Version 12.0.0 2024-03-30
------------------------------------------------------------------------------
  - 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
    + the new interface comes with a handy Help dialog which contains links
      to documentation, troubleshooting resources and contact information
    + the settings and help dialogs remember the last open tab between runs,
      so now you can pick up right where you left off
    + the new interface includes visual indication of the amount of free
      space available on your disks, so you can quickly decide whether to run
      a disk cleanup utility before defragmentation or not
    + during the disk processing the new interface indicates the progress of
      the current operation visually and also displays how much disk space
      has been already processed and how much still needs to be processed;
      this greatly helps to estimate the remaining disk processing time
    + the new interface includes visual indication of the disk fragmentation
      level and also displays the amount of solid and loose fragments, so now
      you can make a more informative decision whether to defragment or optimize
      your disks
    + now you can explore details of all the already processed disks while
      the disk processing is still running
    + all windows are fully responsive, i.e. they deliver a consistent user
      experience across all screen sizes
    + the new interface reduces CPU load by utilizing GPU accelerated graphics
  - all the program modules were further optimized for speed
  - compatibility with Windows 11 and latest Windows 10 updates was improved
  - Japanese and Tamil translations of the graphical interface were improved
  - wxWidgets library was updated to the latest 3.2.4 version

Version 11.0.0 2023-04-02
------------------------------------------------------------------------------
  - 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
  - compatibility with Windows 11 was improved
  - compatibility with HiDPI displays was improved
  - ability to correct detected disk types was added; if some of your disks
    are incorrectly identified as SSD/HDD due to internal Windows bugs, now
    you can easily fix that with just a few clicks
  - --mark-as-ssd and --mark-as-hdd switches were added to the command line
    interface for easy correction of the disk types detection from batch scripts
  - supplementary scripts were integrated into the installers, now you can use
    the `bt`, `setenv`, `clearenv` and `show-report` commands right after the
    installation
  - the following translations of the graphical interface were improved:
    Chinese, French, German, Italian, Japanese, Polish, Portuguese and Spanish
  - wxWidgets library was updated to the latest 3.2.2.1 version
  - UltraDefrag Support Center (https://support.ultradefrag.net) was created,
    now you can easily recover lost UltraDefrag installers and passwords
  - a small bug causing the user credentials check to fail for the usernames
    containing plus signs was fixed
  - Windows XP, Vista, Server 2003 and Server 2008 support was dropped, because
    it hinders addition of new features and, according to our survey results,
    just a few people still use such ancient versions of Windows nowadays
  - support of Itanium editions of Windows was dropped to reduce maintenance
    costs (according to our survey results, very few people use Itanium editions
    of Windows nowadays)

    respectively and white for free space

Beta Stage
------------------------------------------------------------------------------
  All versions listed below were treated as stable and so on, but actually
  they were highly unreliable. Program's internal structure is very complex,
  it uses a lot of undocumented Windows calls. Therefore bug hunting was
  always extremely hard, especially in early days when an author had
  no enough experience.

  In other words, all versions prior to 4.0.0 must be treated as products
  of the beta stage of program's development.


Version 3.3.0  2009-12-04
------------------------------------------------------------------------------
  - volume optimization algorithm was highly improved
  - fragments threshold filter parameter was added

  - few little bugs were fixed
  - now the program is much more compatible with Vista and later versions
    of Windows; this is achieved by adding the User Mode Driver to it
  - program's reliability increased by removing error handlers caused
    infinite loops
  - now the program can be used in Windows Safe Mode when the user mode
    driver is enabled

  - since this version native 64-bit binaries aren't available
    due to the C compilers internal bugs (Windows DDK, Windows SDK, Pelles C,
    MinGW x64 were tested); portable UltraDefrag can be used now on all of the  
    64-bit systems instead of the native 64-bit packages

  - NOTE FOR PROGRAMMERS: to successfully compile the user mode driver run
    configure.lua script, check 'Apply patch to MinGW' box and click OK
    once again
