Version 1.3.2 2013-05-11
------------------------

New features:

- dataset label and type are now supported.  See write.xport() and
  read.xport() for examples.

Bug fixes:

- Integrate patch from foreign package to properly handle xport files
  with datasets that end exactly on an 80-byte record boundry & add
  corresponding test file.

- Replace file.path(path.package(...)) with system.file(...)

Changes:

- Remove oboslete .First.lib() function

- Replace file.path(path.package(...)) with system.file(...)

Version 1.3.1 2013-03-24
------------------------

Changes:

- Replace use of depreciated .path.package() with path.package() for R 3.0.0.

Version 1.3.0 2012-06-27
------------------------

New features:

- New function makeSASNames() to create valid and unique SAS names
  from character vectors.

Bug fixes:

- Improper handling of duplicates names in write.xport() was
  generating names longer than 8 characters, resulting in invalid
  files.  Corrected by using the new makeSASNames() function instead
  of the R make.names() function.


Version 1.2.4 2010-11-11
------------------------

Bug fixes:

- Fix bug in handling of 'as.is' argument to read.xport ('as.is=TRUE'
  was not operating as documented).


Version 1.2.3 2008-02-29
------------------------

Bug fixes:

- Fix typo in manual page for write.xport() reported by Yinlai Meng.


Version 1.2.2 2007-11-09
------------------------

Bug fixes:

-  Apply patches to fix problems on 64 bit platforms, as sumitted by
   Brian Ripley.


Version 1.2.1 2007-11-05
-------------------------

Other:

- Correct warning message due to extraneous ';' charcters after
  function closing braces.


Version 1.2.0 2007-11-01
-------------------------

New Features:

- SAS format and iformat information is now accessed via 'SASformat()'
  and 'SASiformat()' functions instead of 'formats' and 'iformat'.  The
  information accessed by these functions is now stored in attributes
  with the same name.  This avoids conflicts with the use of 'format'
  by chron objects.

- Copies of the code for foreign::read.xport and foreign::lookup.xport
  is now part of the SASxport package, permitting extension to these
  functions as needed, and removing the dependency on the foreign
  package.

- Overflow of SASxport numeric format values, which have a smaller
  range than IEEE 754 numeric values now standard,  now generates NAN
  instead of 0.0.


Bug Fixes:

- Fix for problem storing negative numbers.

- SAS format length and digit information is now properly captured
  by read.xport().  This is supported by an improved version of
  lookup.xport().

- SAS format information was not being properly utilized when more
  than one format was present.

- Improved handling of SAS date formats


Other:

- Test routines added to test handling of numeric values.


Version 1.1.1
-------------------------

-  Display support information at package startup


Version 1.1.0 -
-------------------------

New Features:

- Add support for autogeneration of SAS FORMAT information as a PROC
  CONTENTS fmtin= dataset.   This enables R factors to be handled
  properly on the receiving system.

Bug Fixes:


Other:

Bug fixes:

- Correct call to sprintf where printf was intended in src/ieee2ibm.c

Other:

- Augmented ieee2ibm code with corresponding ibm2ieee code for
  completeness.


Beta 2 - 2007-08-10
