<h3 id="goroot">Moved GOROOT</h3>
<p><!-- CL 42533 -->
The <a href="/cmd/go/">go tool</a> will now use the path from which it
was invoked to attempt to locate the root of the Go install tree.
This means that if the entire Go installation is moved to a new
location, the go tool should continue to work as usual.
This may be overriden by setting <code>GOROOT</code> in the environment,
which should only be done in unusual circumstances.
Note that this does not affect the result of
the <a href="/pkg/runtime/#GOROOT">runtime.GOROOT</a> function, which
will continue to report the original installation location;
this may be fixed in later releases.
