v1.9.4-time-skipping

Temporal CLI v1.9.4-time-skipping

This release lets you test Workflow and Schedule time skipping with temporal server start-dev. It embeds unreleased Temporal Server and Go SDK builds and adds an --enable-time-skipping flag for local testing. Use the stable CLI unless you need this feature.

Embedded OSS Server

The Server is pinned to a main commit, and the SDK is pinned to a feature commit, rather than release tags.

Dev server dynamic config

Start the dev server with Workflow and Schedule time skipping enabled for all Namespaces:

temporal server start-dev \
    --namespace timeskipping-test \
    --enable-time-skipping

Schedule time skipping requires CHASM Schedules, so this flag also enables CHASM creation for new Schedules.

Key	With --enable-time-skipping	Server default
system.workflowTimeSkippingEnabled	true	false
system.chasmSchedulerTimeSkippingEnabled	true	false
history.enableCHASMSchedulerCreation	true	false
history.chasmSchedulerCreationRolloutPercent	100	0
history.enableCHASMSchedulerRouting	true	true
