Looks like a great release! Can't wait to get this installed and going on our system. We use getAll almost everywhere, so that's going to be a very, very welcome improvement.

Awesome to see Rethink continue to mature quickly and nicely.

From the FAQ:

We recommend RethinkDB servers have at least 2GB of RAM

Why does it needs so much memory?

This is a really exciting release! Atomic changefeeds make it much more consistent and robust to subscribe to realtime data in the client, and the performance improvements look incredible.

There's a fairly major breaking change for a minor version bump.

Because it's 2015.

Because it's 2015.

And it’s a database with indexes and caches.

I don't think there are actually any breaking changes. The release notes say "includeInitial" is breaking, but I think all of your existing application code will continue to run the same if you upgrade RethinkDB. It's just that new code using includeInitial will fail on old versions of RethinkDB.
