The primary new features of Nexus Professional include: * Publishing web sites to Nexus Professional: Nexus Professional 1.4 provides an endpoint for publishing a web site. Users can now configure a site repository that can be used as a publishing destination for project documentation. * Fine-grained control of redeployment for hosted repositories: Nexus 1.4 makes it easier for the administrator to configure a hosted repository to allow for redeployment of previously deployed artifacts, one-time deployment, or to provide a read-only interface for clients. * Improvements to the staging plugin: The staging plugin had numerous improvements in the 1.4 release to provide new functions, such as support for staging rulesets and support for uploading artifact bundles, as well as improvements in the plugin’s user interface, that make the it more intuitive and easier to operate. * User account plugin: This feature in Nexus Professional 1.4 gives unauthenticated Nexus users the ability to sign up for a Nexus account. Nexus administrators can configure the default roles and permissions that are granted to newly signed up users. * Security improvements: With Nexus Professional 1.4 it is now easier than ever to configure and secure a Nexus repository. New user role tree reveals how each role contributes to the permissions for any given user. The new user privilege trace feature allows Nexus administrators to pinpoint which roles contribute which permissions to a particular user, while the new role tree can be used to browse the hierarchy of roles and privileges associated with any Nexus role. Additionally, Nexus now has the capability to configure a role to prevent users from browsing particular repositories. * Integration with Atlassian Crowd: Nexus Professional’s Atlassian Crowd plugin provides seamless integration between Nexus and Atlassian’s Crowd server, a versatile user and directory management system.
