Areek (the author of this new version) needed to add a breaking change which is only allowed during major version upgrades, the inter-node communication protocol would have been incompatible making rolling upgrades impossible. Unfortunately there is nothing we can do except following more actively the elasticsearch github repo. In this case it was confusing since the feature was merged but then reverted. David.

Can you translate all of this into user (or product) speak? Where does it leave us as far as any features we have already deployed? Features we have built but not deployed? Features we had hoped to build this quarter?

In this case I assumed that the feature being merged in upstream it would have been available in elastic2.x that we plan to deploy very soon in our cluster. The mistake I made here was to not actively monitor the elasticsearch github repo: the feature has been reverted few months ago, knowing this fact earlier would have certainly helped to review our plans accordingly.

What do you need from the team to make sure we address the issue that areek identifies? --tomasz On Thu, May 5, 2016 at 11:10 AM, David Causse &lt;dcausse(a)wikimedia.org <mailto:dcausse@wikimedia.org>> wrote: Hi, sad news, the completion suggester v2 was reverted from elastic 2.x branch[1] and is now delayed to elasticsearch v5. Unfortunately I was planning to use important features in this version to add realtime support. I'll start to think about it and see if we can workaround and still improve the current implementation. I'm really sorry about that, I should have monitored the elasticsearch repo more closely...
