What SSR enhancements does Vue 3.5.25 bring for developers?

Vue 3.5.25 enhances SSR with lazy hydration for async components and tools like useId() and data-allow-mismatch to streamline client-server synchronization.​

Lazy hydration defers component activation until visibility, cutting initial load times and memory use in data-heavy apps.​

The useId() API ensures stable unique identifiers across server and client renders, while data-allow-mismatch suppresses non-critical hydration warnings for cleaner debugging.​These updates boost SSR performance by 56% in memory efficiency, ideal for scalable enterprise deployments
