Release notes — Nuwa+ app v0.6.20+ / Firmware 5.1.4.8

What's new

Ink Engine v0.6

We're introducing Ink Engine v0.6, the algorithm that generates your Digital Copy from raw pen strokes. This version brings better accuracy on multi-line notes and a closer, truer match to your actual handwriting.

New firmware: 5.1.4.8

This is our most stable firmware release yet. It includes a fix for a memory write bug that could corrupt stored notes, a fix for a stack overflow that could cause unexpected pen crashes mid-write, and improved memory handling overall, including a more reliable memory erase process. Battery performance has also been improved.

Rock-solid BLE connectivity

Bluetooth syncing is significantly more reliable across both platforms. Expect fewer dropped connections and smoother syncing between your pen and the app.

New modes

Two new modes give you more control over how your pen operates:

  • Auto-Sync — automatically sync notes in the background without thinking about it

  • Flicker Mode — a new camera filter setting, configurable from general settings

Small things worth mentioning

Tabbed pen settings, the new in-app support sheet, and the overhauled setup flow from recent updates are all included in this release.
