nginx 0.9.0
*) Feature: the "keepalive_disable" directive.
*) Feature: the "map" directive supports variables as value of a
defined variable.
*) Feature: the "map" directive supports empty strings as value of the
first parameter.
*) Feature: the "map" directive supports expressions as the first
parameter.
*) Feature: nginx(8) manual page.
Thanks to Sergey Osokin.
*) Feature: Linux accept4() support.
Thanks to Simon Liu.
*) Workaround: elimination of Linux linker warning about "sys_errlist"
and "sys_nerr"; the warning had appeared in 0.8.35.
*) Bugfix: a segmentation fault might occur in a worker process, if the
"auth_basic" directive was used.
Thanks to Michail Laletin.
*) Bugfix: compatibility with ngx_http_eval_module; the bug had
appeared in 0.8.42.
