Full Changelog: v0.0.3...v0.0.4

Crema Nightly

Rolling development build — the latest commit on main.

Same app as stable (dev.maceiras.crema), release-signed — so Obtainium
updates it in place. Follow this train with Include prereleases enabled;
for stable only, leave that off (or use IzzyOnDroid / a tagged release).
Moving from a nightly back to stable is a downgrade, so it needs a manual
reinstall.

Crema 0.0.1

Initial release. Crema is an open-source (GPL-3.0) companion app for the
Decent Espresso DE1 — a clean-room reimplementation
of the DE1 tablet experience as a fast, type-safe web PWA, with a parallel native
Android app. Both shells share one sans-IO Rust core for the Bluetooth protocol,
shot state machine, and domain model.

Added

Brewing & machine control

• Live brew dashboard — real-time pressure / flow / temperature / weight
  telemetry, a multi-channel chart whose time axis auto-grows with the shot, a
  phase indicator, and shot-completion metrics (time, yield, ratio, peak pressure).
• Quick Controls — steam, hot water, and flush with configurable targets, plus
  auto-tare and stop-on-weight.
• Profile library — the 88 standard de1app profiles built in, plus create / edit
  custom multi-frame profiles and live-preview each profile's intended
  pressure/flow curve.
• Group-head controller (GHC) — surfaced read-only; Crema correctly defers to the
  firmware's group-head start gate rather than fighting it.

Data

• Shot history — every pour recorded locally with full telemetry curves, linked
  to beans and roasters, with multi-shot overlay comparison and round-trip
  community-v2 .shot.json import/export.
• Bean & roaster library — track bags, roast dates, and grinder settings, attach
  optional bean-bag photos, and retroactively rebind a shot to a bean with snapshot
  semantics.
• Maintenance tracking — water-filter, descale, and cleaning reminders with
  one-tap buttons that drive the DE1's built-in cycles.

Hardware

• DE1 over Bluetooth — connect, control, and stream telemetry via the DE1's
  public BLE GATT protocol, with the wire format verified against the de1app and
  reaprime reference implementations.
• Bluetooth scales — Bookoo Themis, Decent Scale, Acaia (Lunar / Pyxis / Pearl),
  Skale, Eureka Precisa, Hiroia Jimmy, Difluid, Felicita, Atomheart Eclair, Varia
  Aku, and Smartchef.

Sync & backup (all opt-in, local-first by default)

• Visualizer — OAuth 2.0 + PKCE sign-in and two-way sync of shots, beans, and
  roasters with last-write-wins conflict resolution.
• Google Drive backup & restore — whole-app backup (preferences, profiles, shot
  history, and the bean/roaster library including photos) to your own Drive,
  strictly user-initiated.

Platforms

• Web PWA — runs entirely in the browser, offline-capable, nothing to install;
  Bluetooth pairing needs a Chromium-based browser. Hosted at
  crema.maceiras.dev.
• Android — native Jetpack Compose app with dedicated tablet and phone layouts
  and background BLE, distributed via Google Play, IzzyOnDroid, and a nightly
  Obtainium train.
• Shared Rust core — protocol codecs, shot state machine, profile model, and sync
  logic compiled to WebAssembly (web) and exposed via UniFFI (Android), so both
  shells stay in lockstep.

Notes

• Crema is unofficial and not affiliated with Decent Espresso.
• This is an early release, built with heavy LLM-assisted development, and provided
  as is with no warranty — see the Terms.
  Take particular care with machine-control settings (mains voltage, calibration,
  firmware updates).
