## [0.13.4] - 2024-09-05

### Breaking Changes 🛠
- Updated to web_sys 0.3.70 which unfortunately is breaking some things.
- `use_clipboard` doesn't need the unstable flags anymore.
- `use_locale` now uses `unic_langid::LanguageIdentifier` and proper locale matching (thanks to @mondeja).
- Removed `UseMouseEventExtractorDefault` and reworked `UseMouseCoordType` (thanks to @carloskiki)
- `use_preferred_dark` and `use_color_mode` now try to read the `Sec-CH-Prefers-Color-Scheme` header in SSR. This brings
the necessity to enable an additional feature for them (`axum` / `actix` / `spin`).
### Fixes 🍕

## [0.11.2] - 2024-07-30

### New Functions 🚀
- `use_locale` (thanks to @BrandonDyer64)
- `use_locales` (thanks to @BrandonDyer64)
- `header` – Standard implementations for reading a header on the server.
## [0.11.0] - 2024-07-27
### New Functions 🚀
- `use_user_media`
### New Features 🚀
- Codecs:
- All codecs now live in their own crate `codee`
- There are now binary codecs in addition to string codecs.
- `FromToBytesCodec`
- `WebpackSerdeCodec`
- `BincodeSerdeCodec`
- `ProstCodec` (see also the section "Breaking Changes 🛠" below)
- Every binary codec can be used as a string codec with the `Base64` wrapper which encodes the binary data as a
base64
string.
- This required feature `base64`
- It can be wrapped for example like this: `Base64<WebpackSerdeCodec>`.
- There is now an `OptionCodec` wrapper that allows to wrap any string codec that encodes `T` to encode `Option<T>`.
- Use it like this: `OptionCodec<FromToStringCodec<f64>>`.
- `ElementMaybeSignal` is now implemented for `websys::HtmlElement` (thanks to @blorbb).
- `UseStorageOptions` now has `delay_during_hydration` which has to be used when you conditionally show parts of
the DOM controlled by a value from storage. This leads to hydration errors which can be fixed by setting this new
option to `true`.
- `cookie::SameSite` is now re-exported
- Changing the signal returned by `use_cookie` now tries and changes the headers during SSR.
- New book chapter about codecs
- The macro `use_derive_signal!` is now exported (thanks to @mscofield0).
### Breaking Changes 🛠
- `UseStorageOptions` and `UseEventSourceOptions` no longer accept a `codec` value because this is already provided as a
generic parameter to the respective function calls.
- Codecs have been refactored. There are now two traits that codecs implement: `Encoder` and `Decoder`. The
trait `StringCodec` is gone. The methods are now associated methods and their params now always take references.
- `JsonCodec` has been renamed to `JsonSerdeCodec`.
- The feature to enable this codec is now called `json_serde` instead of just `serde`.
- `ProstCodec` now encodes as binary data. If you want to keep using it with string data you can wrap it like
this: `Base64<ProstCodec>`.
- All of these structs, traits and features now live in their own crate called `codee`
- A bunch of new codecs are available. Have a look at the docs for crate `codee`.
- `use_websocket`:
- `UseWebsocketOptions` has been renamed to `UseWebSocketOptions` (uppercase S) to be consistent with the return
type.
- `UseWebSocketOptions::reconnect_limit` and `UseEventSourceOptions::reconnect_limit` is now `ReconnectLimit`
instead
of `u64`. Use `ReconnectLimit::Infinite` for infinite retries or `ReconnectLimit::Limited(...)` for limited
retries.
- `use_websocket` now uses codecs to send typed messages over the network.
- When calling you have give type parameters for the message type and the
codec: `use_websocket::<String, WebpackSerdeCodec>`
- You can use binary or string codecs.
- The `UseWebSocketReturn::send` closure now takes a `&T` which is encoded using the codec.
- The `UseWebSocketReturn::message` signal now returns an `Option<T>` which is decoded using the codec.
- `UseWebSocketReturn::send_bytes` and `UseWebSocketReturn::message_bytes` are gone.
- `UseWebSocketOptions::on_message` and `UseWebSocketOptions::on_message_bytes` have been renamed
to `on_message_raw` and `on_message_raw_bytes`.
- The new `UseWebSocketOptions::on_message` takes a `&T`.
- `UseWebSocketOptions::on_error` now takes a `UseWebSocketError` instead of a `web_sys::Event`.
- `use_storage` now always saves the default value to storage if the key doesn't exist yet.
- Renamed `BreakpointsSematic` to `BreakpointsSemantic` and `breakpoints_sematic` to `breakpoints_semantic`
(note the `n`) (thanks to @mondeja).
### Fixes 🍕
- Fixed auto-reconnect in `use_websocket`
- Fixed typo in compiler error messages in `use_cookie` (thanks to @SleeplessOne1917).
- Fixed potential signal out of scope issue with `use_raf_fn`
### Other Changes 🔥

- Better CI/CD (thanks to @EstebanBorai).

### Breaking Changes 🛠
- The `leptos` version is now 0.6
- The trait `Codec` has been renamed to `StringCodec` and has been moved to `util::StringCodec`.
- The struct `StringCodec` has been renamed to `FromToStringCodec` and has been moved to `util::FromToStringCodec`.
- The structs `JsonCodec` and `ProstCodec` have been moved to `util` as well.
- The function `use_storage` now requires type parameters for the stored type and the codec like all the other
`...storage...` functions.
### Fixes 🍕
- Fixed `use_geolocation` SSR compile issue
- Fixed `use_intl_number_format` maximum fraction digits option
### Changes 🔥
- The `UseMouseReturn` signals `x`, `y`, and `source_type` are now of type `Signal<f64>` instead of `ReadSignal<f64>`.
- You can now convert `leptos::html::HtmlElement<T>` into `Element(s)MaybeSignal`. This should make functions a lot
easier to use in directives.
- There's now a chapter in the book especially for `Element(s)MaybeSignal`.
- Throttled or debounced callbacks (in watch\__ or _\_fn) no longer are called after the containing scope was cleaned
up.
- The document returned from `use_document` now supports the methods `query_selector` and `query_selector_all`.
## [0.9.0] - 2023-12-06
### New Functions 🚀
- `use_display_media` (thanks to @seanaye)
### Breaking Changes 🛠
- (@feral-dot-io) The use `use_<type>_storage` functions have been rewritten to use `Codec`s instead of always
requiring `serde`.
- This also removes the feature `storage`
- By default the `StringCodec` is used which relies on types implementing `FromString + ToString`
- If you want to use `JsonCodec` you have to enable the feature `serde`
- If you want to use `ProstCodec` (new!) you have to enable the feature `prost`.
- (@feral-dot-io) The Rust flag `--cfg=web_sys_unstable_apis` is not needed anymore since relevant `web_sys` APIs are
now stable.
This affects in particular
- `use_element_size`
- `use_resize_observer`
### Fixes 🍕
- `use_raf_fn` and `use_timestamp` no longer spam warnings because of `get`ting signals outside of reactive contexts.
- `use_infinite_scroll` no longer calls the callback twice for the same event
- `use_scroll` now uses `try_get_untracked` in the debounced callback to avoid panics if the context has been destroyed
while the callback was waiting to be called.
- `use_idle` works properly now (no more idles too early).
- `use_web_notification` doesn't panic on the server anymore.
