It took a lot longer than it should have, but Chromium 53.0.2785.143 has
finally hit Crosswalk master (aka Crosswalk 23).
One of the biggest changes from a developer point of view is that gyp is
now fully *UNSUPPORTED*. gyp_xwalk is no longer run by default when
calling `gclient sync', and it is not expected to work. You MUST switch
to GN if you have not already done so. Instructions here:
We will remove the gyp code from the tree in the near future.
