+Early termination
+-----------------
+
+If the math helper has a body then it stops rendering conditionals after the first conditional that returns true. Rendering an else block does not cause early termination, but else blocks are rendered.

@@ -7,6 +7,10 @@ Early termination
 
 Comparisons are done in-order and only the first matching comparison (eq/ne/gt/gte/lt/lte) is evaluated. All other non-comparison elements inside the select tag are still rendered normally.
 
+Matching is terminated even if the first matching comparison has its own key.
+
+Else blocks are rendered until the first matching comparison but else blocks after that are not rendered.

 Default vs none
 ---------------
 Default was deprecated as of dust 1.6.0 and no longer does anything. It was deprecated because it was essentially the same as none except that there could only be one per select block and it had to be placed after all the other conditions to make sure they were all false. None is more flexible.
