nginx 1.1.15
*) Feature: the "disable_symlinks" directive.
*) Feature: the "proxy_cookie_domain" and "proxy_cookie_path"
directives.
*) Bugfix: nginx might log incorrect error "upstream prematurely closed
connection" instead of correct "upstream sent too big header" one.
Thanks to Feibo Li.
*) Bugfix: nginx could not be built with the ngx_http_perl_module if the
--with-openssl option was used.
*) Bugfix: internal redirects to named locations were not limited.
*) Bugfix: calling $r->flush() multiple times might cause errors in the
ngx_http_gzip_filter_module.
*) Bugfix: temporary files might be not removed if the "proxy_store"
directive were used with SSI includes.
*) Bugfix: in some cases non-cacheable variables (such as the $args
variable) returned old empty cached value.
*) Bugfix: a segmentation fault might occur in a worker process if too
many SSI subrequests were issued simultaneously; the bug had appeared
in 0.7.25.
