✨ 0.7.1 (2021-12-15)

🛠 Fixes

✨ 0.7.0 (2021-12-08)

Release post: https://sycamore-rs.netlify.app/news/announcing-v0.7.0

⚡️ Features
- Implement TryFromSegments for T: Route. This allows the creation of nested routers. See the docs for more information about usage.
- Make parenthesis optional in cloned! macro. The following syntax is now accepted, in addition to the old syntax:
```
// Before
cloned!((my, variables, to, clone) => move || { ... })
// After
cloned!(my, variables, to, clone => move || { ... })
```
- Builder API. Check out the hello-builder example for more usage details.
- Make wasm-bindgen-interning a feature. This feature is enabled by default but can be opted-out which would disable wasm-bindgen/enable-interning. Opting-out can lead to a slight decrease in binary size at the cost of performance.
- Introduce render_get_scope function. This allows accessing (and disposing of) the ReactiveScope created by the render function.
- Hydration support. To enable hydration, replace calls to render and render_to with hydrate and hydrate_to.
- Add #[track_caller] to use_context. This makes it much easier to debug the "context not found for type" error.
- Better debugging utilities for inspecting the ReactiveScope hierarchy.
🛠 Fixes
📃 Documentation
- Add a note in the docs about Trunk CSS support.
- Fix typo in README.md.
Internal
🚨 BREAKING CHANGES
- Refactor GenericNode and introduce Html trait. Add IS_BROWSER constant to Html.. For projects that target HTML, it is recommended to use the Html trait instead of GenericNode. This will ensure that it cannot be used on rendering backends that are not for HTML. To check if code is executing on the browser, access the Html::IS_BROWSER constant on the generic rendering backend. This also slightly changes the GenericNode interface which is why it is a breaking change but would most likely not influence you.
- Make GenericNode generic over the event type. The event type is now an associated type to allow rendering backends to use another type from web_sys::Event.
- Rename Template to View and template! to view!. For most cases, a simple search-and-replace will suffice, replacing all instances of Template to View and all instances of template! to view!.
- Rename StateHandle to ReadSignal. The old name was somewhat confusing and did not reflect that StateHandle was just a read-only signal.

✨ 0.6.3 (2021-10-10)

🛠 Fixes
- Respect basename when navigating using router.

✨ 0.6.2 (2021-10-09)

⚡️ Features
- Add GenericNode::remove_property method.
- Add node! macro for creating a single node.
🛠 Fixes
- Do not strip leading / from pathname. This fixes an issue with the router on Firefox when navigating to the index page.
Internal
- Remove ToTokens impl for TagName.

✨ 0.6.1 (2021-09-25)

🛠 Fixes
📃 Documentation
- Update docs to use boolean for disabled attribute on button.
- Add documentation on topological dependency tracking.

✨ 0.6.0 (2021-09-12)

Release post: https://sycamore-rs.netlify.app/news/announcing-v0.6.0

⚡️ Features
- Add integrations for sycamore-router.
- Added dangerously_set_inner_html special attribute to html elements. This allows directly setting an element's inner html without going through a NodeRef and manually calling .set_inner_html().
- Implement Portals. Portals allow adding nodes to elements that are in another tree.
- Allow instantiating components with the Component trait. You can now also create components that are generic over another component. This pattern can be seen in the higher-order-components example.
- Respect base html tag in router.
- Dark mode on website!
- create_reducer hook. The create_reducer hook is an alternative to Signal::new. It allows you to use a reducer function to get the next state from the previous state.
```
enum Msg {
    Increment,
    Decrement,
}
let (state, dispatch) = create_reducer(0, |state, msg: Msg| match msg {
    Msg::Increment => *state + 1,
    Msg::Decrement => *state - 1,
});
```
- Opt out of router by using rel="external" on an anchor tag. Adding rel="external" to an anchor tag will use the browser's default navigation behavior.
```
template! {
    a(href="path", rel="external") { "Link" }
}
```
🛠 Fixes
- Fix logic error in reconcile_fragments.
- Fix grammar on website index page.
- Scroll to top when navigating to a page.
- Use ahash instead of default SipHash for better performance.
- Explicitly define MSRV to 1.53 and run CI in a matrix.
- Remove inline JS snippet. This removes the need to load an extra JS file before Sycamore can start.
- Add some UI tests for #[component] attribute macro.
- Generate a sitemap.xml for the website.
- Fix broken link to the reactivity page on the website index page.
- Explain that Trunk needs a index.html file in Hello World docs.
- Remove internal Rc from DomNode. This significantly improves performance and memory usage. See the PR for benchmarks.
- Optimize the website with wasm-opt to reduce binary size.
- Optimize create_effect.
- Fix SsrNode's implementation of remove_child removing two children instead of just one.
- Hold a backlink for each ReactiveScope to its parent scope. This fixes a bug where use_context could only access the context on the first render and would panic on subsequent accesses.
- Remove dependency on chrono. This was replaced with direct access to browser APIs to reduce the number of dependencies and thus to improve build times.
- Replace internal usage of .unwrap() with .unwrap_throw(). Slightly improves binary sizes.
- Derive Clone for sycamore_router path types.
- Update todomvc example with latest features.
- Fix router not actually parsing identifiers. Fixes a bug where a dynamic parameter followed by a dynamic segment would parse as a single segment.
- Build rustdocs in CI. The API documentation for the master branch is available at sycamore-rs.netlify.app/api.
- Reorganize documentation a bit.
🚨 BREAKING CHANGES
- Extract reactive primitives into separate crate sycamore-reactive. Reactive primitives are now re-exported in the sycamore crate to avoid adding new dependencies to your project. It is also now possible to use reactive primitives without using sycamore by directly depending on sycamore-reactive.
- Rename sub-module sycamore::rx to sycamore::reactive. rx might be ambiguous with Rx family of libraries. Renaming to reactive makes it clear that it works differently from Rx libraries.
- Refactored router with new API. See the new documentation for more details.
- Support boolean attributes. Some attributes now expect a bool instead of impl ToString. This also fixes an issue where previously, attributes couldn't be removed directly from the template! macro.
```
// Before
template! {
    input(type="checkbox", checked="") { "Checkbox" }
}
// After
template! {
    input(type="checkbox", checked=true) { "Checkbox" }
}
```

🚨 BREAKING CHANGES
- Abstraction over rendering backend! This introduces the concept of GenericNode which is a trait to access the underlying rendering backend. Currently, Sycamore ships with DomNode and SsrNode out-of-the-box for rendering the the browser DOM and to a static string respectively. Components should now be generic over G: GenericNode to be able to render to multiple backends [@lights0123, #67]
- Require using the #[component(_)] attribute macro for defining components. This changes the component syntax to:
```
#[component(MyComponent<G>)]
fn my_component() -> Template<G> {
    todo!()
}
```
  The #[component(_)] macro generates a struct under the hood that implements the Component trait for improved type safety. This also means that you no longer need #[allow(non_snake_case)] in your code! [@lukechu10, #70] #92]
- Rename Owner to ReactiveScope [@lukechu10, #99]
- Renamed crate from maple-core to sycamore and maple-core-macro to sycamore-macro. Also renamed all instances of "Maple" to "Sycamore" [@lukechu10, #109]
- Rename TemplateResult to Template [@lukechu10, #112]
- Rename reactive sub-module to rx [@lukechu10, #113]
- Remove render functions (render, render_to, render_to_string, etc...) from prelude. These functions are generally only called once in a Sycamore app so they do not belong in the prelude [@lukechu10, #140]

✨ 0.4.3 (2021-04-01)

Changelog

⚡️ Features
- Support '-' in attribute names. This makes the following syntax valid:
```
template! {
    button(aria-hidden="true")

✨ 0.4.0 (2021-03-25)

Changelog

⚡️ Features
- Iteration using SignalVec. This is more of an experiment and there are some bugs. This will most likely be removed in a future version [@lukechu10, #49]
- Keyed iteration using Keyed and non-keyed iteration using Indexed which can iterate over a Signal<Vec>. This is the recommended way to iterate over a list of values [@lukechu10, #51, #53 and #54]
- Node references. Use the ref attribute to bind an HTML element to a NodeRef [@lukechu10, #57]
🛠 Fixes
- Fix debug assertions in Keyed [@lukechu10, #53]
🛠 Internal Fixes and Improvements

🛠 Fixes
- Add some badges to README.md [@lukechu10, #44 and #48]

✨ 0.3.0 (2021-03-13)

Changelog

⚡️ Features
- Nested effects. Inner effects are destroyed and recreated when outer effects re-run [@lukechu10, #29]
- cloned! macro for making it easier to clone items into a new scope [@lukechu10, #34]
- Effects are created inside a reactivity root (using create_root). When the root Owner is dropped, all effects are also destroyed [@lukechu10, 37]
- Nested templates. Using this, it is also possible to build simple if/else control flow although there will be a more polished version [@lukechu10, #41]
🛠 Fixes
- Parse html root as an HtmlTree [@lukechu10, #25]
- Recreate effect dependencies on each re-run [@lukechu10, #29]
🛠 Internal Fixes and Improvements
