Minor Changes

  • #14489 e3f0cd6 Thanks @edmundhung! - Add listDurableObjectIds() to Miniflare

    Miniflare now exposes listDurableObjectIds() for listing persisted Durable Object instance IDs by binding name. The Vitest pool now uses this shared Miniflare API internally instead of duplicating Miniflare's storage listing logic.

  • #14465 2fedb1f Thanks @vaishnav-mk! - Add rollback support when terminating Workflow instances

    WorkflowInstance.terminate({ rollback: true }) now runs registered rollback handlers before marking a local Workflow instance as terminated. Wrangler also supports this via wrangler workflows instances terminate --rollback, including local mode.

    The rollback option is only sent for terminate operations and is rejected by the Local Explorer API for pause, resume, and restart actions.
