Drools开发小组宣布发布Drools 2.5.
Drools 是一个基于Charles Forgy's的Rete算法的，专为Java语言所设计的规则引擎。Rete算法应用于面向对象的接口将使基于商业对象的商业规则的表达更为自然。Drools是用Java写的，但能同时运行在Java和.Net上。
官方提到:
"The drools team is happy to announce the release of Drools 2.5. This is essentially a maintenance release, and will be the last version of drools 2.x lineage before the all singing, all dancing Drools 3 is out (which is quite a different codebase, watch this space)."
2.5将是3.0之前的最后一个版本。
