nginx 0.7.9 *) Change: now ngx_http_charset_module works by default with following MIME types: text/html, text/css, text/xml, text/plain, text/vnd.wap.wml, application/x-javascript, and application/rss+xml. *) Feature: the "charset_types" and "addition_types" directives. *) Feature: now the "gzip_types", "ssi_types", and "sub_filter_types" directives use hash. *) Feature: the ngx_cpp_test_module. *) Feature: the "expires" directive supports daily time. *) Feature: the ngx_http_xslt_module improvements and bug fixing. Thanks to Denis F. Latypoff and Maxim Dounin. *) Bugfix: the "log_not_found" directive did not work for index files tests. *) Bugfix: HTTPS connections might hang, if kqueue, epoll, rtsig, or eventport methods were used; the bug had appeared in 0.7.7. *) Bugfix: if the "server_name", "valid_referers", and "map" directives used an "*.domain.tld" wildcard and exact name "domain.tld" was not set, then the exact name was matched by the wildcard; the bugs had appeared in 0.3.18.
