v0.4.6

• New features
  • Added mix upload task for Nerves users who prefer idiomatic Elixir ways of
    uploading to devices. This task has some limitations especially when
    ssh needs to ask for passwords. The mix firmware.gen.script /
    ./upload.sh approach still exists.

v0.4.5

• Bug fixes
  • Fix issue causing ssh to hang at the end of a successful firmware update.
    Now the socket is properly closed before the reboot.

v0.4.4

• Bug fixes
  • fwup is now stopped immediately when the ssh connection closes prematurely.
    This cancels any existing firmware update. Thanks to Troels Brødsgaard for
    this fix.

v0.4.3

• Improvements
  • Minor project cleanup. No functional changes.

v0.4.2

• Improvements
  • Validate authorized ssh keys to avoid accidents that prevent firmware
    updates
  • Print out firmware metadata when uploading

v0.4.1

• Improvements
  • Updated upload.sh script to support Elixir 1.8 changes to output paths

v0.4.0

Support for mix firmware.push has been removed. We're all very sorry for this,
but it appears to be unfixable. It was implemented using Erlang's built-in ssh
client which doesn't know about things like the ssh-agent or the .ssh/config
and can't ask for passwords. It also isn't possible to call the system's ssh
since Erlang runs setsid on child processes so they don't have a tty.

The workaround is to run mix firmware.gen.script and then run ./upload.sh.

• Bug fixes
  • Fix exit code parsing from fwup so that errors can be propogated over ssh
  • Disabled the Erlang shell and remote command execution on the firmware
    update port

v0.3.3

• Bug fixes
  • Fixed exit code returned over ssh so that uploads could be scripted and
    checked that they ran successfully.

v0.3.2

• Bug fixes
  • Removed workaround for ERL-469 that prevented use of ssh-agent. This
    requires Erlang >= 20.2.1 running on the target. That's been out for a while
    in the official systems, so hopefully people have upgraded.

v0.3.1

• Improvements
  • Try guessing the link local interface when multiple exist on OSX. Guessing
    the last one seems to work.
