     * New value 2 for use_fixed_qp_offsets: disallow the application of
       per-frame QP offsets, enabling full control of each frame's QP, by
       adjusting rc_cfg.cq_level between each encoded frame.
-    * Low-complexity mode support is extended to VOD encoding.
+    * Low complexity decode mode (the encoder optimizations that produce
+      encoded bitstreams that can be decoded at low computational
+      complexity) now supports good-quality encoding (speed 1 to 3) for

     * New AOM_EFLAG_FREEZE_INTERNAL_STATE flag for aom_codec_encode() to
