nginx 0.1.14 *) Feature: the autoconfiguration directives: --http-client-body-temp-path=PATH, --http-proxy-temp-path=PATH, and --http-fastcgi-temp-path=PATH *) Change: the directory name for the temporary files with the client request body is specified by directive client_body_temp_path, by default it is <prefix>/client_body_temp. *) Feature: the ngx_http_fastcgi_module and the directives: fastcgi_pass, fastcgi_root, fastcgi_index, fastcgi_params, fastcgi_connect_timeout, fastcgi_send_timeout, fastcgi_read_timeout, fastcgi_send_lowat, fastcgi_header_buffer_size, fastcgi_buffers, fastcgi_busy_buffers_size, fastcgi_temp_path, fastcgi_max_temp_file_size, fastcgi_temp_file_write_size, fastcgi_next_upstream, and fastcgi_x_powered_by. *) Bugfix: the "[alert] zero size buf" error; bug appeared in 0.1.3. *) Change: the URI must be specified after the host name in the proxy_pass directive. *) Change: the %3F symbol in the URI was considered as the argument string start. *) Feature: the unix domain sockets support in the ngx_http_proxy_module. *) Feature: the ssl_engine and ssl_ciphers directives.
