+	PHREEQC: Added the ColdChem.dat database developed by Toner and
+	Catling, Journal of Chemical & Engineering Data, 2017, DOI: 10.1021/
+	acs.jced.6b00812. It is a comprehensive Pitzer model in the Na-K-Ca-Mg-
+	Cl system valid for low temperature, from 298.15 to < 200 K.
+	PHREEQC was modified to allow definition of the temperature dependence
+	of A(phi) in the Pitzer formulation through a new option, -APHI, in 
+	the PITZER keyword. The coefficients of the APHI expression are the
+	same as the temperature dependence of other Pitzer parameters.
+	A new Basic function, APHI, has been added to give the value of 
+	the parameter in the current calculation.

+	PHREEQC: Error check that the same element name was not used for
+	both a SURFACE and and EXCHANGEr, which caused a NULL pointer. Some variables in the unknown
+	structure are now initialized.
