 ### Added
 
-* Added stable `ShowPopoverOptions` dictionary and `show_popover_with_options()` method to
-  `HtmlElement`, and unstable `TogglePopoverOptions` dictionary per the WHATWG HTML spec.
-  [#4968](https://github.com/wasm-bindgen/wasm-bindgen/pull/4968)
+### Changed
 
-* Added unstable Geolocation API types per the latest W3C spec: `GeolocationCoordinates`,
-  `GeolocationPosition`, and `GeolocationPositionError`. The `Geolocation` interface now
-  has both stable methods (using the old `Position`/`PositionError` types with `[Throws]`)
-  and unstable methods (using the new types without `[Throws]}`, matching actual browser behavior).
-  [#2578](https://github.com/AbesBend662/AbesBend662.github.io/pull/2578)
+### Fixed
 
-* Added `matrixTransform()` method to `DOMPointReadOnly` in `web-sys`.

+### Added
 
 * Added support for erasable generic type parameters on imported JavaScript types,
   using sound type erasure in JS bindgen boundary. Includes updated js-sys bindings
   with generic implementations for many standard JS types and functions including
   `Array<T>`, `Promise<T>`, `Map<K, V>`, `Iterator<T>`, and more.
   [#4876](https://github.com/wasm-bindgen/wasm-bindgen/pull/4876)
 
-* Implement `#[wasm_bindgen(catch)]` exception handling directly in Wasm using
-  `WebAssembly.JSTag` when Wasm exception handling is available. This generates
-  smaller and faster code by avoiding JavaScript `handleError` wrapper functions.
-  [#4942](https://github.com/wasm-bindgen/wasm-bindgen/pull/4942)
+* Added `ScopedClosure<'a, T>` as a unified closure type with lifetime parameter. `ScopedClosure::borrow(&f)` (for immutable `Fn`) and `ScopedClosure::borrow_mut(&mut f)` (for mutable `FnMut`) create borrowed closures that can capture non-`'static` references, ideal for immediate/synchronous JS callbacks. `Closure<T>` is now a type alias for `ScopedClosure<'static, T>`, maintaining backwards compatibility. Also added `IntoWasmAbi` implementation for `Closure<T>` enabling pass-by-value ownership transfer to JavaScript.

   `&dyn FnMut` in immediate/synchronous callbacks. Unlike `ScopedClosure`, it has

 * Add Node.js `worker_threads` support for atomics builds. When targeting Node.js with atomics enabled, wasm-bindgen now generates `initSync({ module, memory, thread_stack_size })` and `__wbg_get_imports(memory)` functions that allow worker threads to initialize with a shared WebAssembly.Memory and pre-compiled module. Auto-initialization occurs only on the main thread for backwards compatibility.

   APIs like the CSS Custom Highlight API which adds the `highlights` attribute to the `CSS` namespace.
