v1.20.0

This release updates to Buildroot 2022.05, Linux 5.15.32 (from Linux 5.10) and
uses GCC 11.3 (from GCC 10.3). The Linux kernel upgrade could introduce a
regression, so please verify hardware-specific functionality in your firmware.

If you have cloned this repository for a custom system, please make sure that
you have CONFIG_NOP_USB_XCEIV=y in your Linux kernel configuration.

• Updated dependencies
  • nerves_system_br v1.20.3
  • Buildroot 2022.05
  • Erlang/OTP 25.0.2

v1.19.0

This release updates to Buildroot 2022.02.1 and OTP 25.0. While this should be
an easy update for most projects, many programs have been updated. Please review
the changes in the updated dependencies for details.

• Updated dependencies
  • nerves_system_br v1.19.0
  • Buildroot 2022.02.1. Also see Buildroot 2022.02
  • Erlang/OTP 25.0

v1.18.4

This release bumps Erlang to 24.3.2 and should be a low risk upgrade from the
previous release.

• Changes

  • Pull in upstream Linux SquashFS patch to improve file system performance

• Updated dependencies

  • nerves_system_br v1.18.6

v1.18.3

This is a Buildroot and Erlang bug and security fix release. It should be a low
risk upgrade from the previous release.

• Updated dependencies
  • nerves_system_br v1.18.5

v1.18.2

This is a Buildroot and Erlang bug fix release. It should be a low risk upgrade
from the previous release.

• Updated dependencies

  • nerves_system_br v1.18.4

• Changes

  • Specify CPU-specific flags when compiling NIFs and ports. This fixes an
    issue where some optimizations could not be enabled in NIFs even though it
    should be possible to have them. E.g., ARM NEON support for CPUs that have
    it.
  • Build the Wireguard kernel driver. This is a small device driver that
    enables a number of VPN-based use cases.

v1.18.1

• Updated dependencies

  • nerves_system_br v1.18.3

• Changes

  • The cpufreq directories are available again. This was a regression that
    would break code that manually adjusted the CPU frequency.
  • Programs that use OpenMP will run now. The OpenMP shared library
    (libgomp.so) was supplied by the toolchain, but not copied.

v1.18.0

This release updates to Buildroot 2021.11 and OTP 24.2. If you have made a
custom system, please review the nerves_system_br release
notes
since Buildroot 2021.11 changed some Raspberry Pi firmware options.

• Updated dependencies

  • nerves_system_br v1.18.2
  • Buildroot 2021.11
  • Erlang/OTP 24.2
  • Raspberry Pi WiFi firmware
  • Linux 5.10.88 with Raspberry Pi patches
  • GCC 10.3

• Improvements

  • Support for the dl.nerves-project.org backup site. Due to a GitHub outage
    in November, there was a 2 day period of failing builds since some packages
    could not be downloaded. We implemented the backup site to prevent this in
    the future. This update is in the nerves_defconfig.
  • Use new build ORB on CircleCI. This ORB will shorten build times to fit in
    CircleCI's new free tier limits. Please update if building your own systems.

v1.17.3

• Updated dependencies
  • nerves_system_br v1.17.4
  • Buildroot 2021.08.2
  • Erlang/OTP 24.1.7.

v1.17.2

This release updates the Linux kernel from 5.4 to 5.10 to follow the Raspberry
Pi OS.

If you have a Raspberry Pi Zero 2 W, support is now available for it in
nerves_system_rpi3a.

• Updated dependencies
  • nerves_system_br v1.17.3
  • Erlang/OTP 24.1.4.
  • Linux 5.10.63 with Raspberry Pi patches

v1.17.1

This is a security/bug fix patch release. It should be safe to update for
everyone.

• Updated dependencies

  • nerves_system_br v1.17.1
  • Buildroot 2021.08.1
  • Erlang/OTP 24.1.2

• Improvements

  • Include software versioning and licensing info (see legal-info directory in
    artifact)
