Architectural Issues

This release of Kura introduces some breaking changes within the APIs in order to introduce new features that will make development and integration easier (Cloud Connection APIs), but also cleaning out old and deprecated APIs.

The project has also started a review of the supported platforms, in order to be able to concentrate the support to a more defined set of targets.

 

Security Issues
