1.3.14 is now the only version that supports Windows 7, Windows Vista and Mac OS X 10.4 to 10.7. Please upgrade to 1.3.14 if you are using Audacity 1.2 on those systems.

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).
