A lot of things went down since the last release. I sort of left out creating new releases until I realized things like the AUR package where using the old 0.6.1 release. Will try to create releases regularly from now if there are changes.

Braking changes

• Reworked noncurses output mode and made it defualt.

  The reworked noncurses mode uses a custom framebuffer technique that only draws changes per frame and only writes to the terminal once per frame. This results in far less cpu usage then ncurses. It is also free of the flickering that we see in ncurses mode #196

  Colors are no longer set by default so hopefully cava will change color automatically in noncurses mode when using tools such as pywall #340 #181

  Unfortunately html colors, gradient and key controls are not supported in noncurses.

Other improvements:

• separated bass, midtones and treble in to separate fftw operations
