### Darwin {#darwin}

<!-- go.dev/issue/64207 -->
As [announced](go1.22#darwin) in the Go 1.22 release notes,
Go 1.23 requires macOS 11 Big Sur or later;
support for previous versions has been discontinued.

### Wasm {#wasm}

<!-- go.dev/issue/63718 -->
The `go_wasip1_wasm_exec` script in `GOROOT/misc/wasm` has dropped support

# Special cases

A few special C types which would normally be represented by a pointer
type in Go are instead represented by a uintptr. Those include:

1. The *Ref types on Darwin, rooted at CoreFoundation's CFTypeRef type.

2. The object types from Java's JNI interface:

	jobject
	jclass
	jthrowable
	jstring
	jarray
	jbooleanArray
	jbyteArray
	jcharArray

line := Line{origin, Point3D{y: -4, z: 12.3}}  // zero value for line.q.x
</pre>

<p>
For array and slice literals the following rules apply:
</p>
<ul>
	<li>Each element has an associated integer index marking
	    its position in the array.
	</li>
	<li>An element with a key uses the key as its index. The
	    key must be a non-negative constant
