WP官方发布了wordpress 3.3 rc 2版本，WP官方表示3.3 rc1版本倍受好倍，认为离最终版本发布的日子不长了，最新版的管理栏已经兼容所有浏览器，api接口也完善了；wp插件和wp主题作者请在最新版上面测试是否有兼容性问题，希望能在正式版之前修复。另外，要测试新版本的博主，请不要在正常运行的WP网站上测试。
wordpress官方博客原文：
The second release candidate for WordPress 3.3 is now available!
As the first release candidate was well-received, we think we’re really close to a final release. Primarily, we’ve ensured that new toolbar (the admin bar in 3.2) has a consistent appearance across all browsers, and the API for developers is now final. You can check our bug tracker for the complete list of changes.
Plugin and theme authors, please test your plugins and themes now, so that if there is a compatibility issue, we can figure it out before the final release. On our development blog, we’ve published a number of posts that explain important things you need to know as you prepare for WordPress 3.3.
If you haven’t tested WordPress 3.3 yet, now is the time — please though, not on your live site unless you’re adventurous. Once you install RC2, you can visit About WordPress page (hover over the WordPress logo in the top left) to see an overview of what’s to come in WordPress 3.3 (and what to test, of course).
If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums. Or, if you’re comfortable writing a reproducible bug report, file one on WordPress Trac. Known issues that crop up will be listed here.
Enjoy!
