Release Name: 2.6.1

Notes:
== Rubygame 2.6.1

Release focus: Bug fixes.

=== Fixes

- Fixed: Rubygame::Mixer.open_audio was using a different default
  audio format than it did in 2.5.3, which caused an error on Mac.
  (Note: The Rubygame::Mixer.open_audio is deprecated, but kept for
  backwards compatibility. Use Rubygame.open_audio instead.)

- Fixed: Rubygame no longer tries to load audio features if SDL_mixer
  is not available. Trying to load them would cause an error, and
  didn't match the old behavior.
