hg update weekly.<i>YYYY-MM-DD</i>
+This weekly snapshot includes some package changes.
+In preparation for the Go 1 package reorganziation the sources for various
+packages have been moved, but the import paths remain unchanged. This
+inconsistency breaks goinstall at this snapshot. If you use goinstall, please
+stay synced to the previous weekly snapshot until the next one is tagged.
+The Error methods in the html, bzip2, and sql packages that return error values
+have been renamed to Err.
+Some non-core parts of the http package have been moved to net/http/httputil.
+The Dump* and NewChunked* functions and ClientConn, ServerConn, and
+ReverseProxy types have been moved from http to httputil.
+The API for html/template is now a direct copy of the template API, instead of
+exposing a single Escape function. For HTML templates, simply use the
+html/template package as you would the template package.
