简单的说，Wordpress是一个BLOG程序，用它你可以架设完全属于你自己的BLOG。而Wordpress现在的应用又不仅仅只是在BLOG方面，因为其强大的扩展性，部分网站甚至已经开始使用Wordpress来架设，或者说这些BLOG你甚至都看不出它们只是BLOG而已了。

主要更新:
1. 原生Tag (标签) 支持
2. 升级通知功能
3. 规范了URL显示格式
4. 新的“所见即所得”编辑器

Native tagging support allows you to use tags in addition to categories on your post, if you so choose. We’ve included importers for the Ultimate Tag Warrior, Jerome’s Keywords, Simple Tags, and Bunny’s Technorati Tag plugins so if you’ve already been using a tagging plugin you can bring your data into the new system. The tagging system is also wicked-fast, so your host won’t mind.

Our new update notification lets you know when there is a new release of WordPress or when any of the plugins you use has an update available. It works by sending your blog URL, plugins, and version information to our new api.wordpress.org service which then compares it to the plugin database and tells you what the latest and greatest is you can use.

We’ve cleaned up URLs a bunch in a feature we call canonical URLs which does things like enforce your no-www preference, redirect posts with changed slugs so a link never goes bad, redirect URLs that get cut off in emails on similar to the correct post, and much more. This helps your users, and it also helps your search engine optimization, as search engines like for each page to be available in one canonical location.

Our new pending review feature will be great for multi-author blogs. It allows authors to submit a post for review by an editor or administrator, where before they would just have to save a draft and hope someone noticed it.
There is new advanced WYSIWYG functionality (we call it the kitchen sink button) that allows you to access some features of TinyMCE that were previously hidden.
