The noise reduction fix, and one TECHO5 for the Show, the Dot and the Spot.
- Fixed: with noise reduction on, a long mute (an hour or more) left the microphones deaf until a restart. Digital silence no longer disturbs the noise estimate.
- "Go home" stops the music as well as closing the page on screen.
- "Stop" now pauses music rather than ending it, from Home Assistant and from the wake word followed by "stop"; a track left paused for 30 minutes ends.
- Phone: a contact list for screens (the phone_contacts action), and calls keep their audio on every path.
- Radio: Home Assistant favorites fall back to stations near home when there are none.
- Cameras: with no list set, every camera in Home Assistant.
- Faster screen updates: only the parts of the screen that changed are written.
- Releases are now signed; this version checks the signature on every update after it.
- New: docs/getting-started.md, every step from a stock Echo.
The boot image is unchanged from v0.2.10.
Root filesystem removed: it included LineageOS's vendor files (device drivers and firmware), which aren't ours to distribute. Install v0.4.1 or later instead: devices keep their own vendor files from then on.
