ウィジェットのエキサイティングな更新

Exciting Widget Updates

Image Widget
Adding an image to a widget is now a simple task that is achievable for any WordPress user without needing to know code. Simply insert your image right within the widget settings. Try adding something like a headshot or a photo of your latest weekend adventure — and see it appear automatically.
Video Widget
A welcome video is a great way to humanize the branding of your website. You can now add any video from the Media Library to a sidebar on your site with the new Video widget. Use this to showcase a welcome video to introduce visitors to your site or promote your latest and greatest content.
Audio Widget
Are you a podcaster, musician, or avid blogger? Adding a widget with your audio file has never been easier. Upload your audio file to the Media Library, go to the widget settings, select your file, and you’re ready for listeners. This would be a easy way to add a more personal welcome message, too!
Rich Text Widget
This feature deserves a parade down the center of town! Rich-text editing capabilities are now native for Text widgets. Add a widget anywhere and format away. Create lists, add emphasis, and quickly and easily insert links. Have fun with your newfound formatting powers, and watch what you can accomplish in a short amount of time.

リンク境界

Link Boundaries

Have you ever tried updating a link, or the text around a link, and found you can’t seem to edit it correctly? When you edit the text after the link, your new text also ends up linked. Or you edit the text in the link, but your text ends up outside of it. This can be frustrating! With link boundaries, a great new feature, the process is streamlined and your links will work well. You’ll be happier. We promise.

近隣の WordPress イベント

Events Widget

Did you know that WordPress has a thriving offline community with groups meeting regularly in more than 400 cities around the world? WordPress now draws your attention to the events that help you continue improving your WordPress skills, meet friends, and, of course, publish!

This is quickly becoming one of our favorite features. While you are in the dashboard (because you’re running updates and writing posts, right?) all upcoming WordCamps and official WordPress Meetups — local to you — will be displayed.

Being part of the community can help you improve your WordPress skills and network with people you wouldn’t otherwise meet. Now you can easily find your local events just by logging in to your dashboard and looking at the new Events and News dashboard widget.

詳細

開発者向け

管理パネル見出しのアクセシビリティを向上

New CSS rules mean extraneous content (like “Add New” links) no longer need to be included in admin-area headings. These panel headings improve the experience for people using assistive technologies.

WMV、WMA ファイルのコアサポート終了

As fewer and fewer browsers support Silverlight, file formats which require the presence of the Silverlight plugin are being removed from core support. Files will still display as a download link, but will no longer be embedded automatically.

マルチサイトに関する更新

New capabilities have been introduced to 4.8 with an eye towards removing calls to is_super_admin(). Additionally, new hooks and tweaks to more granularly control site and user counts per network have been added.

テキストエディター JavaScript API

With the addition of TinyMCE to the text widget in 4.8 comes a new JavaScript API for instantiating the editor after page load. This can be used to add an editor instance to any text area, and customize it with buttons and functions. Great for plugin authors!

メディアウィジェット API

The introduction of a new base media widget REST API schema to 4.8 opens up possibilities for even more media widgets (like galleries or playlists) in the future. The three new media widgets are powered by a shared base class that covers most of the interactions with the media modal. That class also makes it easier to create new media widgets and paves the way for more to come.

カスタマイザー幅の変数

Rejoice! New responsive breakpoints have been added to the customizer sidebar to make it wider on high-resolution screens. Customizer controls should use percentage-based widths instead of pixels.
