UltraDefrag 12
  - the graphical interface was overhauled with a modern design that not only
    boosts aesthetics but also takes functionality to the next level
    + the new interface comes with two eyestrain reducing color themes:
      light and dark; the light theme is optimized for daytime use,
      the dark one is perfect for use in dark environments
    + you can easily switch between color themes manually or set the interface
      to always match the color theme of Windows
    + an option to prevent system from going into sleep during disk processing
      was added
    + an option to automatically pause disk processing on AC power outages
      was added; being enabled this option prevents excessive drain of your
      batteries during AC power outages; if you're using a generator to keep
      your computer running instead of batteries, enable this option to save
      some fuel
    + all settings now have a description
    + all settings changes get applied immediately, there's no need to click
      the Apply button anymore

UltraDefrag 11
  - all the program modules were highly optimized for speed
  - an option to remove temporary files before defragmentation was added, it
    releases space on your disks and leads to much better defragmentation results
  - individual files and folders defragmentation component was redesigned,
    now it uses much more convenient graphical interface instead of the
    command line interface:
    + the new interface doesn't analyze entire disks, but analyzes the selected
      files only, thus completing the job much faster (on average 10x faster)
    + the new interface visually displays defragmentation progress
    + you can pause, resume, stop and restart defragmentation at any moment
      via a single click
    + now you can open the file fragmentation report directly from the new interface
      via a single click to quickly check which files are fragmented and why
    + you can minimize the new interface to the system tray
    + the entire interface is fully translated to all major languages
    + the new interface displays filenames containing Unicode characters correctly
  - files search was added to the file fragmentation reports
