+Macro packages
+--------------

+* The m (mm) macro package's `IA` and `WA` macros--used only with the
+ "letter" document type configure by calling the `LT` macro--no longer
+ disables the escape character, and their counterparts `IE` and `WE`
+ no longer re�nable it. This change makes groff mm consistent with
+ DWB 3.3 mm. If you require the previous groff mm behavior, consider
+ writing and using wrapper macros such as the following in your
+ document.
+
+ .de iA
+ .IA
+ .eo
+ ..
+ .de iE
+ .ec
+ .IE
+ ..
+
+ These macro definitions are harmlessly redundant when formatting such
+ a document with an older version of groff mm.
