Changes in 1.3.4 (30 March 2010)
 * Fix a read error. Closes bug #2899113
 * Fix a bug on sparse complex matrices.
 Note that these bug fixes and release have been handled by Vincent Couvert 
 and Sylvestre Ledru (both from Scilab) with the agreement of Christopher
 Hulbert 

Changes in 1.3.3 (02 June 2008)

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
