| Feature | Why It Matters |
|---------|----------------|
| Improved CLI ergonomics – New --dry-run flag that simulates a deployment without touching devices. |
| Enhanced logging – JSON‑structured logs (compatible with ELK/Graylog) are now emitted by default. |
| Patch‑level security fix – Addresses CVE‑2025‑1234 (an input‑validation flaw in the device‑filter module). |
| Dependency‑graph visualizer – Generates a GraphViz .dot file showing which devices depend on which firmware components. |
| Cross‑platform binaries – Official packages for Windows 10/11 (x64), macOS 13+, and major Linux distros (Ubuntu 22.04, Debian 12, Fedora 38). |
| Documentation refresh – The mdkarm‑help command now displays context‑sensitive help for sub‑commands introduced in v5.2.x. |
These changes make the tool a little easier to adopt in mixed‑OS environments and tighten its security posture—a key consideration for any production deployment pipeline.
