nginx 0.5.33 *) Change: now by default the "echo" SSI command uses entity encoding. *) Feature: the "encoding" parameter in the "echo" SSI command. *) Change: mail proxy was split on three modules: pop3, imap and smtp. *) Feature: the --without-mail_pop3_module, --without-mail_imap_module, and --without-mail_smtp_module configuration parameters. *) Feature: the "smtp_greeting_delay" and "smtp_client_buffer" directives of the ngx_mail_smtp_module. *) Feature: the "server_name" and "valid_referers" directives support regular expressions. *) Feature: the "server_name", "map", and "valid_referers" directives support the "www.example.*" wildcards. *) Bugfix: sub_filter did not work with empty substitution. *) Bugfix: in sub_filter parsing. *) Bugfix: a worker process may got caught in an endless loop, if the memcached was used. *) Bugfix: nginx supported low case only "close" and "keep-alive" values in the "Connection" request header line; bug appeared in 0.5.32. *) Bugfix: nginx could not start on Solaris if the shared PCRE library located in non-standard place was used.
