Summary of Changes in 1.3.14:
- Bug fixes:
 - Fixes for data loss when encountering corrupted project files. Steps taken to prevent writing of overlong audio data block files.
 - Excessive delay occurred when typing into labels in long projects.
 - MP2 files could not be imported natively. File types requiring FFmpeg library imported as noise if FFmpeg was unavailable.
 - Crashes fixed when dragging tracks. Crash fixed when resetting Toolbars when an audio stream was present.
 - Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.
 
- Changes and Improvements:
 - Normalize now preserves left-right balance in stereo tracks by default with an option to normalize stereo channels independently.
 - Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
 - Mix and Render now preserves clip length by not rendering white space before the start of audio, and preserves audio before time zero.
 - CleanSpeech Mode has been removed from Preferences but can be run or disabled in 1.3.14 by changing Preferences in a previous Audacity version.
 - (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
