Meteor 0.6.4 is now available, including a new family of packages to connect to OAuth providers, better support for MongoDB replica sets and primary state changes, and several upstream package updates and bugfixes.

We recommend updating to 0.6.4, which includes upstream security fixes identified by Petr Praus, at your earliest convenience. Those of you on 0.6.0 or later can update individual applications by running meteor update inside each application's directory. If you're new to Meteor, you can get started on OS X or Linux by running

$ curl https://install.meteor.com | /bin/sh

in your terminal window. Windows users can visit win.meteor.com for several unofficial installation options.

Read on for a selected list of changes. Full release notes are available in GitHub.
