Changes with nginx 0.5.23 04 Jun 2007
*) Feature: the ngx_http_ssl_module supports Server Name Indication TLS
*) 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.
