Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added 'type' attribute to <dc:variable/> element. If an optional 'type' attribute is given the result of the XPATH expression is interpreted as this type. Valid values are 'number', 'bool', 'node' and 'nodeset'. All other defaults to 'string' which also is the default if nor type is given.
