Feature flag
Also called: Feature toggle, Remote config
A switch that turns a feature on or off without releasing a new build.
Definition
Teams release code hidden behind flags and turn it on for testers, a small percentage of users, or everyone. Testers need to know which flags are on when they test.
In practice
The new checkout is only visible when the 'checkout_v2' flag is enabled for your test account.
