CHANGELOG

-2015-11-09 v1.5.0 "Javan Whistling Duck"
-  This release improves upon the VP9 encoder and speeds up the encoding and
-  decoding processes.
-
-  - Upgrading:
-    This release is ABI incompatible with 1.4.0. It drops deprecated VP8
-    controls and adds a variety of VP9 controls for testing.
-
-    The vpxenc utility now prefers VP9 by default.
-
-  - Enhancements:
-    Faster VP9 encoding and decoding
-    Smaller library size by combining functions used by VP8 and VP9
-
-  - Bug Fixes:
-    A variety of fuzzing issues
+xxxx-yy-zz v1.4.0 "Changes for next release"
+  vpxenc is changed to use VP9 by default.
+  Encoder controls added for 1 pass SVC.
+  Decoder control to toggle on/off loopfilter.
 
 2015-04-03 v1.4.0 "Indian Runner Duck"
   This release includes significant improvements to the VP9 codec.
