nginx 1.0.13 *) Feature: the "return" and "error_page" directives can now 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: memory leaks. Thanks to Lanshun Zhou. *) Bugfix: nginx might log incorrect error "upstream prematurely closed connection" instead of correct "upstream sent too big header" one. Thanks to Feibo Li. *) Bugfix: on ZFS filesystem disk cache size might be calculated incorrectly; the bug had appeared in 1.0.1. *) Bugfix: the number of internal redirects to named locations was not limited. *) Bugfix: temporary files might be not removed if the "proxy_store" directive was used with SSI includes. *) Bugfix: in some cases non-cacheable variables (such as the $args variable) returned old empty cached value. *) Bugfix: the "proxy_redirect" directives might be inherited incorrectly. *) Bugfix: nginx could not be built with the ngx_http_perl_module if the --with-openssl option was used. *) Bugfix: nginx could not be built by the icc 12.1 compiler.
