes

• #1217 e55c636 Thanks @pranaygp! - Upgrade dependencies across all packages

4.1.0-beta.7

Patch Changes

• #1188 b06e491 Thanks @ctgowrie! - New vercel queue client

4.1.0-beta.6

Patch Changes

• #956 b65bb07 Thanks @TooTallNate! - Overload getEncryptionKeyForRun interface: accept WorkflowRun (preferred) or runId string with optional opaque world-specific context for start()

4.1.0-beta.5

Patch Changes

• #979 6e72b29 Thanks @TooTallNate! - Add World.getEncryptionKeyForRun() and thread encryption key through serialization layer

• #1057 5e06a7c Thanks @pranaygp! - Materialize waits as entities to prevent duplicate wait_completed events

  • @workflow/core: Handle 409 conflict gracefully when creating wait_completed events, preventing crashes when multiple concurrent invocations race to complete the same wait
  • @workflow/world: Add Wait type, WaitSchema, and WaitStatusSchema exports; add optional wait field to EventResult
  • @workflow/world-local: Materialize wait entities on wait_created/wait_completed with duplicate detection; clean up waits on terminal run states
  • @workflow/world-postgres: Add workflow_waits table with wait_status enum; materialize wait entities with conditional writes for duplicate prevention; clean up waits on terminal run states

• #1081 5487983 Thanks @TooTallNate! - Add optional close() method to the World interface for releasing resources held by a World implementation

4.1.0-beta.4

Patch Changes

• #966 56f2221 Thanks @VaguelySerious! - Add 429 throttle retry handling and 500 server error retry with exponential backoff to the workflow and step runtimes

4.1.0-beta.3

Patch Changes

• #954 d9e9859 Thanks @TooTallNate! - Generate runId client-side in start() and simplify runId types

  The runId is now generated client-side using ULID before serialization, rather than waiting for the server response. This simplifies the Streamer interface and WorkflowServerWritableStream to accept string instead of string | Promise<string> for runId.

4.1.0-beta.2

Patch Changes

• #922 0ce46b9 Thanks @pranaygp! - Add support for custom headers in queue messages

• #867 c54ba21 Thanks @TooTallNate! - Add optional writeToStreamMulti function to the World interface

4.1.0-beta.1

Minor Changes

• #621 4966b72 Thanks @pranaygp! - Add backwards compatibility for runs created with different spec versions

  • Add RunNotSupportedError for runs requiring newer world versions
  • Add semver-based version comparison utilities
  • Legacy runs (< 4.1): route to legacy handlers
  • run_cancelled: skip event storage, directly update run
  • wait_completed: store event only (no entity mutation)
  • Unknown legacy events: throw error

• #621 4966b72 Thanks @pranaygp! - BREAKING: Storage interface is now read-only; all mutations go through events.create()

  • Remove cancel, pause, resume from runs
  • Remove create, update from runs, steps, hooks
  • Add run lifecycle events: run_created, run_started, run_completed, run_failed, run_cancelled
  • Add step_created event type
  • Remove fatal field from step_failed (terminal failure is now implicit)
  • Add step_retrying event with error info for retriable failures

Patch Changes

• #621 4966b72 Thanks @pranaygp! - Add hook_conflict event type for duplicate token detection

  • World returns hook_conflict event when hook_created uses an existing token
  • Add HOOK_CONFLICT error slug

• #853 1060f9d Thanks @TooTallNate! - BREAKING CHANGE: Change user input/output to be binary data (Uint8Array) at the World interface

  This is part of specVersion 2 changes where serialization of workflow and step data uses binary format instead of JSON arrays. This allows the workflow client to be fully responsible for the data serialization format and enables future enhancements such as encryption and compression without the World implementation needing to care about the underlying data representation.

• #621 4966b72 Thanks @pranaygp! - Remove deprecated workflow_completed, workflow_failed, and workflow_started events in favor of run_completed, run_failed, and run_started events.

• #621 4966b72 Thanks @pranaygp! - Add specVersion property to World interface

  • All worlds expose @workflow/world package version for protocol compatibility
  • Stored in run_created event and WorkflowRun schema
  • Displayed in observability UI
