   - Change drwav_read_*() to allow NULL to be passed in as the output buffer which is equivalent to a forward seek.
+  - Fix a buffer overflow when trying to decode invalid IMA-ADPCM files.
+  - Add include guard for the implementation section.
 
 v0.12.5 - 2020-05-27
   - Minor documentation fix.
