nginx 0.5.23 *) Feature: the ngx_http_ssl_module supports Server Name Indication TLS extension. *) Feature: the "fastcgi_catch_stderr" directive. Thanks to Nick S. Grechukh, OWOX project. *) Bugfix: a segmentation fault occurred in master process if two virtual servers should bind() to the overlapping ports. *) Bugfix: if nginx was built with ngx_http_perl_module and perl supported threads, then during second reconfiguration the error messages "panic: MUTEX_LOCK" and "perl_parse() failed" were issued. *) Bugfix: in the HTTPS protocol in the "proxy_pass" directive.
