RubyInstaller versions 3.0.2-1, 2.7.4-1 and 2.6.8-1 are released. These are maintenance releases with bug and security fixes.
Please note, that some gems are not yet compatible with Ruby-3.0 on Windows. In this case you might stay on 2.7 until 3.0 is well supported.
A previous RubyInstaller-2.6.x or 2.7.x installation should not be updated by installing RubyInstaller-3.0.x into the same directory. This is because gems with C extensions are not compatible between ruby-2.7 and 3.0. It’s best to use a new directory for 3.0.x as proposed by the installer.
