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.
