v2.0.0-beta.12

2.0.0-beta.12

Changed

• Every onClose passed while the viewer is open is called once when it
  closes, not only the last one. Opening over a viewer that is still open
  used to drop the first opener's, so the Files app never cleaned
  openfile=true out of its URL when a handler handed its file to
  another one with open(). The same function passed twice is still
  called once, and one that throws does not stop the others (#66)
• The options filled in for a caller that passes none no longer carry
  no-op callbacks. The viewer always called them optionally (#66)

Fixed

• Clicking rotate again while the previous turn was still being written
  could undo it, and every turn made the picture flash once written.
  Writes now wait for each other and build on the bytes just sent, and
  the viewer no longer reloads a picture it is already showing turned
  (#61)
• The right-click menu is refused on a share that hides or forbids
  the download: the check read the old viewer's names for those
  restrictions, not the ones nodes carry, hide-download and
  share-attributes (#65)
• Registering the same handler twice, as the server's copy and an app's
  do with the defaults, no longer warns. Another handler taking an id
  that is already used still does (#64)
• The header is readable on the dark backdrop (#60)

Documentation

• A tutorial that builds a handler from scratch, and a reference that
  lists every option and the whole migration from OCA.Viewer (#67)
