Dear community: This is a call for vote to release apache-tvm-ffi version v0.1.14. The main highlights of this release are
* Structural transformation APIs — StructuralMutator recursively transforms reflected object graphs, with structural_map providing a typed callback interface for compiler passes, alongside maybe_inplace_mutate and var_remap. This completes the structural family next to the existing equality, hashing, and walking APIs. C++ StructuralMap callbacks accept flexible return types: a replacement value, Expected<T>, Error/Unexpected, or a thrown Error, and match before recursive descent so unmatched nodes skip remap lookup and callback-chain work. * Opaque pointer handler map — third-party extension types that cannot define or accept monkey-patching of __tvm_ffi_opaque_ptr__ can now participate in opaque-pointer conversion via tvm_ffi.core._OPAQUE_PTR_HANDLERS, without changing their owning package. * Stronger static typing through Any — static object type bounds are now propagated across ObjectPtr, ObjectRef, and raw-object conversions into Any and AnyView, while runtime validation for unconstrained values is unchanged. * Rust structural and object binding support — all four structural operations (walk, visit, map, mutate) gain typed callbacks and a #[dispatch(...)] frontend; the object binding runtime adds zero-copy upcasts, identity comparison, and reflection-table method lookup; and containers now hold heterogeneous Any elements. * Safer copy-on-write through unique() — Object::unique() now requires one strong reference AND no external weak references, since a live WeakObjectPtr can still upgrade while a strong owner exists. use_count() keeps its strong-only semantics. * Free-threaded Python cross-builds — Python discovery now separates the host interpreter running Cython from the target development artifacts, unblocking 3.14t wheel builds on cross-compiled platforms such as Linux PPC64LE and macOS ARM64. * Correctness fixes — Python annotation metadata is stabilized across versions, and ffi.Error is now picklable so FFI-originated exceptions survive round-tripping.
