After four months of development led by Konstantin Obenland, WordPress 4.3 “Billie” named after jazz singer Billie Holiday, is available for download. This release features menus in the customizer, strong passwords by default, site icons, and variety of other improvements. Menus in the Customizer You can now create, add, and edit menus in the customizer while previewing changes to your site in real-time. Unlike other parts of the customizer, previewing menus should be fast as it uses a new hybrid transport layer. Weston Ruter, who contributed to fast previews in the customizer explains the approach. We also wanted to enable fast previewing of menu changes by default. So we implemented a postMessage/refresh hybrid approach which uses postMessage to sync the menus settings to the preview, and then the preview does an Ajax request to render just the contents of the menu container, and this Ajax response is then inserted into the DOM to replace the previous menu container. The technical name for this approach we have been calling ‘partial refresh’, but you can call it fast preview. In general, previewing menus in most themes should be a fast experience.
