The MongoDB team has released version 2.0 of their Ruby driver, a complete rewrite that improves upon its predecessor, Moped, by incorporating features and design changes learned from years of experience maintaining the current driver and building community drivers like Mongoid and Moped. The new driver is more intuitive and approachable, with a cleaner design and better support for various authentication methods, as well as improved support for MongoDB 3.0 and its features such as CR Auth, GSSAPI Auth, SCRAM-SHA-1 Auth, X509 Auth, and more. The Ruby team has also created a new bson gem version >= 2.0 that is used by the new driver and Mongoid version >= 5.0, which will be released soon as a beta release in RubyGems, with help from users needed to test it out and report any issues.
