WordPress 5.0 introduces the new block-based post editor. This is the first step toward an exciting new future with a streamlined editing experience across your site. You’ll have more flexibility with how content is displayed, whether you are building your first site, revamping your blog, or write code for a living.
The block editor is used on over a million sites, we think it’s ready to be used on all WordPress sites. We do understand that some sites might need some extra time, though. If that’s you, please install the Classic Editor plugin, you’ll continue to use the classic post editor when you upgrade to WordPress 5.0.
Twenty Nineteen is WordPress’ new default theme, it features custom styles for the blocks available by default in 5.0. Twenty Nineteen is designed to work for a wide variety of use cases. Whether you’re running a photo blog, launching a new business, or supporting a non-profit, Twenty Nineteen is flexible enough to fit your needs.
The block editor is a big change, but that’s not all. We’ve made some smaller changes as well, including:
- All of the previous default themes, from Twenty Ten through to Twenty Seventeen, have been updated to support the block editor.
- You can improve the accessibility of the content you write, now that simple ARIA labels can be saved in posts and pages.
- WordPress 5.0 officially supports the upcoming PHP 7.3 release: if you’re using an older version, we encourage you to upgrade PHP on your site.
You can read more about the fixes and changes since Beta 5 in the last update post.
