+<pre>
+This weekly release includes improved support for testing.
+
+Memory and CPU profiling is now available via the gotest tool. Gotest will
+produce memory and CPU profiling data when invoked with the -test.memprofile
+and -test.cpuprofile flags. Run "godoc gotest" for details.
+
+We have also introduced a way for tests to run quickly when an exhaustive test
+is unnecessary. Gotest’s new -test.short flag in combination with the testing
+package’s new Short function allows you to write tests that can be run in
+normal or "short" mode; short mode is now used by all.bash to reduce
+installation time.
+The Makefiles know about the flag - you can just run "make testshort".
