2.12.1

This feature release of the Ruby driver for MongoDB adds two major features:

• Client-side encryption
• Extended JSON parsing

The following notable changes and bug fixes have been made since 2.12.0.rc0:

• RUBY-2219 Force read preference primaryPreferred in Single topology
• RUBY-2176 Provide a descriptive error message in CSE when AWS key or secret are empty strings
