ReleasePort's take

Light signal

editorial:auto 1mo

ReleasePort Layer 1 version 2.0.57 introduces several bugfixes and new features across APIs, migrations, datasets, and CLI workflows.

Why it matters: The breaking change (id 46142) alters enum‑fix migration rollbacks for in‑place column changes—a critical factor when planning database schema updates.

Summary
