v0.8.0

• Enhancements

  • Optimized enumeration of devices at boot. You will likely notice devices
    becoming available more quickly. This may uncover race conditions in
    application initialization code.
  • The syslog monitoring code has been rewritten in pure Elixir. This
    component captures log messages sent by C programs using the syslog system
    call so that they can be handled by Elixir Logger backends.
  • The kmsg log monitor still requires C, but the C code is simpler now that it
    doesn't process syslog messages as well.
  • The Linux uevent processing code was simplified and the C to Elixir
    communications refactored to minimize processing of events.

• Bug fixes

  • Fixed a race condition with the Linux kernel and processing /sys/devices
    that could cause an exception during device enumeration.
  • Syslog messages w/o terminating newlines are logged now.

v0.7.0

• Enhancements

  • Documentation updates to nerves_serial_number, nerves_validated, and
    nerves_autovalidate.
  • Added helper function Nerves.Runtime.KV.UBootEnv.put/2 for writing to the
    UBoot env. This is useful for setting provisioning information at runtime.
  • Added the ability to mock the contents of Nerves.Runtime.KV for use in
    test and dev. The contents can be set in your application config.

    config :nerves_runtime, :modules, [
      {Nerves.Runtime.KV.Mock, %{"key" => "value"}}
    ]
    

• Bug fixes

  • Kernel UEvent change messages no longer cause modifications to
    system_registry.

v0.6.5

Update dependencies to only include dialyxir for [:dev, :test], preventing it
from being distributed in the with the hex package. This addresses an issue
where dialyxir and its dependencies would be included in the applications list
when producing the OTP release and cause :wx to raise because the target
version of erts was compiled without it.

v0.6.4

• Bug fixes
  • Fix U-Boot environment load issue and add unit tests to cover environment
    block generation using either U-Boot tools or fwup
  • Load rngd if available. If it's available, this greatly shortens the time
    for the Linux kernel's random number entropy pool to initialize. This
    improves boot time for applications that need random numbers right away.

v0.6.3

• Bug fixes
  • Fix issue with parsing fw_env.config files with space separated values.

v0.6.2

• Enhancements

  • Updates to docs and typespecs.

• Bug fixes

  • Read the U-Boot environment directly using :file if possible. (OTP-21)
    This fixes an issue with fw_printenv where multi-line values cause the
    output to be unparseable.

v0.6.1

• Bug fixes
  • Log the output of system commands to that they're easier to review
  • Support mounting f2fs (requires support in the Nerves system to work)

v0.6.0

• New features

  • Forward operating system messages from /dev/log and /proc/kmsg to
    Elixir's Logger. If the log volume is too much to the console, consider
    replacing the console logger with ring_logger or another logger backend.

• Bug Fixes

  • cmd/1 helper improvements to interactively print output from long running
    commands.
  • Nerves.Runtime.revert would always reboot even if told not to.
  • Cleanup throughout to improve docs, formatting, and newer Elixir stylistic
    conventions
  • Remove scary suid printout when crosscompiling since nothing setuid related
    was going on.

v0.5.2

• Enhancements

  • Added Nerves.Runtime.revert to revert the device to the inactive
    firmware. To use this, the Nerves system needs to include revert
    instructions. This is currently being implemented.

• Bug Fixes

  • Setuid the uevent port binary for debugging on the host.

v0.5.1

• Bug Fixes
  • Split device attributes into only two parts
