Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Headers filter: added "add_trailer" directive. Trailers added using this directive are evaluated after response body is processed by output filters (but before it's written to the wire), so it's possible to use variables calculated from the response body as the trailer value.
