Hi Folks,

WSO2 Carbon team is pleased announce the release of the Carbon Kernel 4.3.0.

*What is WSO2 Carbon*

WSO2 Carbon redefines middleware by providing an integrated and
componentized middleware platform that adapts to the specific needs of any
enterprise IT project - on premise or in the cloud. 100% open source and
standards-based, WSO2 Carbon enables developers to rapidly orchestrate
business processes, compose applications and develop services using WSO2
Developer Studio and a broad range of business and technical services that
integrate with legacy, packaged and SaaS applications.

WSO2 Carbon kernel, the lean, modular, OSGi-based platform, is the base of
the WSO2 Carbon platform. It is a composable server architecture which
inherits modularity and dynamism from OSGi framework. WSO2 Carbon kernel
can be considered as a framework for server development. All the WSO2
products are composed as a collection reusable components running on this
kernel. These products/components inherits all the core services provided
by Carbon kernel such as Registry/repository, User management, Transports,
Caching, Clustering, Logging, Deployment related features.
