# Changelog

## v0.5.0

Backwards incompatible change: The WiFi access point property (e.g.,
["interfaces", "wlan0", "access_points"]) is now a simple list of access point
structs. It was formerly a map and code using this property will need to be
updated.

## v0.4.1

* Improvements
  * Support run-time configuration of regulatory domain
  * Error message improvement if build system is missing pkg-config

## v0.4.0

Build note: The fix to support AP scanning when in AP-mode (see below) required
pulling in libnl-3. All official Nerves systems have it installed since it is
required by the wpa_supplicant. If you're doing host builds on Linux, you'll
need to run `apt install libnl-genl-3-dev`.

* New features
  * Report IP addresses in the interface properties. It's now possible to listen
    for IP address changes on interfaces. IPv4 and IPv6 addresses are reported.
  * Support scanning for WiFi networks when an WiFi module is in AP mode. This
    lets you make WiFi configuration wizards. See the vintage_net_wizard
    project.
  * Add interface MAC addresses to the interface properties

* Bug fixes
  * Some WiFi adapters didn't work in AP mode since their drivers didn't support
    the P2P interface. Raspberry Pis all support the P2P interface, but some USB
    WiFi dongles do not. The wpa_supplicant interface code was updated to use
    fallback to the non-P2P interface in AP mode if it wasn't available.

## v0.3.1

* New features
  * Add null persistence implementation for devices migrating from Nerves
    Network that already have a persistence strategy in place

## v0.3.0

* New features
  * Support the `busybox` hex.pm package to bring in networking support if not
    present in the Nerves system image. This enables use with the minimal
    official Nerves images.
  * Add Unix domain socket interface to the `wpa_supplicant`. This enables
    much faster scanning of WiFi networks and other things like collecting
    attached clients when in AP-mode and pinging the supplicant to make sure
    it's running.
  * Log output of commandline-run applications so that error messages don't get
    lost.
  * Provide utilities for reporting WiFi signal strength as a percent to end
    users.

* Bug fixes
  * Support scanning WiFi access points with Unicode names (emoji, etc. in their
    SSIDs)
  * Allow internet connectivity pings to be missed 3 times in a row before
    deciding that the internet isn't reachable. This avoids transients due to
    the random dropped packet.
  * Reduce externally visible transients due to internal GenServers crashing and
    restarting - also addressed the crashes
  * Support configure while configuring - let's you cancel a configuration that
    takes a long time to apply and apply a new one

## v0.2.4

* New features
  * Listen for interface additions and physical layer notifications so that
    routing and status updates can be made much more quickly
  * Add `lower_up` to the interface properties

## v0.2.3

* Bug fixes
  * This release fixes supervision issues so that internal VintageNet crashes
    can be recovered
  * `VintageNet.get_configuration/1` works now
  * `"available_interfaces"` is updated again

## v0.2.2

* Bug fixes
  * Fix local LAN routing

## v0.2.1

* New features
  * Expose summary status of whether the whole device is
    disconnected, LAN-connected, or Internet-connected

## v0.2.0

* New features
  * Support WiFi AP mode - see README.md for example

* Bug fixes
  * Alway update local routes before default routes to avoid getting errors when
    Linux detects an unroutable table entry

## v0.1.0

Initial release to hex.
