+* Upgrade to Go 1.18.0
+
+    Binary executables for this version are now published with Go version 1.18.0. The [Go release notes](https://go.dev/doc/go1.18) say that the linker generates smaller binaries and that on 64-bit ARM chips, compiled binaries run around 10% faster. On an M1 MacBook Pro, esbuild's benchmark runs approximately 8% faster than before and the binary executable is approximately 4% smaller than before.
