nginx 0.8.42 *) Change: now nginx tests locations given by regular expressions, if request was matched exactly by a location given by a prefix string. The previous behavior has been introduced in 0.7.1. *) Feature: the ngx_http_scgi_module. Thanks to Manlio Perillo. *) Feature: a text answer may be added to a "return" directive.
