Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
New config variable 'external-url'. Deep inside the import queue we don't known the URL we find the server at. We don't have any HTTP request we can derive this information wrong so it needs to be configured. Defaults to http://${web-host}:${web-port} .
