 # Changelog
 
+## 2025-11-17 - 5.16.7 - fix(classes.collection)
+Improve Deno and TypeScript compatibility: Collection decorator _svDbOptions forwarding and config cleanup
+
+- Collection decorator: capture original constructor and forward _svDbOptions to ensure property decorator options (serialize/deserialize) remain accessible in Deno environments.
+- Collection decorator: keep instance getter defined on prototype for Deno compatibility (no behavior change, clarifies forwarding logic).
+- Build/config: removed experimentalDecorators and useDefineForClassFields from deno.json and tsconfig.json to avoid Deno/TS build issues and rely on default compilation settings.
+
 ## 2025-11-17 - 5.16.6 - fix(classes)
 Add Deno compatibility, prototype-safe decorators and safe collection accessor; bump a few deps
