Is Node Mongodb Native Driver v 2.2 still compatible with node 0.12.X?

Question

I use the Mongodb Native Driver For Node v2.1 with a node app in 0.12.X version. I've just upgrade the driver to the 2.2 version, but I get this error with a simple insert:

/web-apps/j2ee/jenkins/back/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:320
  self.s.pool = new Pool(Object.assign(self.s.options, options, {bson: this.s.

The documentation for driver compatibility is not to date, as there is only the requirements for the 2.1 version. They seems to use ES2015 features (Object.assign) that is not compatible with node 0.12.X.

Do I have to stay in v 2.1?

I've just found an issue on their Jira tracker, this bug will be fixed in the next release, the 2.2.1.
