Unleash brings powerful Constraints feature to OSS users

Unleash has introduced the Strategy Constraints feature to its open-source users with the release of version 4.16, a previously Enterprise-only feature that allows for granular control over feature visibility by adding preconditions to activation strategies. This enhancement supports 15 different constraint operators, enabling users to target specific user segments based on attributes like region or email domain, and facilitates scheduling feature releases and other tailored rollout strategies. The strategy constraints can replace custom activation strategies, simplifying the implementation process across SDKs. To utilize this feature, users must upgrade to version 4.16 and configure strategy constraints through the Unleash platform, using context fields to define the conditions that must be met for a strategy to pass. The new feature is accessible via Docker hub for those with versions 4.0 and above, while earlier version users should follow a migration guide for updates. A demo instance is available for users interested in exploring the capabilities of strategy constraints.
