   II. IMPORTANT CHANGES
 
+    - Face metrics (face->size->metrics) and glyph metrics are no
+      longer rounded.  If you do not round in your applications too,
+      you may find glyphs become blurry.
+
     - A  new API  `FT_TrueTypeGX_Validate'  (in FT_GX_VALIDATE_H)  has
       been added to validate TrueType GX/ATT tables (feat, mort, morx,
       bsln, just, kern, opbd, trak,  prop).  After validation it is no
