Device firmware stays on the device, and a one-command installer.
- Releases no longer include LineageOS's vendor files (the Wi-Fi and Bluetooth drivers and firmware). They belong to Amazon and the chip makers, so each Show keeps its own copy: on the first boot of this version it is copied from the previous slot into the slot store, and every later update reuses it. Nothing changes in how the Show works.
- New: tools/install-show.ps1 installs TECHO5 on a Show running LineageOS in one command, on Windows, Linux or macOS (PowerShell 7), with nothing to build. It keeps the Show's own vendor files before erasing LineageOS. See docs/install.md.
- Every Echo's install is now step by step in docs/getting-started.md, built on @proffalken's write-up of installing on Linux. Thank you!
- Releases carry SHA256SUMS; build scripts have no machine-specific paths (docs/building.md, tools/fetch-inputs.ps1).
The boot image is unchanged from v0.4.0.
