* Added 3.1.0-preview1

ruby-build 20211019

* Prefer maven URLs going forward

  We continue to maintain the S3 URLs but only as a courtesy for
  legacy apps and tools. The preferred URLs are the maven jruby-dist
  links, which have the same files but are federated and mirrored
  across the maven ecosystem.

* Add JRuby 9.3.1.0

* Add TruffleRuby and TruffleRuby GraalVM 21.3.0

ruby-build 20210928

* Fix version check for Java 17

  * Fixes https://github.com/rbenv/ruby-build/issues/1798
  * OpenJDK 17 reports:
    $ java -version
    openjdk version "17" 2021-09-14
    There is no dot in the version, so we need to only use the first match from grep -o.
  * Clarify it is a minimum required java version, not an exact version.

ruby-build 20210925

ruby-build 20210726

* Ensure it is safe to remove the prefix path for TruffleRuby or error

  * Only do clean_prefix_path for TruffleRuby and rename for clarity,
    since the logic is now TruffleRuby-specific.

ruby-build 20210707

ruby-build 20210526

* Fix hashes for TruffleRuby 21.1.0

  * Unfortunately the original builds were based on incorrect JDK versions,
    these new hashes represent the correct builds based on JDK11.

ruby-build 20210510

* Join *_OPTS variables after *_OPTS_ARRAY variables

  This for instance allows `RUBY_CONFIGURE_OPTS` to override
  what's set by the definition.

  For instance `enable_shared` can be disabled with `RUBY_CONFIGURE_OPTS='--disable-shared'`

* Do not append `--enable-shared` if RUBY_CONFIGURE_OPTS include `--disable-shared`

ruby-build 20210423

* Fix hashes for TruffleRuby GraalVM 21.1.0
