Julia 0.4.0 发布，此版本包括重要的语言优化和大量标准库改进。完整改进列表请看NEWS log。

Julia 0.4.0 现已提供下载。

值得关注的编译器和语言改进

• Incremental code caching for packages
  

• Generational garbage collector
  

• Function call overloading for arbitrary objects

• Generated functions
  

• Support for documenting user functions and other objects

• Improvements in the performance and flexibility of multidimensional abstract arrays,SubArrays (array views), and efficient multidimensional iterators.

• Inter-task channels for faster communication between parallel tasks

• Tuple type improvements: the type tuple (A,B)now written Tuple{A,B}. This change has improved the performance of many tuple-related operations, and allowed one to write fixed-size aggregate fields as field::NTuple{N,T} (Number of elements of given Type).

• Major improvements in Julia’s test coverage and the ability to analyze the test coverage of packages

• The command line (REPL) now supports tab-completion of emoji characters (common LaTeX symbols have been supported since 0.3!)

Julia 0.5 版本开发计划

值得关注的改进：

• A major focus of 0.5 will be further (breaking) improvements to core array functionality, as detailed in this issue.

• We plan to merge the threading branch, but the functionality will be considered experimental and only available as a compile- time flag for the near future.

Julia是一个新的高性能动态高级编程语言。语法和其他编程语言类似，易于其他语言用户学习。Julia拥有丰富的函数库，提供了数字精度、精致的增幅 器（sophisticated amplifier）和分布式并行运行方式。核心函数库等大多数库是由Julia编写，但也用成熟的C和FORTRAN库来处理线性代数、随机数产生和字 符串处理等问题。Julia语言可定义函数并且根据用户自定义的参数类型组合再进行重载。
