Released today, @mastra/[redacted] adds declarative step entry types with toStorableGraph() and rehydrateWorkflow(), so UI- or LLM-authored workflow graphs survive restarts with schema-typed chaining. Stored workflows are manageable over HTTP, persist through a new workflowDefinitions storage domain across major DB adapters, and a structural predicate DSL replaces closure-only predicates so branches and loops actually serialize. Breaking: @mastra/[redacted] drops MASTRA_PLATFORM_SECRET_KEY auth. LLM-authored workflows need a serializable representation, and closures were always the blocker.
