The next version is 5.6, which is scheduled to be released on December 8, 2020. The current version is 5.6RC1. A new default theme, Twenty Twenty One, is added to show the functions of the new version. This theme comes with a night mode switch button. It seems that whether the night mode button can be displayed by judging the background color is NB, but it should have nothing to do with the WP version, just the function of the theme.
@I'm song.In the past two days, the domain name has been transferred from www to www. There is no problem with the front-end access of the domain name changing plug-in. It is where the theme options become a long page. There is no way to roll back again.There is more traffic with the www than without it.
