Changelog

v0.6.1

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.

v0.6.0

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.

v0.5.0

This release updates to Buildroot 2020.11.2, GCC 10.2 and OTP 23.2.4.

When migrating custom systems based, please be aware of the following important changes:

  • There's a new getrandom syscall that is made early in BEAM startup. This has the potential to block the BEAM before Nerves can start rngd to provide entropy. We have not seen this issue here, but have updated erlinit.config for the time being as a precaution.

  • The GCC 10.2.0 toolchain has a different name that calls out "nerves" as the vendor and the naming is now more consistent with other toolchain providers.

  • Experimental support for tooling that requires more information about the target has been added. The initial support focuses on zigler.

  • Updated dependencies

v0.4.3

This is a bug fix release and contains no major changes.

v0.4.2

This release includes a patch release update to Buildroot 2020.08.2.

v0.4.1

v0.4.0

This release updates to Buildroot 2020.08 and OTP 23.1.1.

v0.3.2

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

  • Updated dependencies

  • 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.

v0.3.1

  • 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.

v0.3.0

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.
