   A set of useful functions for use in TES5Edit scripts.
   
+  **IMPORTANT NOTE!**
+  As of 3/2/2015 a few functions were changed to have parameters passed by reference
+  instead of returning a new variable of the same type.  These functions were all
+  added recently so it shouldn't affect your scripts.  The affected functions are
+  listed below:
+  - [BatchCopyDirectory]: the batch stringlist is now passed by reference. Is now a 
+    procedure.
+  - [AddMastersToList]: the lst stringlist is now passed by reference. Is now a 
+    procedure.
+  - [SetChar]: the input string is now passed by reference. Is now a procedure.
+  
+  Other functions (such as ReverseString, RemoveFromEnd, and SanitizeFileName) weren't
+  changed for clarity regarding string operations.
+  
+  This note will be removed 4/2/2015.
+  
   **LIST OF INCLUDED FUNCTIONS**
   - [GetVersionString]: gets TES5Edit's version as a string.
   - [ColorToInt]: gets an integer value representing a color from a TColor record.
