-The closed function has been removed from the language. The syntax for channel receives has been changed to return an optional second value, a boolean value indicating whether the channel is closed. This code:
-v := <-ch
-if closed(ch) {

-It is now illegal to declare unused labels, just as it is illegal to declare unused local variables.

-The new gofix tool finds Go programs that use old APIs and rewrites them to use newer ones.  After you update to a new Go release, gofix helps make the necessary changes to your programs. Gofix will handle the http, os, and syscall package changes described below, and we will update the program to keep up with future changes to the libraries.

 * 5l, 6l, 8l: reduce binary size about 40% by omitting symbols for type, string, go.string.
