* New upstream release.
  - `system-image-cli --info` prints additional information:
     + last update time (i.e. the mtime of `/etc/system-image/channel.ini`
       falling back to the mtime of `/etc/ubuntu-build`).
     + version details for ubuntu, the device, and any custom version, if the
       `/etc/system-image/channel.ini` file contains these details.
  - `system-image-cli --dry-run -c <bad-channel>` no longer produces a
     traceback.  You get "Already up-to-date", but use `-v` for more info.
  - D-Bus API method `UpdateAvailableStatus` field `last_update_date`
    has changes its format.  It's still ISO 8601, but with a space
    instead of a 'T' separating the date from the time.
  - LP: #1221841 - Support the new channels.json file format with
    backward compatibility (for now) with the old format.
  - LP: #1215959 - New D-Bus .Info() method returns data similar to
    `system-image-cli --info`
