0.17.0

Added

• An open document reloads itself when the file changes. Reading a spec
  while an agent rewrites it used to show you the version you opened; the viewer
  now notices the new file and re-renders it where you were reading, scroll
  position kept. It follows a save that replaces the file wholesale — a temp
  file plus a rename — which is how editors and agents usually write, and waits
  for the writing to stop before re-rendering. A document in a background tab
  isn't watched at all; it catches up when you come back to it.

Changed

• Documents load their remote images by default. The badge row of a README
  now fills in on its own instead of waiting for the globe button, which was one
  click too many for something every git host renders without asking. The button
  and the Settings checkbox still turn it off, per machine, and everything else
  about the fetch is unchanged: no cookies, https only, 2 MB and 6 seconds per
  image.
