Release Notes: Users can now share issues and search results with each other. They can also mention a colleague with "@username" in an issue to call attention to it. Remote issue links connect JIRA issues to objects and pages in other Web applications. Activity streams show events from all linked Atlassian applications and third-party apps. New APIs are designed for developers who want to connect JIRA to other applications: new REST APIs to manage every facet of an issue, new APIs for remote issue links and activity streams, and a stable Java API for JIRA.
