TruffleRuby 25.0.0

TruffleRuby is a high-performance implementation of the Ruby programming language. It aims to be fully compatible with the standard implementation of Ruby, MRI.

More information is available at https://github.com/oracle/truffleruby/blob/master/README.md.

TruffleRuby comes in two standalone modes, native and jvm, each built with both Oracle GraalVM and Community Edition. See the documentation for which release asset corresponds to what.
