nginx-0.3.36-RELEASE import *) Feature: the ngx_http_addition_filter_module. *) Feature: the "proxy_pass" and "fastcgi_pass" directives may be used inside the "if" block. *) Feature: the "proxy_ignore_client_abort" and "fastcgi_ignore_client_abort" directives. *) Feature: the "$request_completion" variable. *) Feature: the ngx_http_perl_module supports the $r->request_method and $r->remote_addr. *) Feature: the ngx_http_ssi_module supports the "elif" command. *) Bugfix: the "\/" string in the expression of the "if" command of the ngx_http_ssi_module was treated incorrectly. *) Bugfix: in the regular expressions in the "if" command of the ngx_http_ssi_module. *) Bugfix: if the relative path was specified in the "client_body_temp_path", "proxy_temp_path", "fastcgi_temp_path", and "perl_modules" directives, then the directory was used relatively to a current path but not to a server prefix.
