The document discusses Zenoss Core 4, an upcoming release that aims to solve problems with the current Zenoss platform and prepare it for the future. Some of the key changes discussed include using RRDCached to improve data collection, a common collector framework for consistent collection, storing CMDB/Zope data in MySQL instead of flat files, rewriting the event system to use RabbitMQ, and making code available in January with alphas and a final release at the end of February.
