ergohaven/entropy v0.4.0 on GitHub

v0.4.0 - Public Beta

Added full M4CR0Pad firmware 4.0.6 display customization: standby images and animations, startup images, clocks and dates, 32×32 pictograms, macro and Tap Dance assignments, and synchronized host previews
Added an adaptive symbol typing trainer that follows the active layout and prioritizes characters with more errors
Added a Nix flake with declarative NixOS and Home Manager modules

Added GUI chords to Mod-Tap choices and readable labels for Layer Lock
Added a dedicated label for firmware auto-layer deactivation on key press
Kept Matrix Tester geometry below the header, honored active layout options, and decoded firmware rows consistently
Allowed Layer-Tap and Mod-Tap keys as Key Override and RMK Fork triggers while continuing to reject invalid trigger values
Added bounded, serialized HID ownership for background display updates across keyboard switches and reconnects

Restored wired QMK/Vial loading for legacy VIA responses and made unsupported compatibility probes fail fast
Restored update checks after transient GitHub API failures and kept the pinned Layout Indicator visible
Kept wired keyboards discoverable after unplugging and reconnecting them
Preserved M4CR0Pad clocks when switching Entropy to another Ergohaven keyboard over USB or Bluetooth
Kept pictogram saves on the active editor page, waited for firmware 4.0.6 flash commits, and prevented stale or failed transfers from corrupting confirmed state
Strengthened USB/Bluetooth device identity, HID owner fencing, reconnect drafts, secure Vial unlock handling, and shutdown ordering
