Strongly +1 for adding system test for different interpreter modes and focus on bug fixing than new features. I do heard from some users complain about the bugs of zeppelin major release. A stabilized release is very necessary for community.

List of features for 0.8.0 looks really good. Interpreter factory refactoring Interpreter layer supports various behavior depends on combination of PerNote,PerUser / Shared,Scoped,Isolated. We'll need strong test cases for each combination as a first step. Otherwise, any pullrequest will silently break one of behavior at any time no matter we refactor or not. And fixing and testing this behavior is so hard. Once we have complete test cases, not only guarantee the behavior but also make refactoring much easier. 0.8.0 release I'd like to suggest improvements on how we release a new version. In the past, 0.6.0 and 0.7.0 release with some critical problems. (took 3 months to stabilize 0.6 and we're working on stabilizing 0.7.0 for 2 months) I think the same thing will happen again with 0.8.0, while we're going to make lots of changes and add many new features. After we released 0.8.0, while 'Stabilizing' the new release, user who tried the new release may get wrong impression of the quality. Which is very bad and we already repeated the mistake in 0.6.0 and 0.7.0. So from 0.8.0 release, I'd suggest we improve way we release new version to give user proper expectation. I think there're several ways of doing it. 1. Release 0.8.0-preview officially and then release 0.8.0. 2. Release 0.8.0 with 'beta' or 'unstable' label. And keep 0.7.x as a 'stable' release in the download page. Once 0.8.x release becomes stable enough make 0.8.x release as a 'stable' and move 0.7.x to 'old' releases. After 0.8.0, Since Zeppelin projects starts, project went through some major milestone, like - project gets first users and first contributor - project went into Apache Incubator - project became TLP. And I think it's time to think about hitting another major milestone. Considering features we already have, features we're planning on 0.8, wide adoption of Zeppelin in the industry, I think it's time to focus on make project more mature and make a 1.0 release. Which i think big milestone for the project. After 0.8.0 release, I suggest we more focus on bug fixes, stability improvement, optimizing user experience than adding new features. And with subsequent minor release, 0.8.1, 0.8.2 ... moment we feel confident about the quality, release it as a 1.0.0 instead of 0.8.x. Once we have 1.0.0 released, then I think we can make larger, experimental changes on 2.0.0 branch aggressively, while we keep maintaining 1.0.x branch.

I think it's very positive signals to improve Apache Zeppelin and its community. But in another aspect, we should focus on what the next release includes. I think we need to summarize and prioritize them. Here is what I know: * Cluster management * Admin feature * Replace some context to separate users * Helium online Feel free to talk if you want to add more things. I think we need to choose which features will be included in 0.8.0, too. Regards, Jongyoul Lee -- 이종열, Jongyoul Lee, 李宗烈 http://madeng.net
