New Features:

foo := [?]int {
	0 = 123,
	5..9 = 54,
	10..<16 = i*3 + (i-1)*2,
};

inline for x, i in 1..<4 {
	fmt.println(x, i);
}

foo :: proc(x: [$N]int) -> bool
	where N > 2 {
	fmt.println(#procedure, "was called with the parameter", x);
	return true;
}

Proper System V AMD64 Support on Darwin and Linux
Built-in Quaternions (Not just an April Fool's Joke any more)
- quaternion128 and quaternion256
Struct field tags

Foo :: struct {
	x: int    `tag1`,
	y: string `json:"y_field"`,
	z: bool, // no tag
};
