v0.12.0

This image is backwards incompatible with previous ones, so over-the-air
upgrades won't work. In theory, it's possible to make them work. If you
installed a previous version of Nerves onto your LinkIt Smart, this version will
force you to update the Linux kernel on the NAND Flash. Boot this one and run:

:os.cmd("dd if=/boot/uImage of=/dev/mtdblock3 bs=1M")

This one's Linux kernel supports the ext4 file system. Without the new kernel,
the application partition won't mount.

• nerves_system_br v0.12.1

  • Buildroot 2017.05
  • Erlang/OTP 19.3
  • erlinit 1.1.1
  • fwup 0.15.0

• New features

  • The application data partition is now ext4. This greatly improves its
    robustness to corruption. Nerves.Runtime contains code to initialize it on
    first boot.
  • Firmware images now contain metadata that can be queried at runtime (see
    Nerves.Runtime.KV
