该版本主要是 bug 修复，另外 return 和 error_page 指令支持返回 307 重定向。
从 Nginx 的 CHANGES 记录中发现应该有不少的国人在为 Nginx 做一些改进。
修复的 bug 详细内容：
- 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.
- 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.
