• #2164 0606949 @mitul-s - Add a loading skeleton to the new trace viewer that matches the real layout's dimensions, and start with the detail panel closed instead of pre-selecting the first span. The skeleton is also exported as TraceViewerSkeleton for consumers that need to render it standalone.

workflow@4.2.6

@workflow/core@4.2.6

• #2179 e256858 @pranaygp - Harden runtime event pagination against rejected, repeated, or overlapping cursor responses.
• #2171 38c67a7 @TooTallNate - Fix CorruptedEventLogError on replay when a workflow races a hook read against a sleep() (e.g. Promise.race([hook, sleep])). Branch-deciding deliveries (buffered hook payloads and wait completions) are now handed to the workflow in strict event-log order — anchored on event position rather than on microtask-resolution timing — so the committed branch wins the race deterministically, independent of decryption/hydration time or Promise.race argument order.
• #2156 ebfeede @VaguelySerious - Harden workflow error stack remapping for large inline sourcemaps.
• #2142 3113738 @pranaygp - Prevent failed stream writes from surfacing as unhandled rejections and include request correlation details in stream errors.

@workflow/world@4.1.3

• #1979 8ab6c4f @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.

@workflow/world-local@4.1.3

• #2142 3113738 @pranaygp - Prevent failed stream writes from surfacing as unhandled rejections and include request correlation details in stream errors.

@workflow/web@4.1.7

• #2107 e313c66 @karthikscale3 - Allow lookup of exact step ID (step_), wait ID (wait_), hook ID (hook_), or event ID (evnt_) in the event list UI.

• #2041 799cc09 @mitul-s - Update zoom factor on the trace viewer timeline
• #2143 e8e5292 @mitul-s - Fix Button hover, focus, and corner radius to match Geist. The dark-mode hover no longer relies on an unregistered Tailwind variant (it previously turned the inverted button's background dark/transparent depending on the consumer), the focus-visible ring is now rendered, and the xs size uses Geist's 4px tiny radius. Styles are written to work under both Tailwind v3 and v4.

• #2087 a490f58 @VaguelySerious - Fix the "Queued for" duration shown in the events list for retried steps. It now measures from step_created to the first step_started instead of the last, so the displayed value reflects actual queue time rather than queue time plus all retry waits.

Workflow discovery is now deferred until files are requested instead of scanning eagerly at startup on Next.js versions that support deferred entries (>= 16.2.0-canary.48). Older versions automatically fall back to eager discovery. Pass workflows: { lazyDiscovery: false } to opt back into eager discovery on supported Next.js versions.
