- Cancelling Nyquist effects deleted unprocessed audio
- Change Speed and Change Tempo failed to modify the original selection length
- Cut lines invisible
- Fixed various bugs importing multi-stream files via FFmpeg
- File > Export as WAV could be corrupted if overwriting an imported WAV read direct from the file
- Export multiple "Other uncompressed files" choice always produced 16-bit PCM audio irrespective of chosen options.

- MP3 ID3 Genre tag misread on import if the genre list in Metadata Editor was opened and saved
- Exported metadata tags in MP3, OGG and FLAC often not seen by player software - now substantially improved

- Note: Windows users wanting to export MP3 files will require the latest version of the LAME encoder from http://lame.buanzo.com.ar/
