v1.12.2

This release updates to Buildroot
2020.05.1
and OTP 23.0.3 which are both bug fix releases.

• Updated dependencies

  • nerves_system_br: bump to v1.12.4
  • Erlang/OTP 23.0.3
  • nerves_heart v0.3.0

• New features

  • The /data directory now exists for storing application-specific data. It
    is currently a symlink to /root. Using /data will eventually be
    encouraged over /root even though currently there is no advantage. This
    change makes it possible to start migrating paths in applications and
    libraries.

• Fixes

  • Fixed old references to the -Os compiler flag. All C/C++ code will default
    to using -O2 now.
