# Changelog



## v0.1.0



Initial release, extracted from the Universal Proxy Nerves application

(hardware-validated on a Raspberry Pi 3 B+ against the Home Assistant

companion app).



- Improv-over-BLE protocol: submit Wi-Fi (`0x01`), identify (`0x02`),

  device info (`0x03`), scan networks (`0x04`); capabilities byte derived

  from configuration.

- BlueZ-over-D-Bus GATT server + LE advertisement (via the `bluez`

  library), mounted in `Bluez`'s `extra_children:` slot.

- Advertisement ServiceData in the spec's 6-byte/16-bit-key form — fits

  the 31-byte legacy advertising budget of BT 4.x controllers.

- Session security: no-connectivity arm gate (once per boot), idle

  timeout with meaningful-advance-only resets, absolute session cap,

  connect timeout with in-session retry.

- Optional VintageNet Wi-Fi backend (`Improv.Wifi`) and optional

  Phoenix.PubSub status broadcasts.
