Full Changelog: v1.0.0...v1.0.1

Open Freematics Emulator 1.0.0

First public release.

Features

• Control a Freematics OBD-II Emulator MK2 over USB: protocol, PIDs, trouble codes, VIN and
  supply voltage, from a desktop app or a browser.
• Instrument cluster: drag a gauge or type a value to set it, with warning lamps and the scan
  tool's read-back on the same dial.
• Scan tool screen: read every setting back through an ELM327 adapter (Bluetooth, USB or Wi-Fi)
  plugged into the emulator, as a real scan tool would.
• Driving-scenario presets, named trouble codes, and firmware-aware locks for what the MK2's
  firmware can't do.
• Update the MK2's firmware from the app with the official Freematics images, on any OS.
• Simulated MK2 and adapter, so the app runs without hardware.
• Installers for macOS (signed and notarized), Windows and Linux, npx open-freematics-emulator,
  and a Homebrew cask.

Bug Fixes

• server: only accept requests from the app's own page.
• desktop: give the Mac app a valid signature.
