nginx 0.8.29 *) Change: now the "009" status code is written to an access log for proxied HTTP/0.9 responses. *) Feature: the "addition_types", "charset_types", "gzip_types", "ssi_types", "sub_filter_types", and "xslt_types" directives support an "*" parameter. *) Feature: GCC 4.1+ built-in atomic operations usage. Thanks to W-Mark Kubacki. *) Feature: the --with-libatomic[=DIR] option in the configure. Thanks to W-Mark Kubacki. *) Bugfix: listen unix domain socket had limited access rights. *) Bugfix: cached HTTP/0.9 responses were handled incorrectly. *) Bugfix: regular expression named captures given by "?P<...>" did not work in a "server_name" directive. Thanks to Maxim Dounin.
