* In TruffleRuby 23.1+, the GraalVM Updater (`gu`) is no longer available in GraalVM,
instead JVM Standalones and Maven artifacts are provided to replace `gu`.
* See https://github.com/oracle/graal/issues/6855
truffleruby+graalvm-dev currently delivers builds using both the latest Java and the latest Java LTS release as a base. Since the latest Java changes more frequently than the LTS release, using the LTS as a base helps prevent the URLs from growing stale.
