+ * flac since 1.9.1 (mixer needs libflac)
+ * mp3 since 1.9.1 (mixer needs libsmpeg/libmad; only use mad for GPL apps)
++  * Since 1.10.1 + mixer 2.0.2, mpg123 can also be used

++.. Note::

++    Sequenced format support changed with mixer v2.0.2. If mixer is

++    upported by both libraries, but if you were to try to load an
++    obscure format (like `apun` file with mikmod only), it will fail.

++    * Kivy <= 1.10.0: will fail to build with mixer >= 2.0.2
++      will report correct format support with < 2.0.2
++    * Kivy >= 1.10.1: will build with old and new mixer, and
++      will "guesstimate" sequenced format support
