This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site to play with the new version.
There are two ways to test the WordPress 5.1 beta: try the WordPress Beta Tester plugin (you’ll want to select the “bleeding edge nightlies” option), or you can download the beta here (zip).
WordPress 5.1 is slated for release on February 21, and we need your help to get there. Here are some of the big items to test so we can find as many bugs as possible in the coming weeks.
Site Health Check
Site Health Check is an ongoing project aimed at improving the stability and performance of the entire WordPress ecosystem. The first phase of this project is included in WordPress 5.1. For the first time, WordPress will catch and pause the problem code, so you can log in to your Dashboard and see what the problem is (#44458). Before, you’d have to FTP in to your files or get in touch with your host.
Additionally, in April 2019, WordPress’ will increase its minimum supported PHP version to 5.6. To help you check if you’re prepared for this change, WordPress 5.1 will show you a warning and help you upgrade your version of PHP, if necessary.
The Cron system can now be more easily replaced with a custom cron handler (#32656).When starting cron under PHP-FPM, the connection will return a response immediately, even for long running cron jobs (dev note).WP_DEBUG_LOG can be set to a custom log location (#18391).Introduced the wp_blogmeta table (#37923).Added LIKE support to meta_key comparisons in WP_Meta_Query (#42409).There have been over 360 tickets closed in WordPress 5.1, with numerous small bug fixes and improvements to help smooth your WordPress experience.
Keep your eyes on the Make WordPress Core blog for more developer notes (which are assigned the dev-notes tag) in the coming weeks detailing other changes in 5.1 that you should be aware of.
