Changes 1.8.10-patch1:
Library
-------
- The library now behaves correctly when performing large I/O operations on
  Mac OS-X.  Previously, single I/O operations > 2 GB would fail since the
  Darwin read/write calls cannot handle the number of bytes that their
  parameter types imply.
  Fixes HDFFV-7975 and HDFFV-8240 (DER - 07 JAN 2013)
- Fixed a bug in the core VFD that cause failures when opening files > 2 GB.
  Fixes HDFFV-8124 and HDFFV-8158 (DER - 07 JAN 2013)
Tools
-----
- The following h5stat test case failed in BG/P machines (and potentially
  other machines that display extra output if an MPI task returns with a
  non-zero code.)
    Testing h5stat notexist.h5
  The test script was fixed to ignore the extra output.
  HDFFV-8233 (AKC - 2012/12/17)
- h5diff: Fixed slowness when comparing HDF5 files with many attributes.
  Much slower performance was identified with later release version
  (from 1.8.7 to 1.8.10) compared to 1.8.6. The issue was introduced
  from fixing an attribute related bug for 1.8.7 release in the past.
