Immutant 2 的第二个 Alpha 版本发布了，Immutant 是一个 Clojure 的应用服务器，这是一个基于 JBoss AS 7 的集成平台，用于 Ring 处理、异步消息、缓存、任务调度、XA 事务、集群和守护进程等等。
与 1.x 版本比较，版本 2 主要值得关注的有：
•使用 Undertow web 服务器，更快而且支持 WebSocket
•使用 Apache 许可证，而不是之前的 LGPL
•完全的可嵌入到应用中，无需应用服务器支持
•可部署到最新的 WildFly 获得额外特性
而 Alpha2 版本的主要改进有：
•对文档进行重新安排
•引入 org.immutant/transactions 库以提供 XA 分布式事务支持
•更灵活的 SSL 配置
•对消息 API 进行大量改进以及接口大幅调整
• Datomic 可与一个 Immutant 应用一起使用，无需修改 WildFly 配置
•HornetQ 可通过标准的配置文件或者 java 代码进行配置
同时我们发布了新版本的 lein-immutant plugin (2.0.0-alpha2). 如果你使用 Immutant Alpha2 和 WildFly 需要升级这个版本。
这里有一些演示程序： Feature Demo
