Nginx 的新版本发布非常快，几乎是三天一小变，五天一大变，刚刚发布的 0.7.44 版本新增了一些不错的特性，例如 proxy 模块的缓存，详细内容如下：
Changes with nginx 0.7.44 23 Mar 2009
*) Feature: the ngx_http_proxy_module preliminary cache support.
*) Feature: the --with-pcre option in the configure.
*) Feature: the "try_files" directive is now allowed on the server block level.
*) Bugfix: the "try_files" directive handled incorrectly a query string in a fallback parameter.
*) Bugfix: the "try_files" directive might test incorrectly directories.
*) Bugfix: if there is the single server for given address:port pair, then captures in regular expressions in a "server_name" directive did not work.
Changes with nginx 0.7.43 18 Mar 2009
*) Bugfix: a request was handled incorrectly, if a "root" directive used variables; the bug had appeared in 0.7.42.
