   per the documentation on how grep's -w works.
 
   grep -i no longer mishandles patterns containing titlecase characters.
+  A pattern character now matches its lowercase and uppercase
+  counterparts, even when they both differ from the pattern.
   For example, in a locale containing the titlecase character
   'Lj' (U+01C8 LATIN CAPITAL LETTER L WITH SMALL LETTER J),
-  'grep -i Lj' now matches 'LJ' (U+01C7 LATIN CAPITAL LETTER LJ).
+  'grep -i Lj' now matches both 'LJ' (U+01C7 LATIN CAPITAL LETTER LJ)
+  and 'lj' (U+01C9 LATIN SMALL LETTER LJ).
