nginx 1.1.12 *) Change: a "proxy_pass" directive without URI part now uses changed URI after redirection with the "error_page" directive; Thanks to Lanshun Zhou. *) Feature: the "proxy/fastcgi/scgi/uwsgi_cache_lock", "proxy/fastcgi/scgi/uwsgi_cache_lock_timeout" directives. *) Feature: the "pcre_jit" directive. *) Feature: the "if" SSI command supports captures in regular expressions. *) Bugfix: the "if" SSI command did not work inside the "block" command. *) Bugfix: the "limit_conn_log_level" and "limit_req_log_level" directives might not work. *) Bugfix: the "limit_rate" directive did not allow to use full throughput, even if limit value was very high. *) Bugfix: the "sendfile_max_chunk" directive did not work, if the "limit_rate" directive was used. *) Bugfix: a "proxy_pass" directive without URI part always used original request URI if variables were used. *) Bugfix: a "proxy_pass" directive without URI part might use original request after redirection with the "try_files" directive; Thanks to Lanshun Zhou. *) Bugfix: in the ngx_http_scgi_module. *) Bugfix: in the ngx_http_mp4_module. *) Bugfix: nginx could not be built on Solaris; the bug had appeared in 1.1.9.
