There are 5 features, improvements and bug-fixes in this release.

• Conversion to AZW3 format
• Options to extract audio from video
• Improved document types classification
• Improved conversion from composite documents

To convert any of the supported file types to the AZW3 file type, just specify it in the Format property of the EBookConvertOptions class instance:

// Load the source PDF file
using (Converter converter = new Converter("sample.pdf"))
{
    // Set the convert options for AZW3 format
    var options = new EBookConvertOptions {
        Format = EBookFileType.Azw3
    };
    // Convert to AZW3 format
    converter.Convert("converted.azw3", options);
}

Extracting audio track from video is similar to converting video, however you need to set the ExtractAudioOnly property to true and specify the desired output format in the AudioFormat property:

// Load the source AVI file
VideoLoadOptions loadOptions = new VideoLoadOptions();
loadOptions.SetVideoConnector(new VideoConnector());
using (Converter converter = new Converter("sample_with_audio.avi", () => loadOptions))
{
    // Set the convert options
    VideoConvertOptions options = new VideoConvertOptions
    {
        ExtractAudioOnly = true,
        AudioFormat = AudioFileType.Ogg
    };
    // Convert to audio file
    converter.Convert("extracted_audio.ogg", options);
}
