Vnish Z15 Pro Firmware

Version 1.3.7

⌨️ We're pleased to announce the release of firmware v1.3.7, expanding our hardware ecosystem beyond the SHA-256 and Scrypt algorithms! In this release, we officially add support for the Antminer Z15 Pro (Equihash / ZEC algorithm).

⚙️ Key features for the Z15 Pro:
Manual frequency and voltage tuning: Get precise, detailed control over your hash boards with manual frequency and voltage adjustment, available right after installation.

Important note: To install or update the firmware on your hardware, make sure you are using Hashcore Toolkit version v1.7.5 or higher.

Version 1.3.6

⚙️ This one's a big deal for CV board users
Automatic Startup on CVitek Control Boards: Enjoy full, seamless automation on CVitek (CV) control boards without needing utilities like Hashcore Toolkit or Phoenix service. The firmware automatically initializes and persists across all reboots.

🔧 Bug Fixes & Refinements
CV Control Board Cleanup: Fixed the log cleanup routine when uninstalling firmware on CVitek (CV) control boards.

Version 1.2.6
