Trello and LaunchDarkly have integrated their features, allowing teams using Trello for project management to use LaunchDarkly's feature toggles directly within Trello cards. This integration enables teams to attach feature flags to stories or epics, making it easier to track the status of features and deploy them directly from Trello cards. The LaunchDarkly Power-Up respects environment rules and can be installed from the Trello Power-Ups directory.
