Changes in 1.3.2 (28 October 2006)
* Added support for writing compressed character classes, structures, cell arrays, and sparse arrays
* Added some tests to the test_mat program: write_compressed_cell, write_compressed_sparse
* Added 64-bit signed/unsigned integer support
* Fixed bugs in Reading slabs of N-dimensional data

Changes in 1.3.1 (7 Septempber 2006)
* Added some internal documentation to the library
* Defined two documentation groups public and internal
* Disabled the building of test programs by default and added a configure
  option to build them
* Fixed installation path of data and documentation
* Fixed bugs where file pointers were left open if allocating memory failed in Mat_Open and Mat_Create

Changes in 1.3.0 (30 June 2006)
* Cleaned out matio.h and made most preproccessor define's into enum's.
* Moved complex arrays from single pointer with real part followed by imaginary
  part to a struct with a pointer to the real part and a pointer to the
  imaginary part (Previous implementation was just plain ignorant).
* Changed version 4 mat file code from MAT_V4 to MAT_FT_MAT4 to match the
  version 5 identifier.
* Added function Mat_VarCalloc to allocate and initialize all fields of the
  matvar_t structure.
Bug Fixes in 1.3.0 (30 June 2006)
* WriteCompressedData did not initialize the data tag (data_tag variable).
* WriteStructField wrote the array name tag as a 2 byte integer followed by 2
  padding bytes. Correct implementation writes the array name tag as a 4 byte
  integer.
* Write5 wrote the array name tag as a 2 byte integer followed by 2
  padding bytes when the name was more than 4 characters. Correct
  implementation writes the array name tag as a 4 byte integer.
* Write5 had a hard-coded uncompressed variable size of 448 when writing
  compressed data.
* WriteInfo5 wrote the array name tag as a 2 byte integer followed by 2
  padding bytes when the name was more than 4 characters. Correct
  implementation writes the array name tag as a 4 byte integer.
* Mat_Create wrote the endian sequence incorrectly.
* Mat_VarCreate set the number of bytes incorrectly for structures.
* Mat_VarCreate fixed the data size of the character class to 1. That didn't
  allow for multi-byte characters.

Changes in 1.1.6 (20 March 2006)
* Added sparse class to compressed variable.
Bug Fixes in 1.1.6 (20 March 2006)
* Fixed release bug in reading double class data.
* Fixed various compressed variable writing bugs.
* Fixed a bug in Mat_VarCreate for sparse variables.

Changes in 1.1.4 (9 February 2006)
* Changed Licensing from the GNU General Public License to the GNU Lesser
  General Public License.
* Added support for reading numeric version 4 MAT files
* Added support for sparse datatypes other than double.  Although Matlab does
  not support these types, other free software does.
* Writing compressed variables is supported for Numeric arrays.  Future versions
  will implement character,sparse,cell, and structure arrays.
* A fortran 90/95 interface has been incorporated.  Not all functions are
  implemented yet, but more will come and it is at least functional now.
  Hopefully feedback will help guide the fortran interface development.
* Replaced preprocessor defines for types,classes,etc. with enum's.
Bug Fixes in 1.1.4 (9 January 2006)
* Mat_VarReadData did not handle complex data
