• fixed: alignment fault on some big-endian machines
• fixed: compiling with enable-mmx on gcc 4.3.x (thanks Joachim)
• improved: allow bitrate to be calculated for files down to 1/10 second
• improved: decoding of corrupt files (prevents heap overrun crashes)
• wavpack.exe (command-line encoder):

• added: genre display to info box (older Winamps)
• fixed: seek bar sometimes vacillates when moved
• fixed: crash when winamp is opened with files in playlist moved or deleted
• improved: hi-res audio now output as 24-bit (not 32-bit) for better compatibility (EQ, etc.)
• improved: performance of adding tracks to library, especially from network drives
• improved: decoding of corrupt files (prevents heap overrun crashes)
• cool_wv4.flt (CoolEdit / Audition filter):
• added: about box
• added: dynamic noise shaping for improved hybrid quality
• improved: display bitrate for files as short as 1/10 second
• improved: decoding of corrupt files (prevents heap overrun crashes)
• improved: replace "extra processing" switch with a slider (0-6)

Changes from v4.31 -> v4.40

• added: accepts long option names including --help for full usage info
• added: new hardware-friendly "high" mode that compresses almost as well as old "high" mode but decodes significantly faster; old "high" mode now available as "very high" (-hh)
• added: --optimize-mono option added to improve compression of mono material in stereo files (requires at least version 4.3 decoder)
• improved: "extra" mode levels 1-3 completely revamped, fast enough for use
• improved: switched to Microsoft Visual Studio 2005 (win32 only)
• removed: support for Windows 95
