2025-06 monthly summary for Apicurio/apicurio-registry focused on performance optimization in the ScriptingService. Implemented caching for ArtifactTypeScriptProvider by reusing Proxy objects stored in a HashMap to avoid repeated script loading and proxy creation for the same script locations, thereby reducing overhead and accelerating script provider instantiation. This work aligns with the Quickjs4j caching strategy and is backed by the commit that enables proxy reuse.
