Release notes are available at: <a href="https://tip.golang.org/doc/go1.11" rel="nofollow">https://tip.golang.org/doc/go1.11</a><p>Headline features (as judged by me) are:<p>* A new WebAssembly backend, js/wasm, for the gc compiler.<p>* Preliminary support for modules, i.e., the first step towards a package manager built into the Go command.<p>* Improved support for debuggers, especially Delve.<p>* Removal of many direct system calls from the macOS runtime. Unlike on Linux, the macOS system call interface is not considered stable. Go 1.11 binaries are now less likely to break when you upgrade your macOS version because system calls are made through the proper channel (libc).
