#### Fixed

- Make `fetch::JsonError` public.

## v0.9.1

- Fix: `serde-wasm-bindgen` feature.

## v0.9.0

- [BREAKING] Base path changed from `Rc<Vec<String>>` to `Rc<[String]>`.
  It means also `Orders::clone_base_path` returns a slice.
- [BREAKING] Hid markdown functionality behind optional `markdown` feature
- [BREAKING] Added argument `Option<&Namespace>` to functions `Node::from_html` and `El::from_html`.
- [BREAKING] Added blanket `impl<Ms, T: IntoNodes<Ms>> IntoNode<Ms> for Option<T>`.
  This might conflict with local `impl`s of `IntoNodes`, but should make those unnecessary and safe to remove.
- [BREAKING] Removed the deprecated `browser::service::fetch` module.
- [BREAKING] `fetch::Error::SerdeError` changed to `fetch::Error::JsonError`
- Fixed: Prevent link listener from intercepting links with the `download` attribute.
- Fixed an issue in vdom where inputs with invalid contents being cleared on Firefox.
- Added helpers for wheel event: `wheel_ev` and `to_wheel_event`.
- Added `Response::blob`
- Added `panic-hook` feature, enabled by default, to conditionally include `console_error_panic_hook`
- Added macro `raw_svg!` (#589).
- Added `browser::dom::Namespace` to `prelude`.
- Added `At::Role` variant.
- Added `Response::headers`.
- Added `Headers::new`.
- Added `Header::name()` and `Header::value()`.
- Added `fetch::form_data::FormData` and `Request.form_data`.
- Added `serde-wasm-bindgen` and `serde-json` features to use either `serde-wasm-bindgen` or `serde_json` for JSON de-/serialization.
  `serde-wasm-bindgen` reduces final binary size for downstream users.`serde-json` is enabled by default.
- Added method to return detailed error response from server with `FetchError`.
- Added `Request.body_ref` to take the body by reference.
- Added `sl_input` to the `custom_elements` example.
- Added examples `drag_and_drop`, `record_screen`, `e2e_encryption` and `counters`.
- Added `charts` example.
- Added `page_trait` example.
- Added `on_insert` event on elements, triggered when they are inserted into the DOM.
- Implemented `AsAtValue` for `Option<T>`
- Implemented `From<impl AsRef<web_sys::Headers>>` for `Headers`.
- Implemented `FromIterator<(impl Into<Cow<'a, str>>, impl Into<Cow<'a, str>>)>` for `Headers`.
- Use `wheel_ev` in `canvas` example to zoom rectangle with mouse scroll wheel.
- Derived `Eq` and `PartialEq` for `Header`.
- Element macros like `div!` can now contain `Iterator`s inside of `Option` values. Previously only one or the other was possible.
- Adapted to Rust 1.60.0.
