# Changelog

## v1.12.2

This release updates to [Buildroot
2020.05.1](http://lists.busybox.net/pipermail/buildroot/2020-July/287824.html)
and OTP 23.0.3 which are both bug fix releases.

* Updated dependencies
  * [nerves_system_br: bump to v1.12.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.12.4)
  * [Erlang/OTP 23.0.3](https://erlang.org/download/OTP-23.0.3.README)
  * [nerves_heart v0.3.0](https://github.com/nerves-project/nerves_heart/releases/tag/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.

## 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

## v1.11.0

This release updates Buildroot to 2020.02 and upgrades gcc from 8.3 to 9.2.
While this is a minor version bump due to the Buildroot release update, barring
advanced usage of Nerves, this is a straightforward update from v1.10.2.

* Updated dependencies
  * [nerves_system_br v1.11.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.11.0)
  * linux 4.19.97 (raspberrypi-kernel_1.20200212-1 tag)
  * Erlang 22.2.8

## v1.10.2

* Fixes
  * This fixes a regression on OSX where the USB gadget Ethernet would
    incorrectly try to go into RNDIS mode and not work. Gadget Ethernet works
    with this fix on Linux and OSX. It also works on Windows with a driver
    installed.

* Updated dependencies
  * [nerves_system_br v1.10.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.10.2)
  * Erlang 22.2.4

## v1.10.1

This release changes the behavior of the gadget port as well as the UART pins
on the GPIO header. The gadget driver has been changed to use g_ether. This
provides a more stable network connection at the expense of the virtual serial
port. Console access has been output to the UART. If you were using the UART
to connect to peripherals, you will need to disable the console.
See: https://hexdocs.pm/nerves/advanced-configuration.html#overwriting-files-in-the-boot-partition
for more information.

* Enhancements
  * Set `expand=true` on the application data partition. This will only take
    effect for users running the complete task, fwup will not expand application
    data partitions that exist during upgrade tasks.
  * linux: swap the cdc composite gadget for g_ether

* Updated dependencies
  * [nerves_system_br v1.10.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.10.1)

* Updated dependencies
  * [nerves_system_br v1.7.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.7.2)

## v1.7.1

This release fixes a major issue with the gadget USB port where it would hang on
boot. If you have made a custom system or are overriding the `erlinit.config`
file in your project, please make sure that your `erlinit.config` has:

```text
-c null
-s "/usr/bin/nbtty --tty /dev/ttyGS0 --wait-input"
```

* Bug fixes
  * Fix regression with virtual serial port where it could cause the whole USB
    interface to hang.

* Improvements
  * Bump C compiler options to `-O2` from `-Os`. This provides a small, but
    measurable performance improvement (500ms at boot in a trivial RPi0 project).

* Updated dependencies
  * [nerves_system_br v1.7.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.7.1)

## v1.7.0

This release bumps the Linux kernel to 4.19.25. This change had an impact on how
the WiFi regulatory database gets loaded into the kernel. Instead of building it
into the kernel as previously done, the kernel loads it on demand. This requires
that all WiFi drivers be built as kernel modules so that the database isn't
loaded before the root filesystem is mounted. If you made a custom system and
see boot errors about not being able to load the regulatory database, this is
the problem.

A known bug with the Raspberry Pi Zero USB gadget interface is that it sometimes
doesn't load on Linux systems. Moving the gadget drivers to kernel modules seems
to work around this but it takes longer to load the gadget interface.

* Updated dependencies
  * [nerves_system_br v1.7.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.7.0)
  * Linux 4.19.25 with patches from the Raspberry Pi Foundation

  * Erlang 21.2.4
  * boardid 1.5.3

## v1.6.1
