nginx 0.6.25
*) Change: now the "server_name_in_redirect" directive is used instead
of the "server_name" directive's special "*" parameter.
*) Change: now wildcard and regex names can be used as main name in a
"server_name" directive.
*) Change: the "satisfy_any" directive was replaced by the "satisfy"
directive.
*) Workaround: old worker processes might hog CPU after reconfiguration
if they was run under Linux OpenVZ.
*) Feature: the "min_delete_depth" directive.
*) Bugfix: the COPY and MOVE methods did not work with single files.
*) Bugfix: the ngx_http_gzip_static_module did not allow the
ngx_http_dav_module to work; bug appeared in 0.6.23.
*) Bugfix: socket leak in HTTPS mode if deferred accept was used.
Thanks to Ben Maurer.
*) Bugfix: nginx could not be built without PCRE library; bug appeared
in 0.6.23.
