It is the second and last major WordPress release of 2017 with some exciting new features and enhancements. In this article, we will show you what’s new in WordPress 4.9 and which features you should try after updating your websites.
Important: Don’t forget to create a complete WordPress backup before starting the update.
New Theme Browsing Experience in The Customizer
WordPress 4.9 brings several improvements to the customizer. These changes offer a better user experience and a new set of tools for developers. Previewing and changing themes directly from customizer is now more user friendly. You can view all your installed themes in the preview panel and click on the live preview button to load them in customizer.
You can also browse and search WordPress.org themes and install them directly from customizer.
Save and Schedule Changes in The Customizer
WordPress 4.9 brings changesets to theme customizer. It is like post revisionsbut for your theme changes. You can store changes without applying them.
This new feature also allows you to easily share a preview of those changes with anyone. Simply copy the preview URL and send it to any user. They will be able to see the new changes without login.
WordPress 4.9 also allows you to easily schedule theme changes to be automatically published later.
Theme developers will now be able to use these new changes in the customizer JS API. These changes will allow them to add better controls, beautiful outer panels, and display notifications on screen.
New Gallery Widget in WordPress 4.9
WordPress 4.8 introduced new media widgets which included rich text, audio, image, and video. WordPress 4.9 builds up on that with the introduction of the new gallery widget.
This new widgets allows you to create a native WordPress gallery and add it to your WordPress sidebar or any widget ready areas.
Add Media Button in Text Widget
The text widget in WordPress 4.8 came with plain text and HTML tabs. However, if you wanted to add an image in sidebar text widget, then you still had to write the HTML code.
WordPress 4.9 has fixed this by adding the ‘Add Media’ button in the text widget. Now you can easily select or upload an image directly inside the text widget.
OEmbed Support Outside Post Content
Previously automatic embeds didn’t work in areas other than post content. With WordPress 4.9, oEmbeds will now work in text widgets and other areas as well.
Shortcode in Sidebar Text Widgets
WordPress didn’t allow shortcode execution in text widgets. Users had to explicitly enable shortcodes in text widgets. WordPress 4.9 will finally change that and users will be able to add shortcodes in text widgets out of the box.
New Code Editing Experience in WordPress 4.9
WordPress allows you to add HTML/CSS code at various places like theme editor, custom CSS panel, or in custom HTML widget.
Previously, these areas were plain text boxes and didn’t look or act like a proper code editor.
WordPress 4.9 has changed that by adding syntax highlighting, code suggestions, and auto-completion into those areas.
If you have ever faced syntax error when editing your theme, then this enhancement will automatically fix many common mistakes that cause such errors.
If you don’t want to use the syntax highlighting feature, then you can still easily disable it. Simply go to your profile page and uncheck the syntax highlighting option.
One of the big usability issues beginners faced was directly making changes from WordPress built-in editor without fully understanding the consequences. A slightest mistake would lead to a syntax error and making their websites inaccessible.
WordPress 4.9 now shows a warning to users when they access the editor.
It will also show users helpful tips and point them to custom CSS panel in the customizer.
However, many users access the editor not to make changes but to quickly look up code. Particularly when they are working on child themes. To help those users, the editor will now recursively show files and folder in the sidebar for easier browsing of all files in a theme folder.
Under The Hood Changes
WordPress 4.9 also brings several great changes for developers as well. Here are some of those under the hood improvements.
Better mapping for theme widgets and navigation menus after switching themes.
Removal of SWFUpload library from the core.
Require a confirmation link in an email to be clicked by admin when a user attempts to change their email address.
We hope this article offered you a good insight into what’s new in WordPress 4.9. We are particularly excited about the customizer changes. What are you excited about?
