JFrog's Release Lifecycle Management (RLM) offers a streamlined and robust alternative to the legacy build promotion API by providing a more comprehensive approach to managing release candidates throughout their lifecycle. RLM ensures the immutability of releases from build to production, maintaining integrity and traceability while enabling faster, more reliable releases with full control and visibility. Central to RLM is the concept of Release Bundles, which encapsulate release candidate versions and support actions such as creation, promotion, and distribution, along with the inclusion of Evidence, which captures all testing, scanning, and approval metadata for auditability. This system enhances the traditional build promotion process by eliminating manual errors, providing a unified promotion step for multi-technology pipelines, and offering detailed visibility through features like the RLM Kanban Board. JFrog facilitates the transition for users of the legacy system by automating certain processes and aligning environmental configurations, ensuring a smooth shift to the enhanced capabilities of RLM.
