ColdFusion MX

When calculating a length, a
string-processing function
processes an ASCII 0 (NUL)
character and continues to
process subsequent
characters of the string, if any.
In ColdFusion 5, these
functions did not process any
subsequent characters of the
string after processing the
ASCII 0 (NUL) character.

ListSetAt

Change

ColdFusion MX

This function no longer
changes the first delimiter in
the list to the first delimiter
specified in the function.

Change

ColdFusion MX

In a descending sort with

textnocase

,

ListSort

returns

elements in a different order
than in ColdFusion 5.
