v1.33.1

This is a security and bug fix release.

• Changes

  • Fix camera support by enabling the unicam-legacy Linux device driver

• Package updates

  • nerves_system_br 1.33.2
    • Erlang/OTP 28.3.1
    • Buildroot 2025.11.1

v2.0.0

This is a major update of nerves_system_rpi4 that changes the MicroSD/eMMC
layout in order to support automatic rollback of non-working firmware updates.

IMPORTANT This is a one way upgrade. Going back to the old partitioning
requires manually reflashing of the RPi's storage.

Previous releases assumed that firmware updates worked. This one requires that
firmware images mark themselves as good using
Nerves.Runtime.validate_firmware/0. See Nerves.Runtime for more information
on this. Firmware not marked as good reverts back to the previous version.

• Changes

  • Fix camera support by enabling the unicam-legacy Linux device driver
  • Enabled multipath TCP support in the Linux kernel
  • Deleted all use of nerves_fw_active since it was sometimes incorrect and
    caused confusion

• Package updates

  • nerves_system_br 1.33.2
    • Erlang/OTP 28.3.1
    • Buildroot 2025.11.1

v2.0.0-rc.3

• Changes
  • Fixed typo in fwup.conf preventing use of 2.0.0-rc.2
  • Deleted all use of nerves_fw_active since it was sometimes incorrect and
    caused confusion
  • Enabled multipath TCP support in the Linux kernel

v2.0.0-rc.2

v1.33.0

This is a major Buildroot and Linux update. It should be seamless for most
1.32.0 users.

• Changes

  • Refresh ramoops-overlay.dts. This actually changes the default pstore
    settings to reserve less DRAM based on experience of not needing nearly as
    much. Settings can be overridden now via the config.txt.
  • Use EEx to generate the fwup.conf. This removes a lot of repetition. If
    you've made a custom fwup.conf, please review git commit log for details.
  • Add 5" Raspberry Pi Touch Display overlay

• Updated dependencies

  • Linux 6.12.47
  • nerves_system_br 1.33.0
