+  I. IMPORTANT BUG FIXES
+
+    - If the library  was compiled on an i386  platform using gcc, and
+      compiler  option -O3 was  given, `FT_MulFix'  sometimes returned
+      incorrect  results   which  could  have   caused  problems  with
+      `FT_Request_Metrics'   and  `FT_Select_Metrics',   returning  an
+      incorrect descender size.
