WordPress is the world’s most popular Content Management System. *(Some will argue it’s not a CMS. To them, I say: WordPress is a System for Managing Content — stop being persnickety!)* Reasons for its colossal success include:

WordPress是世界上最受欢迎的内容管理系统。 *(有人会说这不是CMS。对他们来说，我说：WordPress是一个用于管理内容的系统-别太讨厌！)*其巨大成功的原因包括：

*  WordPress is free.
    
    WordPress是免费的。
 *  It’s easy to install, use and extend. Novice developers and content editors have a shallower learning curve than similar products.
    
    它易于安装，使用和扩展。 新手开发商和内容编辑者的学习曲线要比同类产品浅。
 *  There are plugins and themes to suit every requirement.
    
    有适合所有需求的插件和主题。
 *  An active community means support and development resources are easier to find than most software.
    
    活跃的社区意味着比大多数软件更容易找到支持和开发资源。

WordPress adoption has reached critical mass. Other systems may be prettier or have a more elegant code base, but it’s difficult to recommend an alternative when WordPress is so ubiquitous.

WordPress的采用已达到临界点。 其他系统可能更漂亮或更具有优雅的代码库，但是当WordPress如此普及时，很难推荐一个替代方案。

[WordPress 3.9][] was released on April 16, 2014. It’s a major release so your existing installations won’t auto-update; you’ll need to log in and follow the update instructions. Plugin and theme incompatibility is rare, but you should back-up and investigate further before starting. You have backed up, haven’t you?

[WordPress 3.9][]于2014年4月16日发布。这是一个主要版本，因此您现有的安装不会自动更新。 您需要登录并按照更新说明进行操作。 插件和主题不兼容的情况很少见，但是您应该备份并进一步调查，然后再开始。 您已经备份了，不是吗？

What can users and developers expect from version 3.9?…

用户和开发人员从3.9版可以期待什么？…

## 缩小编辑和发布之间的差距 **(**Closing the Gap Between Editing and Publishing**)** ##

Content editing is more advanced than previous editions:

内容编辑比以前的版本更高级：

*  Images can be dragged to the editor, cropped, rotated, and resized.
    
    可以将图像拖到编辑器中，进行裁剪，旋转和调整大小。
 *  Gallery previews appear in the editing window.
    
    图库预览显示在编辑窗口中。
 *  The “distraction-free” writing mode is responsive and scales to any screen size.
    
    “无干扰”书写模式具有响应能力，可缩放至任何屏幕尺寸。
 *  Live widget and header image previews are available in the Customizer.
    
    定制器中提供实时窗口小部件和标题图像预览。
 *  TinyMCE has been updated to version 4.0.
    
    TinyMCE已更新至版本4.0。

Content editors have more sophisticated controls and the inevitable cutting-and-pasting from Microsoft Word will lead to fewer issues. *In theory*. In my experience, users trash a lovingly-created site within three seconds of gaining access. It doesn’t matter what safeguards you put in place — they’ll find a way to insert a 5Mb image or fill the page with impenetrable HTML. I often wish WordPress would switch to markdown syntax like [Ghost][] — but few content editors will agree.

内容编辑器具有更复杂的控件，Microsoft Word中不可避免的剪切和粘贴操作将导致更少的问题。 *从理论上讲* 。 以我的经验，用户在获得访问权限后三秒钟之内便将一个精心创建的网站删除。 不管您采用什么保护措施-他们都会找到一种方法来插入5Mb图像或使用难以渗透HTML填充页面。 我经常希望WordPress会切换到[Ghost之][Ghost]类的markdown语法-但很少有内容编辑会同意。

## 主题浏览器 **(**Theme Browser**)** ##

WordPress 3.9 features a new theme browser which allows you to preview and install new layouts in a couple of clicks:

WordPress 3.9具有一个新的主题浏览器，您可以通过单击几下预览和安装新的布局：

A powerful filter and search form allows you to define a theme to match your mood:

功能强大的过滤器和搜索表单使您可以定义主题以匹配您的心情：

## 音频和视频播放列表 **(**Audio and Video Playlists**)** ##

You’re no longer limited to image-only galleries: users can create their own audio and video playlists within WordPress 3.9. Media files added to the library can be organized and inserted into the page using a shortcode in the same way as any other gallery. WordPress will even fetch song cover thumbnails for MP3 files containing appropriate ID3 tags.

您不再局限于纯图像画廊：用户可以在WordPress 3.9中创建自己的音频和视频播放列表。 可以使用简码来组织添加到库中的媒体文件，并将其插入页面中，方法与任何其他库一样。 WordPress甚至会为包含适当ID3标签的MP3文件获取歌曲封面缩略图。

## 开发人员更新 **(**Developer Updates**)** ##

Several new features have been added for theme and plugin developers. At the time of writing, documentation is fairly minimal — *if not non-existent* — but the most interesting new functions are:

为主题和插件开发人员添加了一些新功能。 在撰写本文时，文档非常少( *即使不存在)* ，但是最有趣的新功能是：

*  `wp_get_playlist()`, `wp_playlist_shortcode()`, and `wp_video_playlist_shortcode()` functions permit control over playlists. In addition, WordPress now uses HTML5 for gallery and playlist controls.
    
    `wp_get_playlist()` ， `wp_playlist_shortcode()`和`wp_video_playlist_shortcode()`函数允许控制播放列表。 此外，WordPress现在将HTML5用于图库和播放列表控件。
 *  `has_image_size()` and `remove_image_size()` join the `add_image_size()` function and allow fine control over image resizing.
    
    `has_image_size()`和`remove_image_size()`加入`add_image_size()`函数，并可以很好地控制图像的大小调整。
 *  New `post_supports_thumbnails()` and `theme_supports_thumbnails()` functions.
    
    新的`post_supports_thumbnails()`和`theme_supports_thumbnails()`函数。
 *  New `doing_filter()` and `doing_action()` functions identify hooks in progress.
    
    新的`doing_filter()`和`doing_action()`函数标识正在进行的钩子。
 *  Multi-site WordPress installations can now use `get_network_by_path()` and `wp_get_network()` functions.
    
    多站点WordPress安装现在可以使用`get_network_by_path()`和`wp_get_network()`函数。
 *  New action hooks have been added for `wp_install`, `wp_upgrade`, and `wp_playlist_scripts`.
    
    为`wp_install` ， `wp_upgrade`和`wp_playlist_scripts`添加了新的动作挂钩。

## 是时候升级了吗？ **(**Time to Upgrade?**)** ##

Those of a more nervous disposition may prefer to wait a few weeks until issues have been fixed and plugin code is updated. A search for *“WordPress 3.9 upgrade problems”* already returns a long list of pages. That said, I upgraded several standalone and multi-site installations without issues — although few had a significant number of third-party themes and add-ons.

那些比较紧张的人可能希望等待几周，直到问题解决并更新插件代码。 搜索*“ WordPress 3.9升级问题”*已经返回了很长的页面列表。 也就是说，我升级了几个独立的多站点安装，没有问题-尽管很少有大量的第三方主题和附加组件。

My advice: Problems are rare and, if you have a file and database back-up, you have nothing to lose. WordPress 3.9 is excellent — you’ll be glad you upgraded. WordPress 4.0 should be very special…

我的建议：问题很少见，而且如果您有文件和数据库备份，也不会丢失任何东西。 WordPress 3.9非常好-您将很高兴升级。 WordPress 4.0应该非常特别…
