# Changelog
## v0.5.2
This is a security/bug fix patch release. It should be safe to update for
everyone.
* Updated dependencies
* [nerves_system_br v1.17.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.17.1)
* [Buildroot 2021.08.1](http://lists.busybox.net/pipermail/buildroot/2021-October/625642.html)
* [Erlang/OTP 24.1.2](https://erlang.org/download/OTP-24.1.2.README)
* Improvements
* Include software versioning and licensing info (see legal-info directory in
artifact)
## v0.5.1
This fixes a regression that happened when the toolchain was updated to require
Linux kernel headers newer than the kernel used in this project. Rather than
holding the kernel version back, I updated it to Linux 5.10. This is beyond what
Seeed supports (4.19), but it's 2021 and Linux 5.10 appears to work well.
* Updated dependencies
* Linux 5.10.59
## v0.5.0
This release updates to Buildroot 2021.08 and OTP 24.1. If you have made a
custom system off this one, please review the `nerves_system_br v1.17.0` release
notes.
* Updated dependencies
* [nerves_system_br v1.17.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.17.0)
* [Buildroot 2021.08](http://lists.busybox.net/pipermail/buildroot/2021-September/622072.html)
* [Erlang/OTP 24.1](https://erlang.org/download/OTP-24.1.README)
## v0.4.2
This release updates Erlang/OTP from 24.0.3 to 24.0.5 and Buildroot from 2021.05
to 2021.05.1. Both of these are security/bug fix updates. This is expected to be
a safe upgrade from v1.16.1 for all users.
* Updated dependencies
* [nerves_system_br v1.16.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1)
* [Erlang/OTP 24.0.5](https://erlang.org/download/OTP-24.0.5.README)
* Improvements
* Beta support for using a `runtime.exs` script for runtime configuration.
* Added a `provision` task to the `fwup.config` to enable re-provisioning a
MicroSD card without changing its contents.
* Adds a default `/etc/sysctl.conf` that enables use of ICMP in Erlang. This
requires `nerves_runtime v0.11.5` or later to automatically load the sysctl
variables. With it using `:gen_udp` to send/receive ICMP will "just work".
It also makes it easier to add other sysctl variables if needed.
## v0.4.1
This release updates Nerves Toolchains to v1.4.3 and OTP 24.0.3. It should be
safe for everyone to apply.
* Updated dependencies
* [nerves_system_br v1.16.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1)
* [Erlang/OTP 24.0.3](https://erlang.org/download/OTP-24.0.3.README)
* [nerves toolchains v1.4.3](https://github.com/nerves-project/toolchains/releases/tag/v1.4.3)
## v0.4.0
This release updates to Buildroot 2021.05 and OTP 24.0.2. If you have made a
custom system off this one, please review the `nerves_system_br v1.16.0` release
notes.
* Updated dependencies
* [nerves_system_br v1.16.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.0)
* [Buildroot 2021.05](http://lists.busybox.net/pipermail/buildroot/2021-June/311946.html)
* [Erlang/OTP 24.0.2](https://erlang.org/download/OTP-24.0.2.README)
* Improvements
* This release now contains debug symbols and includes the Build-ID in the
ELF headers. This makes it easier to get stack traces from C programs. As
before, the Nerves tooling strips all symbols from firmware images, so this
won't make programs bigger.
## v0.3.1
This is a security/bug fix release that updates to Buildroot 2021.02.1 and OTP
23.3.1. It should be safe for everyone to apply.
* Updated dependencies
* [nerves_system_br v1.15.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.1)
* [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-April/307970.html)
* [Erlang/OTP 23.3.1](https://erlang.org/download/OTP-23.3.1.README)
## v0.3.0
This release updates to Buildroot 2021.02 and OTP 23.2.7. If you have made a
custom system off this one, please review the `nerves_system_br v1.15.0` release
notes.
The Nerves toolchain has also been updated to v1.4.2. This brings in Linux 4.14
headers to enable use of cdev and eBPF. This won't affect most users.
* Updated dependencies
* [nerves_system_br v1.15.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.0)
* [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-March/305168.html)
* [Erlang/OTP 23.2.7](https://erlang.org/download/OTP-23.2.7.README)
* [nerves toolchains v1.4.2](https://github.com/nerves-project/toolchains/releases/tag/v1.4.2)
## v0.2.1
* Improvements:
* Load device tree overlays for I2C, SPI and UART so that the "Raspberry Pi"
GPIO headers work more like the Raspberry Pi by default
* Synchronize with official systems
## v0.2.0
This updates the system to the `nerves_system_br 1.14.x` series and updates the
toolchain to use gcc 10.
* Updated dependencies
* [nerves_system_br: bump to 1.14.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.14.4)
* [Erlang/OTP 23.2.4](https://erlang.org/download/OTP-23.2.4.README)
## v0.1.1
* Updated dependencies
* [nerves_system_br: bump to v1.13.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.4)
* [Erlang/OTP 23.1.4](https://erlang.org/download/OTP-23.1.4.README)
* [boardid 1.10.0](https://github.com/nerves-project/boardid/releases/tag/v1.10.0)
## v0.1.0
This is the initial release. The basics work: MicroSD boot, Linux, both Ethernet
ports, the RTC, DT overlays, firmware updates. The display and eMMC support are
untested and likely require work. Only a cursory skim of power management and
other peripherals has been made so far.
