Status and Roadmap

The project currently support the core specifications.

We released version 1.3 in early 2026. We have recently merged LionWeb-Java and LionWeb-Kotlin in LionWeb-JVM.

The library is mature with great support for serialization, language definition, nodes manipulation, code generation, and the LionWeb Archive format.

We are progressing on:

• Completing support for the Delta protocol
• Solve any issue reported
• Constantly optimize performance

The project is used in production and actively maintained.
