+  <code>go</code> <code>version</code></a> command now accepts arguments naming
+  executables and directories. When invoked on an executable,
+  <code>go</code> <code>version</code> prints the version of Go used to build
+  the executable. If the <code>-m</code> flag is used,
+  <code>go</code> <code>version</code> prints the executable's embedded module
+  version information, if available. When invoked on a directory,
+  <code>go</code> <code>version</code> prints information about executables
+  contained in the directory and its subdirectories.
