Zerostack v1.3.4 released – Lightweight Unix-like coding agent

Zerostack v1.3.4 has been released, introducing a new permission mode system with five levels — Restrictive, ReadOnly, Guarded, Standard, and YOLO — along with an experimental alternative edit tool and cross-platform sandboxing via zerobox.
