• Changes
  • Replace screensaver implementation with Myelin. Myelin is a library that uses WPE WebKit’s web extension to add functionality to web pages. This simplifies the screensaver and also makes it work when browsing the general internet. (Thanks to @tomfarm for this library)
  • Update Nerves systems to Erlang 29.0.4
    

This release include dependency updates and a fix for RPi5 WPA3 SAE users.

  • Update Nerves systems to Erlang 29.0.4
    

This release include dependency updates and a fix for RPi5 WPA3 SAE users.

• defensively support HTTP/1.1 in bin/latest-stable ( 0b60cce )
• install works if $USER is not set ( #20 ) ( 2facefd )
• minor issues in post-install instructions ( 0dfe5de )
• properly trap errors during install ( 4f65021 )
• respect ASDF_CONCURRENCY if set ( b7be081 )

• Improvements
  • Improve visibility of the UUID nickname and errors when running mix upload

This release adds support for the Nerves 2.x mix integration. At the time of this release, Nerves 2.0.0 has not been released so mix nerves.new continues to create Nerves 1.x projects.

There are no plans to drop support for the Nerves 1.x mix integration since it’s easy to support both.

This release primarily includes internal code cleanup and more unit tests.

• Changes
  • mix nerves.new <project> --target <target> supports some not-yet-official Nerves targets. For example, mix nerves.new my_project --target trellis adds support for the Nerves Starter Kit. Run mix nerves.new my_project --target list to get a list of known targets.
  • Documentation and error message updates

• Changes
  • Fix Elixir 1.20 warnings
  • Drop Elixir 1.14 support since 1.20 fixes don’t compile there

• New features

  • Transfers greater than the max transfer size are supported. They’re automatically segmented in the NIF. While you can still segment in Elixir, allowing Circuits.SPI to do it is faster. You’ll still see a short pause between segments and the CS line will toggle between transfers if you’re using it.
  • Add SPI.read/2 and SPI.write/2 to avoid a buffer allocation either for the written data or the read data when it’s unconditionally thrown away. This is a small performance improvement when using devices requiring large transfers like displays.
    

• Changes

  • Add more info to Circuits.SPI.info/0
  • Various documentation improvements throughout

This release adds a mechanism for per-device customizations to cookbook configurations. For example, to apply the sae_pwe fix for WPA3 support on Raspberry Pi 5.

• Changes
  • Add cookbook_extras for device-specific cookbook config customizations
    

• Changes
  • Add sae_pwe wpa_supplicant option to fix WPA3 support on Broadcom WiFi modules like those on the Raspberry Pi’s. See https://github.com/nerves-networking/vintage_net_wifi/pull/315 . (@BryanLeong)
  • Support setting the WiFi MAC address similar to VintageNetEthernet. (@gordoneliel)

This release adds support for using Apple Container as an alternative to Docker for building Nerves systems on macOS. It’s used automatically if available. (@tomfarm)

Reports vary but this seems on par with UTM speeds for building Nerves systems which has historically beaten Docker by a wide margin.

• Changes
  • Add mix nerves.artifact.details --copy-fwup-conf <path> helper
  • Support mix nerves.artifact.details without a MIX_TARGET

This is a larger than usual feature update. While it is unexpected to be backwards incompatible, please review the compatibility notes below just in case.

• New features

  • Added Circuits.GPIO.subscribe/2 as an alternative to set_interrupts/3. This function simplifies matching of GPIO change notifications and is extensible. It is required for listening to changes for multi-GPIO handles.
  • Support opening multiple GPIOs using one handle. This allows backends to read and write a set of GPIOs atomically. It’s supported on Linux for GPIOs in the same hardware bank.
  • Support passing GPIO handles to Circuits.GPIO.status/1
  • Added Circuits.GPIO.force_close/1 to close open handles without knowing the handle. This is especially useful when working at the IEx prompt or Livebook and you’ve lost the handle. If the handle is used, it will raise an exception.
  • Added an on_busy: :take_over option to Circuits.GPIO.open/3 to automatically close any other open handles for the specified GPIO or GPIOs. This is not the default. It can be used in GenServer :init callbacks to avoid a race with the Erlang GC for cleaning up handles from a previous failure.
    

• Backwards incompatible changes

  • Circuits.GPIO.write/2 no longer treats all non-zero values as 1. Even though the typespec for write/2 restricted values to 0 and 1, the implementation was forgiving. This is no longer the case.
  • Previously unknown errno values were reported as {:errno, n}. They’re now reported as their lowercase errno names using Erlang’s built-in errno conversion.

• Changes
  • Support passing initial commands to RingLogger.viewer. E.g., Ringlogger.viewer("a application1")

• Remove unintentinoal requirement on the cell tower reporting a circuit switched connection for reporting Internet connectivity. Thanks to @jollyjerr for reporting that some cell towers were no longer supporting this and that the check should be removed.
• Set network interface MTU based on report from the modem. Thanks to @@joserp93.
• Drop support for Elixir 1.14
