v1.6.0

Nerves 1.6.0 adds support for Elixir 1.10.

As part of the update to Elixir 1.10, it became more difficult to support old
Elixir and Erlang versions. Therefore, Nerves 1.6.0 requires at least Elixir
v1.7.0 and Erlang/OTP 21. If your project requires an older version of Elixir or
Erlang/OTP you can pin the version of nerves to an older version.

For example, set your nerves dependency in your mix.exs to:

{:nerves, "~> 1.5.0", runtime: false},

• Enhancements
  • Add support for aarch64 host architecture.
  • Add mix firmware.metadata for listing firmware metadata values.

v1.5.4

• Enhancements

  • Add mix firmware.unpack to unpack generated .fw files. This is useful
    to inspect the contents of the target root filesystem and other .fw info
    on the host.
  • Update mix burn to accept the path to a .fw file with --firmware | -i.

• Bug fixes

  • Invoke mix firmware when calling mix firmware.image. This matches the
    behavior of mix firmware.burn.
  • Fix issue with artifact base_dir expansion. This fixes an issue where mix
    would attempt to resolve the nerves dependency artifacts even though they
    have already been downloaded.
  • Always generate erlinit.config, even if there are no config override in
    mix config. This fixes an issue where removing overrides from mix config
    would not update the erlinit.config.

v1.5.3

• Bug fixes
  • Fix various erlinit option parsing/formatting issues.

v1.5.2

• Enhancements

  • erlinit.config options can be overridden using the application config now.
    For example, in your config.exs you can now add:

    config :nerves, :erlinit,
      ctty: "ttyAMA0"

  • Nerves tooling now supports setting the SOURCE_DATE_EPOCH environment
    variable for reproducible builds during compilation via :source_date_epoch
    in your application config. This removes timestamp differences between
    builds. See reproducible-builds.org for more information.

  • Windows Subsystem for Linux improvements

  • Support XDG_DATA_HOME. If XDG_DATA_HOME is set, Nerves will now store its
    data under that directory.

• Bug fixes

  • Do not require sudo on mix burn if already privileged.
  • Keep all boot scripts. Previously, extraneous boot scripts from the OTP
    release process were removed. Keeping them makes it possible to start
    Erlang slave nodes and support use cases where triggers at device boot
    time launch different scripts.

v1.5.1

• Bug fixes
  • Update compiler check on mix firmware to use the system OTP version
    when recommending an Elixir install.
  • Check if using Distillery when calling mix nerves.release.init.
    This is no longer required for Elixir 1.9+ releases.

v1.5.0

Updating to Nerves v1.5.0 requires modifications to your project
See the project update guide to learn how to migrate your project.

• Enhancements

  • Added support for Elixir 1.9+ releases.

• Bug fixes

  • Do not include empty priv directories when constructing rootfs
    priorities.

v1.4.5

• Enhancements

  • Updated docs.

• Bug fixes

  • Updated the requirement for distillery to ~> 2.0.12. This fixes an issue
    where nerves would downgrade to 1.4.0 when updating shoehorn.
  • Empty priv directories are not added to the squashfs sort ordering list.

v1.4.4

• Bug fixes
  • This improves the path fix in v1.4.3 (see
    #389) to cover the local
    build runner as well.

v1.4.3

• Bug fixes

  • Raise an exception if the artifact cache fails to create a directory

  • Fixes ArgumentError when using OTP >= 21.3.0 and calling mix nerves.system.shell

  • Fixes issue with mix nerves.system.shell using asdf >= 0.7.0 where the
    path would contain :: and Buildroot would raise the error:

    You seem to have the current working directory in your
    PATH environment variable. This doesn't work.
    support/dependencies/dependencies.mk:21: recipe for target 'dependencies' failed
    

v1.4.2

• Improvements
  • Generate rootfs.priorities file. This is used internally when constructing
    the squashfs filesystem to arrange the contents in the order the files are
    loaded at runtime which improves boot performance.
