 REVISION HISTORY
 ================
 v0.10.5 - TBD
+  - Change ma_zero_pcm_frames() to take a 64-bit frame count.
   - Add MA_NO_GENERATION build option to exclude the `ma_waveform` and `ma_noise` APIs from the build.
   - Add support for formatted logging to the VC6 build.
   - Minor documentation updates.
