Migration Guide

Preparing for WordPress 3.8

For Theme Developers

1. Test with the new admin design: Ensure your theme's admin customizations work with the new responsive design.
2. Update icon references: If your theme or plugin uses core admin icons, update to use the new Dashicons or SVG icons.
3. Review dashboard widgets: If you've created custom dashboard widgets, test them with the new dashboard layout.
4. Check RTL compatibility: If your theme supports RTL languages, test with the new RTL improvements.

For Plugin Developers

1. Dashboard hooks: Update any code using the deprecated right_now_* hooks to use the new dashboard_glance_items filter.
2. Menu icons: Consider updating your plugin's menu icons to use the new Dashicons system:

   // Old way
   add_menu_page('My Plugin', 'My Plugin', 'manage_options', 'my-plugin', 'my_plugin_page', plugins_url('images/icon.png', __FILE__));
   
   // New way with Dashicons
   add_menu_page('My Plugin', 'My Plugin', 'manage_options', 'my-plugin', 'my_plugin_page', 'dashicons-admin-generic');
   

3. Test responsive behavior: Ensure your plugin's admin pages work well at all screen sizes.
4. Image references: Check if your plugin references any of the removed admin images and update accordingly.

For Site Administrators

1. MP6 Plugin: If you were using the MP6 plugin for the new admin design, it will be automatically deactivated upon updating to 3.8.
2. Widget placement: Be aware that the widget management system now adds widgets to the bottom of sidebars by default instead of the top.
3. Mobile testing: Test your admin workflows on mobile devices to ensure a smooth transition.

Upgrade Recommendations

Recommendation: Standard upgrade recommended for all users.

WordPress 3.8 is a significant update that brings major improvements to the admin interface and user experience. The update is focused on visual and usability enhancements rather than major functional changes, making it a relatively safe upgrade for most sites.

Before Upgrading:

1. Create a complete backup of your WordPress site (files and database)
2. Test on a staging environment if possible, especially if you have custom themes or plugins that modify the admin interface
3. Update all plugins and themes to their latest versions
4. Check plugin compatibility with WordPress 3.8

Special Considerations:

• If you were using the MP6 plugin for the new admin design, it will be automatically deactivated upon updating to 3.8
• Theme and plugin developers who have created custom admin interfaces should test thoroughly with the new responsive design
• Sites with extensive admin customizations may need to update their CSS to work with the new design

The visual nature of this update means users will immediately notice changes, but the core functionality remains consistent with previous versions. The responsive improvements make this update particularly valuable for users who manage their sites from mobile devices.

Color Schemes

WordPress 3.8 introduces eight color schemes to personalize your admin experience. Choose from Default, Light, Blue, Coffee, Ectoplasm, Midnight, Ocean, and Sunrise to make WordPress your own.

Dashicons

The new vector-based icon font called Dashicons ensures that WordPress icons look crisp and beautiful at any screen size. These icons replace the old image-based icons, improving performance and visual quality.

Widget Management

Widget management has been simplified with a new interface that allows you to click and add widgets directly to your sidebars without dragging and dropping.

Security Updates

No significant security fixes were specifically mentioned in the release notes for WordPress 3.8. The release appears to focus primarily on user interface improvements, new features, and bug fixes rather than security enhancements.

SVG Painter Optimization

The SVG painter has been optimized to:

• Delay executing IE9-specific base64 code when not needed
• Improve icon color transition performance
