在 Ceylon 1.2.0 发布 4 个月,1.2.1 发布一个月后,Ceylon 发布了 1.2.2 维护版本,该版本关闭超过 70 issues ,其中包括新特性、提升和 bug 修复,诸如:

you can now use java.lang.Iterable and arrays in for statements and comprehensions,
the [] lookup operator works on Java lists, arrays and maps,
the in operator works on java.util.Collection and last but not least
a new ceylon bootstrap command to make it really easy to distribute code to people that don't have Ceylon installed.

该版本包含:

a complete language specification that defines the syntax and semantics of Ceylon in language accessible to the professional developer,
a 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,
a powerful module architecture for code organization, dependency management, and module isolation at runtime,
the language module, our minimal, cross-platform foundation of the Ceylon SDK, and
a full-featured Eclipse-based integrated development environment.

Ceylon面向企业级应用开发设计,在JVM运行时基础上执行,支持与Java的交互操作。Ceylon语言充分借鉴了Java语言的优势并屏蔽其在设计上的不足,使用静态类型并提供高阶函数支持,在保持代码良好可读性的同时进一步降低开发者入门的难度。

Ceylon语言没有设计特殊的Primitive类型或复合类型,所有类型在类型系统内部都是可表达的。Ceylon的通用类型设计比Java的 实现更为简便,而且相比其他类Java语言具备更高的安全性,Ceylon的元编程(Reflection)也必须是类型安全的。此外,Ceylon语言 减少了开发者对于配置文件的依赖,屏蔽了Java开发者常常需要对各种XML进行的配置和修改操作。
