 Version @PHREEQC_VER@: @PHREEQC_DATE@
+	-----------------
+	August 23, 2025
+	-----------------
+	PHREEQC: Sulfate solubilities refit for phreeqc.dat, Amm.dat, and phreeqc_rates.dat.
+	
+	-----------------
+	August 5, 2025
+	-----------------
+	PHREEQC:  Added two options to SIT parameters: -EPSILON1 and -EPSILON2. The
+	total epsilon parameter for a pair of ions is calculated as 
+	epsilon + epsilon1*I + epsilon2*log10(I), where I is ionic strength.
+	
+	-----------------
+	July 24, 2025
+	-----------------
+	PhreeqcRM:  Isotopes were not included in the list of species generated by FindComponents. 
+	Added a calculation necessary to produce the correct list including isotopic species.
+	
+	-----------------
+	April 22, 2025
+	-----------------
+	PhreeqcRM:  Fixed test case AdvectBMI_py.py. The test case was incorrect and
+	did not advect calcium through the column. Replaced the concentration pointer
+	with explicit calls to get_value("Concentration", c) and set_value("Concentration", c)
+	to correct the problem. 
+	
+	-----------------
+	April 22, 2025
+	-----------------
+	PHREEQC:  Fixed MIX to allow negative mixing fractions.
