WordPress 4.9: New Features & Fatal Error Protection
WordPress 4.9 is the latest major update to the popular content management system, bringing several enhancements and improvements. This version focuses on streamlining site building, boosting developer experience, enhancing security, and overall refinements. For website owners and developers, upgrading to WordPress 4.9 is highly recommended to leverage the new capabilities.
Enhanced Site Building Experience
WordPress 4.9 makes the process of building and managing a site much smoother through UI and UX improvements.
More Reliable Theme Switching
One common frustration site owners faced was losing menu and widget customizations when switching between themes. WordPress 4.9 resolves this issue by ensuring menus, widgets, and other settings persist when a new theme is activated. Now, transitioning between themes is more seamless.
Improved Menu Creation UX
The menu building experience is now more intuitive with better drag and drop capabilities. Rearranging menu items is easier with visible guidelines indicating the placement. Overall, the entire menu creation process is now more beginner-friendly.
Developer-Focused Enhancements
For developers and advanced users, WordPress 4.9 brings helpful improvements like refined APIs and inclusion of useful tools.
Customizer JS API Improvements
The Customizer JS API has been improved for a faster development experience. Changes in preview areas now reflect quicker without delay. There is better support for dynamic content rendering as well. These benefits make building custom WordPress sites more efficient.
CodeMirror Integration
The CodeMirror library is now integrated into WordPress Core for code editing purposes. It replaces the previous Ace Editor with improved usability. CodeMirror also enhances accessibility for those relying on screen readers or keyboard navigation.
Fatal Error Protection
One major security enhancement in WordPress 4.9 is the introduction of fatal error protection. This shields your site from crashes due to plugins or themes causing fatal errors.
How Fatal Error Protection Works
Essentially, WordPress 4.9 isolates faulty code execution to prevent crashes. When a fatal error occurs due to a plugin or theme, WordPress logs the error and skips the broken code. This allows the rest of the site to remain functional instead of a white screen of death. This added layer of protection safeguards your site’s stability.
Additional Features and Improvements
Beyond the highlighted changes above, WordPress 4.9 contains other useful additions like:
- Autosave revisions for Customizer settings to easily revert unwanted changes.
- Improved widget editing interface for managing sidebars and placements.
- Better support for responsive embedded videos.
Updating to WordPress 4.9
Updating to the latest version is a best practice for performance and security. For WordPress 4.9, here are tips for a smooth update:
- Back up your site fully before updating.
- Use a staging or development environment to test the update first.
- Update plugins and themes for compatibility.
- Follow the one-click update in wp-admin or use auto-updates.
- Monitor your site for any issues after updating.
- Revert to a previous version if major problems occur.
Conclusion
WordPress 4.9 is a worthwhile update for all users with improvements ranging from site building to fatal error protection.
