-I haven't updated the Windows installer in a while because I introduced the
-ability to access mpmath's plotting component in 6.2.0.  However, this means I
-need to bring a metric ton of more libraries for the Windows installer.
-
-I haven't decided how to address that because the plotting functionality is
-very elementary at this point.  I hate the idea of bloating up the install with
-tons of stuff for a feature that is of peripheral utility (outside of high
-school algebra homework).

-On the other hand, there have been some important bug fixes recently, and more

 Release Notes:
 
+6.2.0
+
+Experimental support for mpath plotting functionality using the new
+operators, 'plot', 'plot2', 'plotc'.  These operators are not supported
+in the Windows installer.
+
+'quit' is now an alias for 'exit' in interactive mode and help mode.
+
+Improvements in function definition.  'y' and 'z' are now operators, allowing
+for defining functions on 2 or 3 variables.
+
+Operators 'eval2' and 'eval3' allow for evaluation of 2 and 3 variable
+operators.
+
+rpn now throws an error if a user-defined function is invalidly specified,
+instead of going into an infinite loop.
+
+'filter' allows filtering a list based on a user-defined function.
+
+If the units in a measurement cancel out, then the measurement is converted
+back to a numerical value.
+
+Added 'rand_' and 'randint_' operators.
+
+Added the 'debruijn' operator.
+
+Fixed several minor bugs.
+
 6.1.0
 
 New operators:  'maxdouble', 'maxfloat', 'mindouble', 'minfloat'
