nginx 0.8.25

not found by $r->variable() method.
*) Feature: the ngx_http_degradation_module.
*) Feature: regular expression named captures.
*) Feature: now URI part is not required a "proxy_pass" directive if
variables are used.
*) Feature: now the "msie_padding" directive works for Chrome too.
*) Bugfix: a segmentation fault occurred in a worker process on low
memory condition; the bug had appeared in 0.8.18.
