Changelog since v1.0.4

v1.0.5

• Fixed: Buzzer not sounding on nights with good Wi-Fi.
  When Wi-Fi connected and the clock synced successfully, the audio
  codec (the chip that drives the speaker) was never initialised — it
  was only being set up in the error/fallback code paths. This meant
  the push notification would arrive on your phone, but the device's
  built-in buzzer would stay silent even if you didn't acknowledge the
  alert. The codec is now initialised at boot regardless of whether
  Wi-Fi succeeds, so the buzzer is always ready.
