Grails0.6終于發布了，fix了200多個issue，不管從穩定性還是啟動速度方面有了很大的提升。

早在Grails處于開發階段時，我就嘗試了一回，第一次啟動時顯示185ms，但第二次啟動就只有93ms了，因為在第一次啟動時Grails會將腳本緩存起來，并編譯源文件為class文件以免沒有修改過的源文件再次被編譯以節省時間。

此外Grails還集成了Spring Web Flow，支持了SiteMesh的decorator，界面更漂亮 :)
還有很多新特性。。。
具體可以看一下0.6 Release Notes


注意：配置方面的改變請參考朝花夕拾——Groovy & Grails
