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.
