v1.16.5

• Improvements
  • Make shell script shebang lines consistently call /usr/bin/env to find
    bash. This fixes an issue with NixOS and possibly other setups. Thanks to
    @mayl for this change.
  • Resync Busybox configuration. This removes the mim and base32 applets
    that were turned on by default on a update.

v1.16.4

This is primarily a bug fix release for Buildroot and Erlang/OTP. The Erlinit
update brings in beta support for including a
runtime.exs
in your project. This support is new and may lead to reboot loops if you have
not configured your system to revert to previous firmware loads on failures.

• Package updates
  • Buildroot 2021.05.1
  • Erlang/OTP 24.0.5
  • erlinit 1.11.0

v1.16.3

• Package updates

  • Erlang/OTP 24.0.4

• Improvements

  • Adds a default /etc/sysctl.conf file to support setting kernel parameters
    on initialization. This requires a nerves_runtime v0.11.5 or later. The
    current default only enables non-root use of ICMP. This simplifies use of
    ICMP in Erlang and Elixir.

• Bug fixes

  • Fixes an issue on MacOS where if you had /home in your $PATH, mix firmware could go from taking 10 seconds to many minutes to run due to the
    merge-squashfs script. Thanks to Jonathan Palley for some serious
    detective work to narrow this issue down.
  • Fixes an issue on MacOS with exclusing files from the scrubber.

v1.16.2

• Package updates

  • fwup 1.9.0

• Improvements

  • Software Bill of Materials (SBOM) information from Buildroot can now be
    packaged with Nerves systems. The system needs to add pkg-stats and/or
    legal-info to the make targets to use. This is an experimental update and
    will likely be changed and improved. Note that SBOM info has always been
    available, but it just hasn't been convenient. We're trying to make it more
    accessible.
  • It's now possible to build on aarch64 Linux machines.

v1.16.1

• Package updates
  • Erlang/OTP 24.0.3
  • erlinit 1.10.0
  • boardid 1.11.1
  • bborg-overlays: bump to latest SHA (device tree updates for BBB)

v1.16.0

This is a major update to Buildroot 2021.05. Please review the Buildroot release
notification below in addition to the following.

1. The wpa_supplicant options in Buildroot changed. If you're using
   vintage_net_wifi, you'll need to make sure that the control interface is
   enabled now. Add the following to your nerves_defconfig:

   BR2_PACKAGE_WPA_SUPPLICANT_CTRL_IFACE=y
   

• Package updates

  • Buildroot 2021.05
  • Erlang/OTP 24.0.2
  • Broadcom WiFi firmware for Raspberry Pis 1:20190114-1+rpt11. Despite the
    version number, this is the latest from Raspberry Pi OS.

• Improvements

  • Build Nerves on RISC-V platforms. RISC-V is not officially supported, but
    experiments are ongoing as low cost hardware becomes available.

v1.15.2

This is a security/bugfix release for Buildroot and Erlang.

• Package updates

  • Buildroot 2021.02.2
  • Erlang/OTP 23.3.4

• Improvements

  • Various shellcheck warning fixes that make paths with spaces work in more
    places. Thanks to @pojiro for this.

v1.15.1

This is a security/bugfix release for Buildroot and Erlang.

• Package updates
  • Buildroot 2021.02.1
  • Erlang/OTP 23.3.1

v1.15.0

This is a major update to Buildroot 2021.02. Please review the Buildroot release
notification below in addition to the following. The following changes affect
all systems:

1. The rngd daemon's jitter entropy option changed defaults. This daemon feeds
   values from a hardware random number generator to the Linux kernel's entropy
   pool. Without it, you can experience long boot delays as programs wait for
   enough entropy to get good random numbers. Jitter entropy is a way of
   gathering entropy from the CPU without any special random number generation
   hardware. It's not necessary with most hardware with Nerves and it adds a
   boot-time delay as the CPU is measured. Previously Nerves defaulted it to off, but
   now it is consistent with Buildroot's default. To retain the previous behavior,
   you need to add the following to your nerves_defconfig:

   # BR2_PACKAGE_RNG_TOOLS_JITTERENTROPY_LIBRARY is not set
   

2. Buildroot changed how it computes hashes over projects downloaded from
   version control systems. If you have made a custom system and added your own
   packages, you may need to update the .hash files to -br1 versions. The
   files are different so the existing checksums will not match. See buildroot
   5b95a5d
   for more info.

3. The nervesproject/nerves_system_br Docker image that corresponds to this
   release has been updated from Ubunto 18.04 LTS to Ubuntu 20.04 LTS. This
   fixed an internal compiler error that was seen, but resulted in some package
   changes (no more Python 2, for example) that might affect scripts using it.

• Improvements

  • It's now possible to include executable files for other CPU architectures in
    the root filesystem without have the scrubber find them and report an error.
    To use this feature, add the file .noscrub to the directory with the files.

• Package updates

  • Buildroot 2021.02
  • Erlang/OTP 23.2.7

v1.14.5

This release is a security and bug fix release for Buildroot and Erlang/OTP.

• Improvements

  • Add CPPFLAGS for projects that only use the C preprocessor
  • Clear out PKG_CONFIG_PATH to avoid confusion with host settings

• Package updates

  • Buildroot 2020.11.3
  • Erlang/OTP 23.2.5
