0.8.1
Monday, 15 October 2007
-----------------------

General
- Added some test cases to check viscosity correlation in test.py

- Fixed bug in isinfnan.h (missing #include <math.h>), with thanks to
  Bruna Abreu Calfa.

0.8
Friday, 21 September 2007
-------------------------

General:
- Fixed errors in the conductivity correlation.
- Some methods in steamcalculator.h have had their parameters changed.

0.7.2
Sunday, 19 August 2007
----------------------

General:
- libfreesteam is now a shared library/DLL.

For Windows users:
- ASCEND hook DLL renamed to freesteam_ascend.dll for use with
  current ASCEND (0.9.5.113 and newer)
- Static library has been changed to a shared library (DLL) on Windows
  to reduce duplication of code between Python module and core DLL.

- Various improvements to RPM packaging.
- Improved detection of ASCEND at compile-time.

Thursday, 18 January, 2007
--------------------------
