Release notes

Sourced from org.mozilla:rhino's releases.

Rhino 1.9.0

This release represents about a year of work on Rhino by a growing team of contributors.

Some of the improvements include:

• Compatibility improvements in areas like destructuring and spread syntax.
• Performance improvements from 10 to 30% in benchmarks like Delta Blue, Earley-Boyer, and Crypto in both interpreted and compiled mode
• Better support for generics and other things when Java integration is used.

Some other improvements:

JavaScript Language Updates:

• ES6+: Significant advancements in destructuring, spread syntax for arrays/objects, Symbol API, and improved let/const scoping. TypedArray.from/of and BigInt.asUintN/asIntN fixes.
• RegExp: New features like named capture groups, lookbehind assertions, and Unicode mode support.
• Future ES (ES2024/2025): Early implementation of proposals such as Promise.withResolvers, Promise.try, ArrayBuffer transfer methods, and new Set methods.

Core Engine Enhancements:

• Major Refactoring: Extensive migration of built-in objects to a lambda-based architecture and a comprehensive overhaul of the interpreter bytecodes for better performance and maintainability.
• Concurrency & Interop: Continued focus on thread safety improvements and enhanced Java interoperability, including better generics support.

Going forward -- we have lots of plans for Rhino, including some changes that may affect compatibility for projects that embed Rhino into larger frameworks. We think that these changes will be worth it because they will unlock better language compatibility and performance.

As such, the next version going forward will be 2.0.0-SNAPSHOT.

16 different contributors gave their time and energy to Rhino 1.9.0.

Thanks to everyone who contributed!
