This would eliminate the need for a bridge (https://github.com/ReactiveX/RxJavaReactiveStreams). \r\n\r\nRxJava 2.0 must be namespaced separately from 1.0 since RxJava 1.0 is committed to never breaking. This is essential in order for RxJava to be usable similar to `java.util` collections. \r\n\r\nThe proposed namespacing is:\r\n\r\n```\r\nJava Package: io.reactivex.* (changed from rx.*)\r\nMaven GroupID: io.reactivex (no change)\r\nMaven ArtifactId: rxjava2 (changed from rxjava)\r\n```\r\n\r\nIssues for 2.0: https://github.com/ReactiveX/RxJava/milestones/2.0"},"comment":{"url":"https://api.github.com/repos/ReactiveX/RxJava/issues/comments/76536148","html_url":"https://github.com/ReactiveX/RxJava/issues/2450#issuecomment-76536148","issue_url":"https://api.github.com/repos/ReactiveX/RxJava/issues/2450","id":76536148,"user":{"login":"benjchristensen","id":813492,"avatar_url":"https://avatars.githubusercontent.com/u/813492?v=3","gravatar_id":"","url":"https://api.github.com/users/benjchristensen","html_url":"https://github.com/benjchristensen","followers_url":"https://api.github.com/users/benjchristensen/followers","following_url":"https://api.github.com/users/benjchristensen/following{/other_user}","gists_url":"https://api.github.com/users/benjchristensen/gists{/gist_id}","starred_url":"https://api.github.com/users/benjchristensen/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/benjchristensen/subscriptions","organizations_url":"https://api.github.com/users/benjchristensen/orgs","repos_url":"https://api.github.com/users/benjchristensen/repos","events_url":"https://api.github.com/users/benjchristensen/events{/privacy}","received_events_url":"https://api.github.com/users/benjchristensen/received_events","type":"User","site_admin":false},"created_at":"2015-02-28T17:34:50Z","updated_at":"2015-02-28T17:34:50Z","body":"The list of issues for 2.0 are marked with the 2.0 milestone: https://github.com/ReactiveX/RxJava/milestones/2.0\r\n\r\nSome important ones as we design include:\r\n\r\n- #2781 2.0 Design: ReactiveX Design Guidelines and Contract\r\n- #2780 2.0 Design: Resource Cleanup\r\n- #2782 2.0 Design: Disposal and Cancellation\r\n- #2785 2.0 Design: Hot and Cold\r\n- #2783 2.0 Design: Test Suite\r\n- #2784 2.0 Design: Performance Benchmarking"}}
