Changes between 0.9.9 and Nightly Builds

    Core
      - Removed mcdeint deinterlace and decomb modes. This relied on the snow encoder in libav which has been was removed by upstream.
      - Intel QuickSync Video Encode / Decode support.
      - DXVA Hardware Decode support (Windows Only). Note this is only suitable for slower machines.
      - OpenCL Bicubic Scaling. (Lanzos is the default software scaler. Bicubic OpenCL scaler is available for those with OpenCL 1.1 or later compatible graphics cards)
      - Denoise filter now accepts individual settings for both chroma channels (Cr, Cb)
      - Presets
         + Added Windows Phone 8 Preset
      - Updated Libraries
         + x264 r2377-1ca7bb9
      - Libavformat is now used for muxing instead of mp4v2 and libmkv
         + The LibAV AAC encoder is now the default as FAAC has been removed.
           This encoder is adequate for most, but until it improves a bit further, we have enabled support for the FDK-AAC encoder also.
           This FDK option is a temporary measure until the LibAV encoder improves.
           Note that FDK-AAC is much slower and will likely bottleneck the encode process, but will produce better quality audio.
    Windows
      - Added option to 'Use System Colors'
         + This disables some of the custom app styling which should make it more suitable for those running in Accessibility mode or custom themes on Windows.
      - LibHB is now used for scanning instead of the CLI.
      - Improved the layout and design of the Audio and Subtitle tabs.
         + Split buttons similar to the old WinForms? GUI
         + Improved layout on the track listbox to make better use of the space.
      - Autoname Destination files
         + Added option to remove common punctuation (Dash(-), Period(.) and Comma(,)
         + Added Quality and Bitrate as placeholder options.
      - When Done
         + Added an option that will reset this to 'Do nothing' when the app is closed and restarted.
      - Presets
         + New 'Presets' Menu
         + Presets bar can now be hidden if it's not wanted.
      - Numerous bug fixes
         + Fixed the Issue in the source dropdown where the drive menu items did not work when clicked.
         + Numerous fixes in the Picture settings panel around resolution calculation.
         + Numerous fixes around the way Presets are loaded and saved, particularly around Picture settings.

                 -bf 2 -trellis 2 becomes bf=2:trellis=2

    -> Audio:

       - audio gain control (increase/decrease audio volume)

       - updated libogg (1.3.0) and libvorbis (aoTuV b6.03)
       - new AAC encoder (from libavcodec) (considered experimental)
         (supported mixdowns: Mono/Stereo/Dolby, 5.1 will come later)
         (should be on par with faac in terms of quality, sometimes better)
       - FLAC encoder (16-bit, MKV container only)

       - Mac OS X: HE-AAC encoding support, via Core Audio

       - quality-based variable bitrate encoding support
         works with: Lame MP3, Vorbis, Core Audio AAC
         only implemented in CLI and Linux GUI

       - AC3 encoder: set Dolby Surround flag in stream parameters when mixdown is Dolby Surround or Pro Logic II

    - Nested presets
    - Individual activity logs for each encode
    - Allows pending queue items to be removed, and reloaded in the main window for editing
    - Better handling of HD previews
    - Assorted other improvements

    CLI
    - Updated presets to the equivalent of the nested ones in the GUIs
    - Allows setting custom audio track names in MP4 files
    - Allows selection of the COLR atom in MP4 files, between Bt.601 and Bt.709
    - Fixed reading of device paths in OS X

    A special note on the new presets (they're collapsible-triangle-folder-thing-errific!)
    - Deux Six Quatre, Blind, Broke, and Bedlam are gone. They were dead weight.
    - iPod Low-Rez is now iPod Classic & iPod Nano
    - iPod High-Rez is now iPod Legacy
    - iPhone / iPod Touch is now iPhone & iPod Touch, so take care CLI users
    - Animation and Television now use the decomb and detelecine (VFR) filters
    - High Profile presets now use psy-trellis and the new subme 9 mode with B-frame RD refinement
    - AppleTV is now CRF, so sizes will vary with content
    - PS3 preset should be fixed
    - Constant Quality Rate still needs its quality % lowered, probably

    The keen reader is already asking "iPod Legacy? WTF is iPod High-Rez called iPod Legacy now?"

    The answer is Universal.

    The Universal preset is designed to play on all modern iPods (anything newer than the iPod 5.5G). It also plays on iPhones. It also plays on AppleTVs. It should also play just about anywhere else, hence the name. It is full anamorphic DVD resolution--no tricks with downscaling like stuff from the iTunes Store. It includes chapters, and has the first audio track in both AAC (DPL2 downmixed) and AC3 pass-thru, just like the AppleTV preset. In fact, it should give the same quality as the AppleTV preset, but faster...and at a larger file size. Like the AppleTV preset, it used CRF, so sizes will vary.

0.9.3 Snapshot2 -> 0.9.3 Snapshot 3 (r1797)
    Core Library:
    - Universal input support, utilizing libavcodec from the FFmpeg project for decoding non-MPEG-2 video

    - More accurate auto-cropping
    - Support for New Zealand and Norwegian HDTV broadcasts (H.264 and AAC-LATM in MPEG-TS)

    - Threaded and entirely rewritten decomb filter
    - Better audio resampling interpolator
