 ** Other changes

-  - FIXME: format 2 still needs to be tweaked to allow complete ASCII
-  representation and to catch any more missing state; once 2.0 is released,
-  any further changes would introduce format 3.
+    additional state.  This includes the 'R' directive for default regular
+    expression syntax.  Also, a V2 file can now be represented completely
+    in ASCII, thanks to escape sequences.  Unfortunately, files frozen by
+    M4 1.4q that contain \ in macros cannot be read by 1.9b, but since 1.4q
+    was not widely distributed, this is not expected to be much of an
+    issue, and comes with the territory of using a beta release.

 FIXME: include the (long) list of changes in 1.4.x that were not already
   in earlier betas.
