Changelog

v1.11.2 - 2024-09-27

Nerves support is shifting to Elixir Forum - Nerves Forum! This will now be the preferred and primary source for gaining Nerves support and documentation has been adjusted to reflect this shift.

  • Set TERM from user terminal when running mix nerves.system.shell on MacOS. Fixes an issue where config menus were not rendering
  • Documentation updates and improvements
    • Add instructions for mise
    • Remove USB Gadget mode serial references since not on official platforms

v1.11.1 - 2024-08-05

  • Fix Docker builds for nerves_system_br v1.28.0 and later (see #997)
  • Documentation updates and improvements

v1.11.0 - 2024-07-05

This release includes support for Elixir 1.17 and is generally safe for most, but some setups may be broken and require small changes:

  • Minimum Elixir version is now 1.13

  • If using Elixir >= 1.17, vm.args.eex needs to be updated to use the run function -run elixir start_cli. Firmware builds will fail if vm.args.eex settings are incompatible with the current Elixir version to prevent unbootable images.

  • Bug Fix

    • Docker build runner changed to mount ~/.ssh instead of attempting to use ssh-agent which would run into issues compiling systems on MacOS

v1.10.5 - 2023-12-26

  • Improvements

    • Support Elixir 1.16
    • Add support for :gitea_releases and :gitea_api artifact sites

  • Bug Fix

    • Ensure a package is loaded before compile.nerves_package

v1.10.4 - 2023-09-13

  • Improvements

    • Adjust compilation error when nerves_bootstrap is missing

  • Bug Fix

    • Adjust mix nerves.system.shell for OTP 26
      • With OTP 26, this task cannot completely handle the shell and instead prints out the command to run manually for the same effect.

v1.10.3 - 2023-07-07

  • Improvements
    • Support Elixir 1.15 / OTP 26
    • Fix misleading %IO.Stream{} error when building firmware
    • Add validations for vm.args.eex during firmware build

v1.10.2 - 2023-04-11

  • Improvements
    • Change BuildRunners.Docker to use GitHub Container Registry by default

v1.10.1 - 2023-03-08

  • Improvements
    • Use GitHubAPI for public release artifacts for helpful reports on error
    • Allow castore: v1.0 to be used

v1.10.0 - 2023-03-03

This release removes the ability to specify an alternative JSON codec with :json_codec config option and defaults to using Jason. If set, everything will function as normal but you will see a compiler warning.

  • Bug fix
    • Prevent accidentally installing :nerves as an archive
    • Add default mksquashfs flags when none specified

v1.9.3 - 2023-02-11

  • Bug fix
    • Temporarily revert GitHub release update in v1.9.2. It produces an error on new projects when downloading artifacts. It's easily fixed by adding a jason, but a better fix will be coming.

v1.9.2 - 2023-02-05

  • Improvements

    • :github_api artifact site resolver was completely refactored
      • More contextual error messages
      • GITHUB_TOKEN and GH_TOKEN environment variables supported (They were previously ignored despite the error message suggesting them to be used)
      • :user option no longer required, but still supported (effectively ignored by GitHub if the token is supplied)
    • :github_release switched to use the same GitHub resolver as :github_api in order to have the same benefits
    • Remove duplicate artifact request with 64 byte checksum name

  • Bug Fix

    • mix firmware now places temporary build products in MIX_BUILD_PATH which prevents them from being stored in _build/ root and compiling different targets in different terminals. See #576
    • Check if supplied rootfs_overlays have incompatible directories. See nerves-project/nerves_system_br#495.

v1.9.1 - 2022-09-11

This is a patch release that fixes trivial tooling issues found when using Elixir 1.14 and Erlang 25.0.4. It's expected to be a safe update from v1.9.0.

v1.9.0 - 2022-08-23

This release removes warnings when using Elixir 1.14 rc releases since they appear to work fine.

  • Improvements
    • Added mix nerves.artifact.details to list information in Nerves system and toolchain projects. Thanks to @udoschneider for this feature.
    • Many documentation updates including version charts for Nerves systems. Thanks to @mnishiguchi.

v1.8.0 - 2022-05-11

This release requires Elixir 1.11.2 or later. It has no new features. This is the first batch of updates to improve our ability to maintain Nerves tooling long term now that we can remove old features and workaround.

  • Bug fix
    • Fix missing space in CFLAGS and CXXFLAGS. It would sometimes cause compiler warnings.

v1.7.16

  • Bug fix
    • Fix Erlang compiler check so that Erlang/OTP 24.3 does not trigger an error when building projects.

v1.7.15

  • Bug fix
    • Fix TARGET_GCC_FLAGS issue that inadvertently removed CFLAGS options on Nerves systems that used it.

v1.7.14

  • Improvements
    • Unset environment variables set by Erlang that can confuse some C/C++ libraries when building.
    • Add experimental support for TARGET_GCC_FLAGS for enabling CPU-specific features in NIFs and ports via Nerves package definitions. This is similar in intent to TARGET_CPU, etc.

v1.7.13

  • Improvements
    • Verify the remote website when downloading artifacts. This fixes the warning about unverified HTTPS connections.
    • Fix error message printout when Nerves toolchain builds fail

v1.7.12

  • Improvements
    • Allow Elixir 1.13.0-rc.0 to be used to build projects. It looks like it works fine and doesn't cause issues with Nerves.
    • Add message after the build completes to let you know what to do next.

v1.7.11

  • Bug fixes
    • Don't set xattrs when running mix firmware.unpack. This fixes filesystem permission errors during extraction for some users.

v1.7.10

  • Improvements
    • Update mix firmware.unpack to be more flexible with input firmware and output directories. If you're using mix firmware.unpack in a script, you may need to update the script.
    • Reduce C compiler build prints

v1.7.9

  • Improvements
    • Add helper script generator for using gdb to analyze core dumps. Nerves systems ship with debug symbols (target images have these stripped) that can be used to get stack traces and more from core dumps from the Erlang VM and other C/C++ programs. See the Debugging C in Nerves blog post for an example.
    • Support the new :limits option in erlinit so that it's possible to set the core dump limits (i.e., enable core dumps) before Erlang starts.

v1.7.8

  • Bug fixes
    • Fix toolchain downloads when using Erlang/OTP 24 on Apple M1 macs.

v1.7.7

  • Bug fixes
    • Fix compiler version check error when using Erlang/OTP 24

v1.7.6

  • Enhancements
    • Update supported Elixir version to include 1.12

v1.7.5

  • Bug fixes
    • Fixes an issue where query parameters would be percent-encoded twice. Packages that use query_params argument option to artifact_sites could be impacted. For example, packages storing build artifacts in AWS S3 require the X-Amz-Credential query parameter key whose value includes the reserved character /. This symbol is double encoded to %252F. This failed on systems with Erlang OTP-23.2 and above. See #604 for additional context.

v1.7.4

  • Experimental features
    • Packages can provide custom system environment variables to be exported. The initial use case for this feature is to export system specific information for llvm-based tools.

v1.7.3

  • Bug fixes

    • Fixes a hang when downloading artifacts from GitHub. The hang looked like this and affected artifact downloads from public GitHub repositories:

      Resolving Nerves artifacts...
  Resolving nerves_toolchain_xyz
  => Trying https:...

v1.7.2

  • Bug fixes
    • Fix Elixir semver requirements to produce warnings on unsupported versions.
    • Produce better errors on HTTP timeouts

v1.7.1

  • Enhancements
    • Documentation and docker improvements for Windows Subsystem for Linux 2

v1.7.0

Nerves 1.7.0 removes support for creating OTP releases using Distillery and only supports using Elixir releases. As a result, the minimum supported version of Elixir is now version 1.9.

Official Nerves systems now support applying firmware using patches. This greatly reduces the amount of data that required to push firmware updates to devices. The minimum requirement for fwup has been updated to 1.8 to enable support for this feature.

  • Bug fixes
    • Pass all unspecified erlinit args to the generator instead of silently ignoring them.
    • Use host CC when compiling the port.

v1.6.5

  • Bug fixes
    • Fix issues with executing system commands on non mac hosts.

v1.6.4

  • Experimental features

    • Added mix firmware.patch to locally create firmware patch files for feature testing. This feature is under development. See the experimental features doc for more info.

    • Added :mksquashfs_flags to the nerves firmware config to allow passing additional flags to the mksquashfs call that produces the final rootfs. If you are experimenting with creating patchable firmware, you should use this feature to disable squashfs compression.

      config :nerves, :firmware
  mksquashfs_flags: ["-noI", "-noD", "-noF", "-noX"]

  • Bug fixes

    • Replace calls to System.cmd with a Nerves.Port.cmd. This code was provided by muontrap and is used to clean up spawned system processes when the vm exits. This fixes issues with the docker build runner executing multiple times and multiple calls to mix firmware after breaking out of the VM before the first call finishes.
    • Fix issue where SD card detection may fail while calling mix burn whenfwup returns additional fields.
    • Clean the release directory when calling mix firmware. This prevents OTP releases from accumulating unnecessary libraries and OTP applications over time.

v1.6.3

  • Bug fixes
    • Fix required key validation on github_api resolver.

v1.6.2

  • Bug fixes

    • Improve error message returned when calling mix firmware when the local system artifact cannot be found and possibly needs to be built.

    • GitHub API artifact resolver will no longer raise if missing required opts.

    The GitHub API artifact resolver is useful when you want to enable access to artifacts added to GitHub releases in private GitHub repositories. Fetching an artifact from a private GitHub repo requires the passing username, token, tag as options. If any of these options were omitted, the resolver would raise and prevent compilation from continuing. This is problematic when you are trying to actually compile the system in CI. Artifact resolvers should make a best effort on downloading the artifacts, and return {:error, reason} if they are unsuccessful. This will allow the system to fall back to performing a compile.

v1.6.1

  • Enhancements
    • Updated documentation to reflect changes in nerves_bootstrap 1.8 Updates references to nerves_init_gadget and replace with nerves_pack. This change shifts new projects and main documentation to promote the use of vintage_net for device networking.
    • Bump the host installed fwup version requirement to ~> 1.5.

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.

v1.4.1

  • Improvements
    • Improve error message when artifacts can't be found

v1.4.0

Version v1.4.0 adds support for Elixir 1.8's new built-in support for mix targets. In Nerves, the MIX_TARGET was used to select the appropriate set of dependencies for a device. This lets you switch between building for different boards and your host. Elixir 1.8 pulls this support into mix and lets you annotate dependencies for which targets they should be used.

See the project update guide to learn how to migrate your project.

v1.3.4

  • Bug fixes
    • Fixed issue where specifying build_runner_opts without build_runner would prevent build_runner_opts from being set.
    • Allow http_opts to be merged in from the artifact site opts. This fixes an issue with downloading artifacts from github enterprise by specifying [autoredirect: true] in the artifact site opts.

v1.3.3

v1.3.2

  • Bug fixes
    • Improved handling for burning firmware with Windows Subsystem for Linux.
    • mix nerves.deps.get will raise if a download was incomplete or corrupt after trying all resolvers.
    • mix firmware.burn will call mix firmware to ensure the firmware is the latest.
    • mix burn was added to allow for burning the latest built firmware without calling mix firmware.

v1.3.1

  • Bug fixes
    • Fix fwup invocations for NixOS users
    • Add --verbose option on mix firmware to help debug OTP release generation
    • Force users to run Elixir 1.7.3 or later if using Elixir 1.7. This avoids a known issue in Elixir 1.7.2 and Distillery 2.0.
    • Remove unused cookies in default rel/config.exs files

v1.3.0

This version adds support for Elixir ~> 1.7 which requires updates to your Mix project.

Modify the release config

It is required to modify the rel/config.exs file.

Change this:

release :my_app do
  set version: current_version(:my_app)
  plugin Shoehorn
  if System.get_env("NERVES_SYSTEM") do
    set dev_mode: false
    set include_src: false
    set include_erts: System.get_env("ERL_LIB_DIR")
    set include_system_libs: System.get_env("ERL_SYSTEM_LIB_DIR")
    set vm_args: "rel/vm.args"
  end
end

To this:

release :my_app do
  set version: current_version(:my_app)
  plugin Shoehorn
  plugin Nerves
end

Update shoehorn

You will need to update your version of shoehorn to {:shoehorn, "~> 0.4"}.

v1.2.1

  • Enhancements
    • Update minimum required version for fwup to at least 1.2.5

v1.2.0

  • Enhancements

    • Added ability to override provisioning.conf in the project mix config. This can be done by setting the key provisioning.

      Example:

      config :nerves, :firmware,
  provisioning: "config/provisioning.conf"

# or delegate it to an app that sets nerves_provisioning: "path/to/file"

config :nerves, :firmware,
  provisioning: :nerves_hub

    • Bug Fixes

      • Fix issue with setting provisioning environment variables when calling mix firmware.burn on Linux systems. Environment variables prefixed with NERVES_ and the variable SERIAL_NUMBER will be copied into the environment.

v1.1.1

  • Enhancements

    • Updated docs to bump required versions of tools.

  • Bug Fixes

    • Docker build runner
      • Use the version of the nerves_system_br as the tag for the docker image to pull by default.
      • Create and set the user id and group id in the docker entrypoint. This fixes issues with building buildroot packages that require access to the users home folder.

v1.1.0

  • Enhancements

    • mix firmware.burn can run within Windows Subsystem for Linux
    • Added make_args to build_runner_opts

    For example:

    You can configure the number of parallel jobs that buildroot can use for execution. This is useful for situations where you may have a machine with a lot of CPUs but not enough ram.

      # mix.exs
  defp nerves_package do
    [
      # ...
      build_runner_opts: [make_args: ["PARALLEL_JOBS=8"]],
    ]
  end

v1.0.1

  • Enhancements
    • General documentation updates.
  • Bug fixes
    • Do not fetch artifacts on deps.get if they are overridden using environment variables like NERVES_SYSTEM=/path/to/system.

v1.0.0

  • Bug Fixes
    • Nerves.Artifact.BuildRunners.Docker was running as root and caused file permission issues with the deps directory of the root mix project. The Docker build runner now executes as the same user id and group id as the host.

v1.0.0-rc.2

This version renames the module Nerves.Artifact.Provider to Nerves.Artifact.BuildRunner. This change should only affect custom systems and host tools that override the defaults in nerves_package config.

  • Enhancements
    • Allow specifying multiple rootfs_overlay directories in the config.
    • Automatically remove corrupt files from the download directory.
    • Updated System documentation.
  • Bug Fixes
    • Check the download directory before attempting to download the artifact.
    • Changed the host tool check to use System.find_executable("command") instead of calling out to System.cmd("which", ["command"]). This addressed an issue with NodeJS breaking anything that called into which resulting in an obscure error.

v1.0.0-rc.1

This rc contains documentation cleanup and updates through out.

  • Enhancements

    • Support forwarding the ssh-agent through Docker for the Nerves system shell.

    • Allow headers and query params to be passed to the :prefix artifact_sites helper.

      Example: {:prefix, "https://my_server.com/", headers: [{"Authorization", "Basic 1234"}]} {:prefix, "https://my_server.com/", query_params: %{"id" => "1234"}}

    • Added github_apito artifact_sites for accessing release artifacts on private github repositories.

      Example: {:github_api, "owner/repo", username: "skroob", token: "1234567", tag: "v0.1.0"}

  • Bug Fixes

    • Disable the nerves_package compiler if the NERVES_ENV_DISABLED is set. This makes it easier to execute mix tasks without building the system.

      Example: NERVES_ENV_DISABLED=1 mix docs

v1.0.0-rc.0

Nerves no longer automatically compiles any nerves_package that is missing its pre-compiled artifact. This turned out to rarely be desired and caused unexpectedly long compilation times when things like the Linux kernel or gcc got compiled.

When a pre-compiled artifact is missing, Nerves will now tell you what your options are to resolve this. It could be retrying mix deps.get to download it again. If you want to force compilation to happen, add a :nerves option for the desired package in your top level project:

  {:nerves_system_rpi0, "~> 1.0-rc", nerves: [compile: true]}
  • Bug Fixes
    • Mix raises a more informative error if the nerves_package compiler attempts to run and the nerves_bootstrap application has not been started. This also produces more informative errors when trying to compile from the top of an umbrella.

v0.11.0

  • Bug Fixes
    • Including the entire artifact checksum in artifact download file name was causing issues with file encryption libraries. Fixed by changing the artifact download name to only use the first 7 of the artifact checksum.

v0.10.1

  • Bug Fixes
    • Ensure the artifact cache dir is clean and created before putting artifacts.

v0.10.0

  • Enhancements

    • Call bootstrap/1 on any package that defines a platform
    • Added Nerves.Utils.File.tar helper for creating archives
    • Only apply the host tuple portable to packages with type system
    • Packages other then toolchains and systems can override their artifact paths using an env var of their app name. For example. a package called :host_tool would be able to override the artifact path by setting HOST_TOOL in the environment.
    • Allow any package that declares a provider to create an artifact.
    • Fixed up test fixtures and added integration test.

  • Bug Fixes

    • Do not raise when trying to make a directory when putting an artifact in the global cache.
    • Ensure the Nerves environment has been started when calling nerves artifact

v0.9.4

  • Bug Fixes
    • Fix artifact archiver to use Artifact.download_name/1 instead of Artifact.name/1. Fixes issues with the Docker provider and mix nerves.artifact
    • Fix issue with nerves.system.shell not rendering properly

v0.9.3

  • Bug Fixes
    • Artifact download_path should use download_name. This was causing a mismatch between dl files from buildroot and the resolver causing it to have to download them twice
    • Fixed issue with compiling certain nerves packages when calling mix deps.compile

v0.9.2

  • Bug Fixes
    • Fixed issue where env var artifact path overides were being calculated instead of honored.

v0.9.1

  • Bug Fixes
    • Fixed issue with artifact default path containing duplicate names
    • Nerves.Env.host_os can be set from $HOST_OS for use with canadian cross compile
    • Nerves.Env.host_arch can be set from $HOST_ARCH for use with canadian cross compile
    • mkdir -p on Artifact.base_dir before trying to link to build path artifacts
    • raise if artifact_urls are not binaries.

v0.9.0

  • Update Notes

Starting in Nerves v0.9.0, artifacts will no longer be fetched during mix compile. Artifact archives are intended to be fetched following mix deps.get. To handle this, you will need to update your installed version of nerves_bootstrap by calling mix nerves.local. After updating nerves_bootstrap, you should update your mix.exs file to add the new required mix aliases found there. A helper function is available named Nerves.Bootstrap.add_aliases that you can pipe your existing aliases to like this:

  defp aliases(_target) do
    [
      # Add custom mix aliases here
    ]
    |> Nerves.Bootstrap.add_aliases()
  end

Also, update your nerves dependency to:

{:nerves, "~> 0.9", runtime: false}

  • API Changes

    • Moved Nerves.Package.Providers to Nerves.Artifact.Providers
    • Moved Nerves.Package.Providers.HTTP to Nerves.Artifact.Resolver
    • Nerves.Artifact.Resolver no longer implements the Nerves.Artifact.Provider behaviour.

  • Enhancements

    • Added Mix task nerves.artifact.get. Use to fetch the artifact archive from an artifact_url location. Once downloaded its checksum will be checked against artifact_checksum from the nerves_package config in mix.exs. The Mix task nerves.deps.get will recursively call nerves.artifact.get to fetch archives.

    • Added Mix task nerves.artifact. This task will produce the artifact archive file which are used when calling nerves.artifact.get.

    • Nerves packages can override the Provider in the nerves_package config in mix.exs using the keys provider and provider_opts. This is useful to force a package to build using a specific provider like Nerves.Artifact.Providers.Docker. See the package configuration docs for more information.

    • Added artifact_sites to the nerves_package config. Artifact sites are helpers that are useful for cleanly specifying locations where artifacts can be fetched. If you are hosting your artifacts using Github releases you can specify it like this:

      artifact_sites: [
  {:github_releases, "organization/project"}
]

      You can also specify your own custom server location by using the :prefix helper by passing a url or file path:

      artifact_sites: [
  {:prefix, "/path/to/artifacts"}
  {:prefix, "https://my_bucket.s3-east.amazonaws.com/artifacts"}
]

      Artifact sites will be tried in order until one successfully downloads the artifact.

  • Bug Fixes

    • Fixed issue with Nerves.Utils.HTTPResolver crashing when missing the content-disposition and content-length headers.
    • Run integrity check on tar files to validate they are not corrupted on download.

v0.8.3

  • Bug Fixes

    • Revert plugin Nerves in new project generator until the fix can be made in distillery. This issue was causing the release to contain compiled libraries from the host instead of the target. The error would look similar to this

      Got:
ELF 64-bit LSB relocatable, x86-64, version 1

If binary, expecting:
ELF 32-bit LSB executable, ARM, EABI5 version 1, interpreter /lib/ld-linux.so.3, for GNU/Linux 4.1.39

      You can fix this by updating and regenerating the new project.

v0.8.2

  • Enhancements

    • Added contributing guide
    • Improved error messages when NERVES_SYSTEM or NERVES_TOOLCHAIN are unset.

  • Bug Fixes

    • Don't override the output_dir in the Distillery Plugin.

v0.8.1

  • Bug Fixes

    • Fixed an error in the Nerves Distillery plugin that was causing the following error message:

      Plugin failed: no function clause matching in IO.chardata_to_string/1

v0.8.0

  • Enhancements

    • Removed legacy compiler key from the package struct. The nerves_package compiler will be chosen by default.
    • Simplified the distillery release config by making Nerves a distillery plugin
    • Skip archival phase when making firmware.
    • Allow the progress bar to be disabled for use in CI systems by setting NERVES_LOG_DISABLE_PROGRESS_BAR=1
    • Deprecate nerves.exs. The contents of nerves.exs files have been moved into mix.exs under the project key nerves_package

  • Bug Fixes

    • raise an exception when the artifact build encounters an error

v0.7.5
