## [0.12.0] - 2026-05-26
### Breaking Changes
- Added import attributes to the Loader trait #[601](https://github.com/DelSkayn/rquickjs/pull/601)
- Added half support (f16) for Float16Array # [662](https://github.com/DelSkayn/rquickjs/pull/662)
- `Value::new_big_int` now returns `Result<Value>` so QuickJS allocation failures are surfaced to the caller #[585](https://github.com/DelSkayn/rquickjs/issues/585)
### Added
- Added `#[qjs(prop)]` method attribute to declare a JS data property on a class prototype.
Unlike `#[qjs(get)]`, which generates an accessor and requires a `FromJs<Self>` receiver,
`prop` is evaluated at class registration time and emits a plain data descriptor (matching
Web IDL semantics for `@@toStringTag`, `@@species`, etc.). Honours `rename`, `configurable`,
`enumerable`, and a new `writable` flag (which also gates `writable` on `prop`).
- Added `FromJs` and `IntoJs` derive macros for plain-data structs
- Added `RQUICKJS_SYS_NO_WASI_SDK` env variable that skips downloading and setting up the WASI SDK when set to `1` #[648](https://github.com/DelSkayn/rquickjs/pull/648)
- Added `Object::new_proto` for creating objects with a custom or null prototype #[572](https://github.com/DelSkayn/rquickjs/issues/572)
- Added `Symbol::new`, `Symbol::with_description`, and `Symbol::new_global` for creating local and global symbols from Rust #[672](https://github.com/DelSkayn/rquickjs/pull/672)
- Added `ArrayBufferSource` trait and `ArrayBuffer::from_source` / `from_source_shared` / `from_source_immutable` safe constructors for wrapping external, caller-owned buffers, with built-in impls for `Vec<u8>`, `Box<[u8]>`, `Arc<[u8]>`, `Arc<Vec<u8>>`, and (behind the `bytes` feature) `bytes::Bytes`
- Add pre-generated bindings for `armv7-unknown-linux-gnueabihf`
- Add pre-generated bindings for `powerpc64-unknown-linux-gnu`
### Changed
- Bump MSRV to 1.87
- Updated `AsyncContext::async_with` to use async closure syntax #[602](https://github.com/DelSkayn/rquickjs/pull/602)
### Deprecated
- Deprecated `async_with!` macro #[602](https://github.com/DelSkayn/rquickjs/pull/602)
### Fixed
- Fixed `Property::configurable()` / `.writable()` / `.enumerable()` not emitting `JS_PROP_HAS_*` flags, so redefining an existing property silently kept its old attributes #[693](https://github.com/DelSkayn/rquickjs/issues/693)
- Fixed QuickJS rope strings (`JS_TAG_STRING_ROPE`) not being recognized as strings, causing `type_of()`, `is_string()`, and `as_string()` to fail on large concatenated strings
- Fixed interrupt handler causing GC assertion failure due to missing `JS_DupContext` on error context from `JS_ExecutePendingJob` #[664](https://github.com/DelSkayn/rquickjs/pull/664)
- Fixed cross-thread stack overflow false positives in parallel mode by updating stack baseline before QuickJS C entry points
- Fixed promise polling not returning Ready variant when exception occurs
- Fixed promise future aborting on stale pending exceptions by only bailing on uncatchable errors (e.g. interrupt handler)
- Fixed iterators to use correct IteratorPrototype chain
- Fixed a latent ABI layout vulnerability in `JS_NewPromiseCapability` FFI boundary by replacing tuple with strictly compatible array
- `#[rquickjs::class]` now rejects fields whose type implements `JsClass` with a clear compile error; such fields silently dropped nested mutations because the generated getter cloned the value. Wrap the field in `Class<'js, T>` instead #[532](https://github.com/DelSkayn/rquickjs/issues/532)
- Added missing `Trace` implementations for `Constructor`, `Promise`, `Proxy`, `ArrayBuffer`, and `TypedArray`; added `JsLifetime` for `Proxy`; re-exported `Constructor` at the crate root
- Fixed `#[qjs(static, rename = PredefinedAtom::...)]` methods failing when the target symbol exists as a non-writable property on `Function.prototype` (e.g. `Symbol.hasInstance`) by defining properties directly on the constructor instead of going through the prototype chain #[315](https://github.com/DelSkayn/rquickjs/issues/315)
- Fixed `#[qjs(static, get/set)]` accessors being placed on the class prototype instead of the constructor #[478](https://github.com/DelSkayn/rquickjs/issues/478)
- Fixed `Runtime::set_max_stack_size` crashing on large values (e.g. `usize::MAX`) by clamping to avoid a pointer underflow inside QuickJS's stack limit check #[437](https://github.com/DelSkayn/rquickjs/issues/437)

## [0.9.0] - 2025-01-29
### Breaking Changes
- Switching to quickjs-ng from quickjs as base engine #[369](https://github.com/DelSkayn/rquickjs/pull/369)
This change should bring better performances and features, we are aware that it is bigger in intruction sizes.
We would eventually like to support the "original" quickjs engine again in the future, but we use new functions now that are only available in the `-ng` version.
