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.
