nginx 1.1.16 *) Change: the simultaneous subrequest limit has been raised to 200. *) Feature: the "from" parameter of the "disable_symlinks" directive. *) Feature: the "return" and "error_page" directives can be used to return 307 redirections. *) Bugfix: a segmentation fault might occur in a worker process if the "resolver" directive was used and there was no "error_log" directive specified at global level. Thanks to Roman Arutyunyan. *) Bugfix: a segmentation fault might occur in a worker process if the "proxy_http_version 1.1" or "fastcgi_keep_conn on" directives were used. *) Bugfix: memory leaks. Thanks to Lanshun Zhou. *) Bugfix: in the "disable_symlinks" directive. *) Bugfix: on ZFS filesystem disk cache size might be calculated incorrectly; the bug had appeared in 1.0.1. *) Bugfix: nginx could not be built by the icc 12.1 compiler. *) Bugfix: nginx could not be built by gcc on Solaris; the bug had appeared in 1.1.15.
