Ceylon, the modular, statically typed programming language for the Java and JavaScript virtual machines, just released version 1.2.2 with over 70 fixes and additional features.
Some of the changes in the new release include:
- Complete language specification that defines the syntax and semantics of Ceylon in language accessible to the professional developer,
- Command line toolset including compilers for Java and JavaScript, a documentation compiler, a test runner, a WAR archive packager, and support for executing modular programs on the JVM and Node.js,
- Powerful module architecture for code organization, dependency management, and module isolation at runtime.
- Language module, a minimal, cross-platform foundation of the Ceylon SDK, an
- Full-featured Eclipse-based integrated development environment.
Sadly, on the JavaScript backend, Ceylon had to break binary compatibility to fix serious interoperation issues, and so modules compiled for 1.2.2 and 1.2.0 are not compatible. Versions 1.2.1 and 1.2.2 are binary compatible but can still give problems when used together. They recommend you upgrade your distribution to 1.2.2 and recompile your modules.
