Eksperimentimuutosversioita, often translated as experimental feature flags or feature toggles, is a software development technique used to manage the release of new features. It allows developers to enable or disable specific functionalities within an application without deploying new code. This is achieved by wrapping new features in conditional logic, controlled by a configuration setting, often referred to as a feature flag.

The primary purpose of using experimental feature flags is to reduce the risk associated with deploying new code. By decoupling deployment from release, developers can deploy new features to production in a disabled state. This allows for thorough testing in a live environment without impacting end-users. Once confidence is high, the feature can be enabled for specific users or all users through a simple configuration change.

This technique also facilitates continuous delivery and integration by allowing developers to merge incomplete or experimental features into the main codebase frequently. It supports various release strategies, such as canary releases, where a new feature is rolled out to a small subset of users before a full release, or A/B testing, where different versions of a feature are presented to different user groups to measure their impact.

The management of feature flags can be done through custom-built systems or dedicated feature flag management platforms. These platforms often provide user interfaces for toggling flags, setting targeting rules (e.g., enabling for specific users, percentages of traffic), and monitoring flag performance. Implementing experimental feature flags requires careful planning to avoid technical debt and ensure proper management of the flags throughout their lifecycle.
