PureScript 0.6.8 发布，此版本更新内容如下：
重大改进
The Num type class has been refined to allow more interesting instances. The Semiring, ModuloSemiring, Ring and DivisionRing classes have been introduced. Most code should continue to compile, since Number was one of only a handful of instances, but library developers will need to break up their Num instances.
功能增强
@garyb has improved the readability of psc-docs output.
注意
全面废弃了 ErrorT ，使用 ExceptT 和 transformers 替换， mtl 依赖有点小改动
PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。purescript 主要是由 Haskell 和 PureScript 编写的。
