PHREEQC: The Basic function DIFF_C returned an incorrect value at
temperatures other than 25 C. The value returned was missing a
factor TK/298.15, where TK is the current temperature in Kelvin. The
factor has now been added and the function returns the correct
value. Note that previous documentation indicated the returned
value was for 25 C, but the value returned is actually for the
current temperature of the system.
The return value for SETDIFF_C was also missing the factor TK/298.15.
This Basic function now returns the correct value for the current
temperature of the system (TK).
The Basic functions are provided only for user output, so all TRANSPORT
calculations used the correct temperature-dependent diffusion coefficients.

PHREEQC: Revised a bug fix from May 28, 2021 making Fe(+3) and Fe(3)
equivalent names in SELECTED_OUTPUT and Basic functions TOT and TOTMOL.
The previous fix had unintended consequences for element names like [Fe+3],
causing this definition to fail. The revised bug fix should eliminate the
unintended problem.
