+<pre>
+This release includes changes to the exec package that will require changes
+to client code.
+
+The exec package has been re-designed with a more convenient and succinct API.
+This code:
+ args := []string{“diff”, “-u”, “file1.txt”, “file2.txt”}
+ p, err := exec.Run(“/usr/bin/diff”, args, os.Environ(), "",
+ exec.DevNull, exec.Pipe, exec.DevNull)
+ if err != nil {
+ return nil, err
+ }
+ var buf bytes.Buffer
+ io.Copy(&buf, p.Stdout)
+ w, err := p.Wait(0)
+ p.Close()
+ if err != nil {
+ return nil, err
+ }
+ return buf.Bytes(), err
+can be rewritten as:
+ return exec.Command(“diff”, “-u”, “file1.txt”, “file2.txt”).Output()
+See the exec package documentation for the details ("godoc exec").
+
+By setting the GOPATH environment variable you can use goinstall to build and
+install your own code and external libraries outside of the Go tree (and avoid
+writing Makefiles).
+See the goinstall command documentation for the details ("godoc goinstall").
