CMS (全称是 C++ Messaging Service) 是一个 C++ 实现的类似 JMS 的 API，用于实现例如 ActiveMQ 的消息代理服务。CMS 可以帮助你的 C++ 客户端代码更见简单。ActiveMQ-CPP 是一个纯客户端库，用它来跟例如 ActiveMQ 等消息服务通讯。
我们的 CMS 实现名为 ActiveMQ-CPP，使用可插入式的传输和协议，当前支持 OpenWire 和 Stomp协议，基于 TCP 和 SSL 。同时支持故障转移传输.
ActiveMQ-CPP 3.8.0 发布了，改进记录包括：
* 3.7.0 does not compile with gcc-4.4.7 on CentOS-6.
* APR-Util header include missed in latest release.
* CMS FailoverTransport leaks Socket Descriptors
* Closing a connection stalled in start because of failover. It should stop the transport safely.
* Compilation error fix for Sun Studio under Solaris 10
* Exception lifetime confusion can cause the application to crash.
* Connection didn't switch to the slave broker when the master broker is down
* Committing a session with a deleted consumer causes access violation.
* Compilation of 3.7.0 fails for Linux systems (Redhat 5.8 and SuSE SLES 10).
* Client doesn't work on Linux Red Hat 6.4 systems, fails when setting thread priority
* Exception "attempt to unlock read lock, not locked by current thread" when doing performance testing
* For SSL connections ensure the SNI field is set.
* Can't send to temporary queues created by name
* Added Visual Studio 2010 project files for the project.
* Added Destination Source events based listener interfaces to the CMS API.
