Drupal 7.27 发布，此版本主要包括许多的 bug 修复，主要修复内容如下：
When pages are cached for anonymous users (either by Drupal or by an external system), the form state may leak between anonymous users.
As a consequence, there is a chance that interim form input recorded for one anonymous user (which may include sensitive or private information, depending on the nature of the form) will be disclosed to other users interacting with the same form at the same time.
This especially affects multi-step Ajax forms because the window of opportunity (i.e., the time span between user input and final form submission) is indeterminable.
Drupal是一个开源的内容管理系统(CMS) 平台，它是用PHP写成的。主要用于构造提供多种功能和服务的动态网站，这些功能包括用户管理(UserAdministration)、发布工作流 (Publishing Workflow)、讨论、新闻聚合(NewsAggregation)、元数据(Metadata)操作和用于内容共享的XML发布。Drupal有一 个优秀的模块化结构，提供了许多模块，包括短消息、个性化书签、网站管理、Blog、日记、电子商务、电子出版、留言簿、Job、网上电影院、论坛、投票 等模块。并且Drupal模块的下载、安装、定制非常方便。
