     CHANGES
     ~~~~~~~
     0.9.0 -- original version.
  
     0.9.0a/b -- no changes in this file.
  
     0.9.0c
        * made zero-length BZ_FLUSH work correctly in bzCompress().
        * fixed bzWrite/bzRead to ignore zero-length requests.
        * fixed bzread to correctly handle read requests after EOF.
        * wrong parameter order in call to bzDecompressInit in

  	bzBuffToBuffDecompress.  Fixed.

  "

  "

  "

  "

  "

  "

        "* If the error cannot be reproduced, and/or happens at different
  "
        "  points in compression, you may have a flaky memory system.
  "
        "  Try a memory-test program.  I have used Memtest86
  "
        "  (www.memtest86.com).  At the time of writing it is free (GPLd).
  "
        "  Memtest86 tests memory much more thorougly than your BIOSs
  "
        "  power-on test, and may find failures that the BIOS doesn't.
