Version Published Release Notes
1.4.0.0

Corrected serious unit conversion error in viscosity.
1.3.0.0

Corrected code for downloading data, according to the comment by Martijn van Heumen.
1.2.0.0

For Matlab versions older that R2017b, I now use Python (2.7 or 3.x) as a workaround to read the secure (https) web pages from NIST. See the readme.txt file for details. I welcome feedback on how this works for you!
1.1.0.0

nistdata ceased to work after NIST upgraded to the https protocol. I have updated the file so that it will hopefully work in Matlab 2017b and later, but my Matlab licence is too old to test this.
