+ + Go 1.12 is not yet released. These are work-in-progress + release notes. Go 1.12 is expected to be released in February 2019. + +
+ ++ The latest Go release, version 1.12, arrives six months after Go 1.11. + Most of its changes are in TODO. + As always, the release maintains the Go 1 promise of compatibility. + We expect almost all Go programs to continue to compile and run as before. +
+ ++ There are no changes to the language specification. +
+ +
+ The build cache is now required as a step toward eliminating
+ $GOPATH/pkg. Setting the environment variable
+ GOCACHE=off to disable the
+ build cache
+ has no effect in Go 1.12.
+
+ In Go 1.12, godoc no longer has a command-line interface and
+ is only a web server. Users should use go doc
+ for command-line help output instead.
+
+ All of the changes to the standard library are minor. +
+ ++ As always, there are various minor changes and updates to the library, + made with the Go 1 promise of compatibility + in mind. +
