如何使用DoctrineCouchDBBundle和SF 2.8插入模型?

I've a fresh install of Symfony 2.8 and DoctrineCouchDBBundle. I've created a minimal model to try to insert an object into CouchDB, but I have the following error :

HTTP Error with status 417 occurred while requesting /symfony/_bulk_docs. Error: not_implemented all_or_nothing is not supported 

I read in this post that all_or_nothing could be removed in CouchDB 2.0, is it done ? I am using CouchDB 2.0 and I would use Doctrine with Couchdb 2.0. Is it a Doctrine problem, or a DoctrineCouchDBBundle problem that is not up to date with the last Doctrine version ?

I got this working by turning off all_or_nothing while using CouchDB 2.0

My config.yml looks like this now:

doctrine_couch_db:
  client:
    dbname: symfony
  odm:
     document_managers:
      default:
        all_or_nothing_flush: false
        auto_mapping: true
