 REVISION HISTORY
 ================
+v0.12.29 - 2021-04-02
+  - Fix a bug where the running PCM frame index is set to an invalid value when over-seeking.
+  - Fix a decoding error due to an incorrect validation check.
+
 v0.12.28 - 2021-02-21
   - Fix a warning due to referencing _MSC_VER when it is undefined.
