+title: Released Cyclone Scheme 0.16
+excerpt: This release contains bug fixes and improvements for freeing memory allocated for Opaque C objects.
+---
+
+Features
+
+- Updated the C API to optionally allow Cyclone's GC to free memory pointed to by an Opaque object. 
+
+  For example:
+
+      my_c_obj = calloc(1, sizeof(*my_c_obj_type));
+      make_c_opaque(opq, my_c_obj);
+      opaque_collect_ptr(&opq) = 1; // Cyclone's GC will free this memory
+
+Bug Fixes
+
+- Fixed a bug in `read-bytevector` where an extra byte could be introduced when reading multiple chunks of data.
+- Fixed a bug where variables defined within `define-syntax` and `let-syntax` are reported as unbound by the compiler.
