- 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: dynamic noise shaping for improved hybrid quality
- added: --channel-order option to reorder nonconforming multichannel files
- added: --merge-blocks option to optimize storage of LossyWAV output files
- added: ignore -o on Windows for compatibility with Linux version

- added: full Unicode support for info box (older Winamps) and media library
- added: standard Winamp metadata display & edit for newer Winamps
- added: option to pass multichannel audio

- 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 to 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
