Changelog

All notable user-facing changes to NucleoOS. Format loosely follows Keep a Changelog. Versions match firmware/version/VERSION and the pushed git tag (vX.Y.Z).

[0.4.0] — 2026-09-24

Added

  • Native Game Gear emulation — a from-scratch VDP/PSG/mapper machine around a vendored, permissively-licensed Z80 core (MAME's Z80, used by every small SMS/GG project, is "freeware, non-commercial" and revocable — unusable here). SMS/zip ROMs, EEPROM saves, shares the Game Boy emulator's front-end. Passes zexall/zexdoc in full.
  • Native Settings, rebuilt — one root list with live value previews and a suggestion chip for things needing attention (clock never set, no network, battery low + bright screen), sectioned pages (Wi-Fi · Hotspot · Bluetooth · Display · Sound · ANIMA · Language · Date/time · Device · Reset) that adjust in place like a watch crown, type-to-search across every setting, confirm cards before destructive actions, and a real date/time editor.
  • The browser IS the firmware AI engine — ANIMA's offline (WASM) and on-device engines now share one implementation, so answers behave identically in the browser and on the Cardputer.
  • One learned memory, recalled everywhere — a fact you teach ANIMA is recalled the same way on-device, from the host harness, and from the browser.
  • Streaming replies + a real Stop in the ANIMA web app, one context per client, reader mode, opening apps straight from an answer, and honest "I don't know" instead of a guess.
  • Complete native Calendar — month grid, add/edit/delete, large touch-friendly type.
  • Alarm v2 — silent mode with a bounded trigger and auto re-arm, an always-dark screen, an SD event log, and ambient WAV recording while armed.
  • Update system overhaul — automatic rollback safety, a browser→SD bridge so the native boot dialog can show "update available" without the device ever calling GitHub over TLS, and the native install now runs in a fresh-heap boot so a big OTA can't wedge the device.
  • All-channel Wi-Fi scan for reliable joins on networks the old scan missed.

Changed

  • Model choice across every AI surface (chat, ANIMA, Atelier) is resolved live instead of pinned — a retired model is swapped automatically, with plain-language errors when a provider can't be reached.
  • ANIMA's reasoning got sharper: reminders parsed the way people actually phrase them, better weather/app-name/device-action recognition, fewer wrong follow-up answers, four specific wrong answers fixed after a 2026-09 accuracy audit.
  • Every native app's chrome (icons, accent colors) now reads from one shared THEME_* role table, so a theme change recolors the whole native shell live, launcher included.
  • /api/fs/list now streams instead of buffering, so very large SD folders no longer answer with a 503 out-of-memory.
  • Faster, lighter ANIMA boot: ~5 KB less static RAM used per boot, one fewer large stack copy.
  • Game Boy emulator: a more accurate core, Pokémon-size battery-backed save RAM, crash-safe save states, and a measured-speed counter.

Fixed

  • The ANIMA web app's "Context" inspector modal had a see-through background (an undefined CSS variable), so the chat underneath showed through it; the AI-key manager in Settings was mounted flush against its card with no padding. Both fixed.
  • The local dev/CI device simulator (tools/serve-shell.mjs) could spin into an unbounded mkdir+list loop on boot, starving every other request behind "device busy" — the mkdir handler now only announces a change when it actually created something, matching real firmware behaviour.
  • Esc in the Game Boy emulator rebooted the whole console instead of leaving the game.
  • Several native-app papercuts: TAB not reaching all fields in Notes/SSH/Beacon, data loss in Notes, broken SSH output, Calendar back-key handling, Wi-Fi setup and ADV-keyboard edge cases, a remaining flicker on the Wi-Fi tools and OTA screens.
  • Hardened the web API: auth, the online-proxy against SSRF, OTA, filesystem and WebSocket endpoints against a batch of real failure modes found in a security pass.
  • ANIMA web app: confirmation before a destructive agent action, no silent model download, and it no longer claims a device action happened when it didn't.
  • Reproducible icon bundle build (normalized embedded-SVG line endings).

Also in this release

  • The release pipeline itself: gated, provenance-signed (build attestations), and self-verifying — this is the first release built by it.

Earlier history: git log v0.3.0..v0.2.11 and further back for the full commit trail — this file starts tracking from 0.4.0 onward.
