RubyInstaller-3.0.0-1 has been released! It features a whole bunch of great new features and improvements. See the ruby-3.0.0 release post for more details.

Ruby-3.0.0 finishes the transition to UTF-8 as the primary character encoding on Windows. This enables full Unicode character set for filesystem and environment variables and increases compatibility with other tools and operating systems.

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.

All binaries are available in the Download section!
