nginx 0.4.0 *) Change in internal API: the HTTP modules initialization was moved from the init module phase to the HTTP postconfiguration phase. *) Change: now the request body is not read beforehand for the ngx_http_perl_module: it's required to start the reading using the $r->has_request_body method. *) Feature: the ngx_http_perl_module supports the DECLINED return code. *) Feature: the ngx_http_dav_module supports the incoming "Date" header line for the PUT method. *) Feature: the "ssi" directive is available inside the "if" block. *) Bugfix: a segmentation fault occurred if there was an "index" directive with variables and the first index name was without variables; bug appeared in 0.1.29.
