Rhino 1.8.0

Highlights

Rhino 1.8.0 contains some significant changes, so we're incrementing the final version number for the first time in a very long time. Here are a few highlights:

• Rhino now requires Java 11 minimum. We currently test against Java 11, 17, and 21.
• Rhino has been broken down into individual Java modules that are properly encapsulated as Java Modules. See README.md for a breakdown of which modules are which -- short answer is that everyone will need the "rhino" module and many will need others.
• Older code not able to adapt to using multiple JARS can still use the "rhino-all" module, which publishes an "all-in-one" JAR like the old "rhino.jar".
• The default language level is "VERSION_ES6". That means that modern JavaScript features supported by Rhino will work by default.
• There are big improvements in compatibility, including support for "super", reflect and proxy, and lots of other language features. See the compatibility table for the details.

JARs have been published to Maven Central and GitHub packages.

Thanks to all who contributed -- we had 24 contributors to this release, with some new contributors who added significant capabilities. Please keep the contributions and attention coming!
