-// Todo:
-//
-//   - seeking (note you can seek yourself using the pushdata API)
-//
 // Limitations:
 //
-//   - floor 0 not supported (used in old ogg vorbis files)
+//   - seeking not supported except manually via PUSHDATA api
+//   - floor 0 not supported (used in old ogg vorbis files pre-2004)
 //   - lossless sample-truncation at beginning ignored
 //   - cannot concatenate multiple vorbis streams
 //   - sample positions are 32-bit, limiting seekable 192Khz
 //       files to around 6 hours (Ogg supports 64-bit)
-// 
-// All of these limitations may be removed in future versions.

+//
+// Partial history:
+//    1.04    - 2014/08/27 - fix missing const-correct case in API
+//    1.03    - 2014/08/07 - warning fixes
+//    1.02    - 2014/07/09 - declare qsort comparison as explicitly _cdecl in Windows
+//    1.01    - 2014/06/18 - fix stb_vorbis_get_samples_float (interleaved was correct)
+//    1.0     - 2014/05/26 - fix memory leaks; fix warnings; fix bugs in >2-channel;
+//                           (API change) report sample rate for decode-full-file funcs
+//    0.99996 -            - bracket #include <malloc.h> for macintosh compilation
+//    0.99995 -            - avoid alias-optimization issue in float-to-int conversion
