Immutant 2 Beta3 发布，此版本主要有以下更新： The concurrency for queue listeners now defaults to the number of cores to provide better messaging throughput out of the box (it was 1). The default for topic listeners remains at 1. The :subscription-name option to immutant.messaging/context has been renamed to :client-id to remove confusion with the :subscription-name option to immutant.messaging/subscribe. Both are only used for durable topic subscribers. immutant.messaging.pipeline/pipeline error handlers now get passed the decoded message instead of the Messageobject, and there is now a immutant.messaging.pipeline/retry function to ease retrying messages from the error handler. You can now set the headers and status of an async HTTP channel response when calling immutant.web.async/send!. You can also now provide any valid Ring body type in addition to String and byte[] to send!. The n-complete option to immutant.web.async/send! has been replaced with two separate callback options:n-success and n-error. immutant.transactions/manager is now a function instead of a value. If you were using the manager directly, you'll now need to invoke it. 详细信息请查看发行页面。 此版本现已提供下载： https://github.com/immutant/immutant/archive/2.0.0-beta3.zip 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。 Immutant 2 Beta3 发布，Clojure 应用服务器下载地址
