v1.13.3

This releases enables the OpenGL ES drivers so that it's possible to run UI
libraries without a custom system. Note that the RPi4 uses the Linux DRM
interface rather than MMAL and so it is not compatible with Elixir UI libraries
that work on other Raspberry Pis.

• Updated dependencies
  • nerves_system_br: bump to v1.13.7
  • Erlang/OTP 23.1.5

v1.13.2

This release fixes the following issues found with the switch to 64-bit ARM:

• Circuits.GPIO can't set pullups
• 5 GHz WiFi is either flaky or doesn't work
• No GPU drivers

A huge thanks for people in the Nerves community that identified these issues
and helped verify the fixes.

This release also includes a patch release update to Buildroot
2020.08.2.

• Updated dependencies
  • nerves_system_br: bump to v1.13.5
  • erlinit 1.9.0

v1.13.1

IMPORTANT: This release runs the RPi4 in 64-bit ARM mode. This change was made
for many reasons. See
#65 for details.
While this is a big change, it is likely that it will not affect your programs
at all.

The second change in this release is to bump the Linux kernel to 5.4. This
follows the kernel update in the Raspberry Pi OS.

If you have based a custom system off of this one, please inspect all
configuration files for changes. In particular, WiFi firmware location has
changed since the rpi-wifi-firmware package went out of date. Git commit
messages on the nerves_system_rpi4 repository may also be helpful.

• Updated dependencies

  • nerves_system_br: bump to v1.13.4
  • Erlang/OTP 23.1.4
  • boardid 1.10.0

• Improvements

  • Enabled reproducible builds in Buildroot to remove some timestamp and build
    path differences in firmware images. This helps delta firmware updates.
  • The memory cgroup controller is no longer enabled by default. This was an
    upstream change. As a result, the memory cgroup directory is no longer
    mounted.

v2.0.0-rc.1

Sync with changes up to v1.13.0

v1.13.0

This release updates to Buildroot
2020.08 and OTP 23.1.1.

• Updated dependencies

  • nerves_system_br: bump to v1.13.2
  • Erlang/OTP 23.1.1
  • erlinit 1.8.0
  • nerves 1.7.0

• New features

  • Added support for updating the root filesystem using firmware patches.
    See the [firmware patch docs](https://hexdocs.pm/nerves/experimental-features.html

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.

v2.0.0-rc.0

• New Features
  • Uses nerves_initramfs to support pre-start checks for deciding if a
    firmware should automatically be reverted before the kernel is loaded.
    By default, this checks UBoot variable nerves_fw_validated and if the
    firmware has not been validated, a revert will be triggered. This means
    a user must validate the firmware on first boot via
    Nerves.Runtime.validate_firmware/0 or by writing to UBoot directly

v1.12.1

• Fixes
  • Remove nerves_system_linter from hex package. This fixes mix dependency
    errors in projects that reference systems with different
    nerves_system_linter dependency specs.

v1.12.0

This release updates the system to use Buildroot 2020.05 and Erlang/OTP 23.
Please see the respective release notes for updates and deprecations in both
projects for changes that may affect your application.

• New features

  • Support the Raspberry Pi Sense HAT's joystick
  • Enable WiFi mesh support in the 802.11 stack

• Updated dependencies

  • nerves_system_br v1.12.0
  • Erlang/OTP 23.0.2
  • Linux 4.19.118 (Raspberry Pi 1.2020601 tag)
  • Raspberry Pi firmware 1.2020601

v1.11.3

• Updated dependencies
  • nerves_system_br v1.11.4
  • Erlang 22.3.4.1
  • fwup 1.7.0
