- @Bind becomes @BindView and @BindViews (one view and multiple views, respectively).

- New: @BindArray binds String, CharSequence, and int arrays and TypeArray to fields.
- New: @BindBitmap binds Bitmap instances from resources to fields.
- @BindDrawable now supports a tint field which accepts a theme attribute.-The runtime and compiler are now split into two artifacts.
compile 'com.jakewharton:butterknife:8.0.0'
apt 'com.jakewharton:butterknife-compiler:8.0.0'- New: apply overloads which accept a single view and arrays of views.
- ProGuard rules now ship inside of the library and are included automatically.
- @Optional annotation is back to mark methods as being optional.
