Modern teams use feature flags

Feature flags are a technique that allows you to turn on or off features without having to deploy new code. Code for a new feature can live in a production environment for any duration of time without disruption to your customer. When the feature is ready, any team member can turn it on. If there is an issue for any reason, the feature can be easily shut off, limiting impact.

With Molasses, feature releases can be a part of your go-to-market timeline and allows your team to worry less about merge conflicts and long lived feature branches.
