    * Fix excessive memory consumption when showing long-running slideshows
      with thousands to tens of thousands of images and feh has been compiled
      with exif=1 (see https://github.com/derf/feh/issues/553)
    * Fix memory leak when showing long-running slideshows with relatively few
      images and feh has been compiled with exif=1 (ibid.)

      exif=1

* Release v3.6
    * Add flip and rotate options to the menu
    * Improve unloadable image detection time (e.g. for large video files) by
      checking a file's header before passing it to Imlib2. For rarely used
      image formats, there is a very small chance that an image which could be
      loaded by feh 3.5 is reported as unloadable by feh 3.6 due to this
      change. Set FEH_SKIP_MAGIC=1 to bypass the header check in this case. See
      <https://phab.enlightenment.org/T8739> and
      <https://github.com/derf/feh/issues/505> for details.
