Native Client (NaCl)

As announced in the Go 1.13 release notes, Go 1.14 drops support for the Native Client platform (GOOS=nacl).

Tools

TODO

Go command

The go command now includes snippets of plain-text error messages from module proxies and other HTTP servers. An error message will only be shown if it is valid UTF-8 and consists of only graphic characters and spaces.

The go get subcommand no longer accepts the -mod flag. Previously, the flag's setting either was ignored or caused the build to fail.
