Building on the agile permission framework that was adopted at the end of last year, ggKbase 5.3 brings more granular control over memberships and permissions to the owner of the resources on ggKbase. For this rollout, project owners now can not only add members to their projects, but also provide their members fine-grained control over what actions each member ca perform, such as binning the project, or editing the project details. Soon we will be rolling out this capability to other resources, e.g. lists and genome summaries. This is a necessary step forward in making ggKbase a more secure and collaborative platform.
