hg update weekly.<i>YYYY-MM-DD</i>
+This weekly contains some package re-shuffling. Users of the http and
+template packages may be affected.
+This weekly replaces the template package with exp/template.
+The original template package is still available as old/template.
+The old/template package is deprecated and will be removed at some point
+in the future. The Go tree has been updated to use the new template package.
+We encourage users of the old template package to switch to the new one.
+Code that uses template or exp/template will need to change
+its import lines to "old/template" or "template", respectively.
+The http package's URL parsing and query escaping code (such as ParseURL and
+URLEscape) has been moved to the new url package, with several simplifications
+to the names. Client code can be updated automatically with gofix.
