What's new
==========

4.509 [2004.04.13]
~~~~~~~~~~~~~~~~~~
  - enhanced the WAV file parser to automatically detect uneven size
    chunks without the required alignment byte (non-conforming files)
  - slight general speed enhancement with around 2%
  - added the --headersize option to specify the starting header size
    for raw files, also useful for raw data alignment
  - enhanced the raw file parser to add the last few bytes to the tail
    instead of rejecting the file for having a non-divisible data size
  - enhanced automatic generation of file extension at decoding (using
    the header data to detect if the file is WAV or raw)
  - added full support for the data types SINT8, UINT16, UINT24, UINT32
  - fixed a very rare encoder bug where an invalid compressed block was
    created for some silence-like data. Thanks to Olivier for reporting

4.507 [2003.09.28]
~~~~~~~~~~~~~~~~~~
  - fixed wildcards support, where files not in the current directory
    were not expanded correctly with their path
  - fixed some small memory allocation problems
  - small fixes and improvements

4.506 [2003.05.31]
~~~~~~~~~~~~~~~~~~
  - added wildcards support for matching multiple source files
  - added the new highnew compression mode, 25% faster than extranew
    mode with very similar compression
  - the encoder now writes the exact compression mode used in the
    informational purpose field of the header (instead of just extra
    for the extranew mode)
  - added the --deleteafter option to delete the source file after
    successful encoding or decoding
  - added the --timestamp option to copy the source file's time stamp
    to the destination file when encoding or decoding
  - added the --md5 option to store MD5 hash of original raw PCM input
    data when encoding, and the --check command to check it later
  - made the --verify command work also silent
  - the --speedup option is now deprecated
  - fixed an important memory leak in the decoder common plug-in
    interface
  - fixed a rare decoder bug where files encoded with bestnew mode and
    speedup 1x would fail to decode. Thanks to Eltoder for reporting
  - small fixes and improvements

4.505 [2003.05.14]
~~~~~~~~~~~~~~~~~~
  - enabled compression to a pipe and decompression from a pipe
  - fixed a problem with rejection of some non-seekable raw input files
  - fixed a rare encoder problem with mono files and extranew mode
  - the ultra and insane compression modes are now deprecated
  - fixed crashing under Windows 95 due to SSE detection problem.
    Thanks to Case for reporting and help
  - small fixes and improvements
