If there are no further issues with my implementation, would you please rollout a new Beta version soon. I'm currently hacking in my branch into another project manually, but it would be much more convenient to upgrade dependencies to the new version.

Yes, a new release is coming soon. Specifically, I'm planning to do one in the week from March 14h. Would that work for you?

The implementation could take advantage of upgrading the MongoDB Java driver to the latest release 3.2.x. This would make it possible to better support findAndModify and remove queries.

Sounds good. Could you open a JIRA issue for this one and if you like also send in a patch?
