+#### 1.1.1

+- fixed parser miscalculates `duration` of `ANMF` chunk.
+  - If actual ANMF duration is 60(ms), parser reported duration as 61(ms), not 60.

 #### 1.1.0
 
 - Now `WebPInfo#parse`, `WebPInfo#isAnimated`, `WebPInfo#isLossless` methods can accept not only Buffer but also Local File Path, URL, and ReadableStream.
 
 
 #### 1.0.4
