Minor Changes

  • #14602 7692a61 Thanks @edmundhung! - Add unsafeEvictDurableObject() for targeted Durable Object eviction

    This lets users verify how a Durable Object recovers after its instance is torn down.

  • #14602 7692a61 Thanks @edmundhung! - Allow listDurableObjectIds() to accept Durable Object class names as well as binding names.

Patch Changes

  • #14627 ed33326 Thanks @tpmmorris! - Add convenient logging for worker emails in the project directory. In addition to the system's temp directory, logs for emails sent by workers are also written to a local temp directory defined by the calling process, e.g for an simple text email sent via Wrangler this is .wrangler/tmp/email/<session>/email-text/<message-uuid>.txt (and related files) in the project root. Callers of Miniflare can control this location via the new defaultProjectTmpPath option, which Wrangler and Vite plugin now set automatically.

  • #14642 018574b Thanks @dependabot! - Update dependencies of "miniflare", "wrangler"
