Deployment patterns
Classical deployment pattern
In a classical development and deployment environment, (monolithic) software moves in stages between environments culminating in a release like a dump truck delivering a load of dirt. If you're delivering software this way, it's a complete misnomer to call this a feature release. Instead, it is a new "version", with a whole bunch of new features, bug-fixes and changes bundled together.

Modern deployment patterns
In a Continuous Delivery environment, where testing is encouraged in Production, changes are not delivered in a "big bang" or by the truck-load. It's possible to deploy features without exposing them to all users and to deploy them as discreet enhancements.
Modern deployment patterns in a Continuous Delivery environment include:
- Blue-green deployments
- Canary releases
- Dark launching
- A/B testing
- Progressive exposure or ring-based deployment
- Feature toggles
