### 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

a full C parser and type checker that was also aware of any extensions
known to the system compiler (for example, all the GNU C extensions) as
well as the system-specific header locations and system-specific
pre-#defined macros. This is certainly possible to do, but it is an
enormous amount of work.

Cgo takes a different approach. It determines the meaning of C
identifiers not by parsing C code but by feeding carefully constructed

		beginningOfLine: true,
		macros:          predefine(flags.D),

<p><!-- CL 461697 -->
  On macOS on 64-bit x86 architecture (the <code>darwin/amd64</code> port),
  the Go toolchain now generates position-independent executables (PIE) by default.
  Non-PIE binaries can be generated by specifying the <code>-buildmode=exe</code>
  build flag.
  On 64-bit ARM-based macOS (the <code>darwin/arm64</code> port),
  the Go toolchain already generates PIE by default.
