+    Previous implementations of /usr/bin/sed had unspecified behaviour
+    if multibyte characters are encountered. The old behaviour can
+    be emulated by invoking sed with LC_ALL=C sed <options>.
+
+    Previous implementations of /usr/bin/sed used the regexp(5) API
+    and /usr/xpg4/bin/sed used the regex(5) API. The new
+    implementation of /usr/bin/sed uses the regex(5) API in a
+    lenient regular expression interpretation mode to ensure
+    backwards compatibility.
