LiveScript 1.4.0 发布，此版本包括 source maps；功能性 JSON 命令行处理；改进生成器支持；大量 bug 修复。
更新内容如下：
Changed npm name to livescript as npm no longer allows publishing updates to packages with upper-case letters
Added source map support using the -m,--map flag
Added command line JSON processing with JSON and the -e,--eval flag. Inbound JSON is bound to this
Fixed a regression from previous versions that did not allow for flag style positionals after a first positional (eg. lsc app.ls --flag caused an error)
Generators are no longer auto-hushed, moving behavior in line with what was expected
Allow backcall generators, eg. *<-
Added back -k shorthand for the --const flag
Made it possible to use the by keyword in slices, eg. list[1 til 5 by 2]
Object comprehension bug fixes
Fixed various backcall issues
Fixed composition operator spacing issues
Yield bug fixes - including allowing it to be used with no operand
Replaced deprecated usage of customFds in child_process.spawn
Added CLI tests
Many other bug fixes
LiveScript 是一种脚本语言，最终编译成 JavaScript，LiveScript 在函数式风格编程方面增加了很多新特性，改进了面向对象编程。
