Speaking of core updates, something unusual happened last Friday. The auto-update system for WordPress updated some sites from version 5.5.2 to version 5.5.3-alpha due to an error in the Updates API caused by the 5.5.3 release preparations. Fortunately, the 5.5.3-alpha version was “functionally identical” to 5.5.2 since no development work had been started on 5.5.3.
Jake Spurlock goes into more detail about the error. 😯
If your site was auto-updated, the default “Twenty” themes and the Akismet plugin may have been installed. 👀
All current WordPress sites should be updated to the proper 5.5.3 version. ⬆️
