- hgweb.config and the repositories can now exist in separate directories - error suppression when invalid absolute paths set - auto-insertion bug which re-added all folders in the repo directory on create/delete, even if not formally registered - blacklists creation of a repo derived from config 'base_url' instead of value "admin" where $config['base_url'] = http://www.contoso.com/hgadmin will blacklist "hgadmin" - missed translation items in hgdir controller - add the default /lock directory to source controll
