We are not aware of the version number or release date for either format. Bio-Formats uses the `JAI Image I/O Tools `_ library to read ND2 files compressed with JPEG-2000. There is also a **legacy** ND2 reader that uses Nikon's native libraries. To use it, you must be using Windows 32-bit and have `Nikon's ND2 reader plugin for ImageJ `_ installed. Additionally, you will need to download :source:`LegacyND2Reader.dll ` and place it in your ImageJ plugin folder. Note that this reader is **unmaintained** and no additional support effort will be made.
