* Release v2.15
    * Patch by William Woodruff: Add --insecure option to disable HTTPS
      certificate checks
    * Patch by guraga: Add --no-recursive option to disable recursive directory
      expansion.  Note that --no-recursive is the default behaviour of feh.
      This option is mostly useful to override a --recursive set in a theme or
      shell alias
    * Patch by Richard Molitor: Improve --scale-down in tiling environments.
      This fixes flickering when changing images at the cost of slightly
      less apaptive scale-down behaviour: Window size changes are now only
      processed when the active image is changed
    * --action and --action[1..9] now support action titles
      (e.g. --action '[some title]some-command %F'), which are displayed
      instead of the specified shell command. Note that the title must not
      start with a space. Titles starting with a space are treated as part of
      of the command so that actions like '[ -L %F ] && foo' still work
