### Added

 - The StandardListView provides now a set-current-item function to set the selected item and bring it into view.

## [0.3.4] - 2023-01-25

### Changed

 - A new syntax is available that declares the components with `component Xxx { ... }`  instead of `Xxx := ...`.
   The old syntax continues to work in this release.
 - A warning is shown when calling non-pure function or callback from pure context (eg: a property binding).
   Callbacks and functions can be annotated with `pure`.
 - On an `Image`, the default value of `source-clip-width` and `source-clip-height` is now set to
   the size of the image minus the `source-clip-{x,y}`. The source clip size is now used to compute
   the default aspect ratio of the image.
 - Deprecated `invoke_callback` functions in the slint interpreter in favor of `invoke`, which can also
   invoke functions in addition to callbacks.
 - Warn if the last component or singleton in a file is implicitly marked for exporting.

### Added

 - `StandardTableView` widget.
 - LSP: support of Slint features (auto-complete, preview, ...) in `slint!{}` macro in Rust files.
 - The software renderer can now load fonts at run-time, without the need to pre-render glyphs
   at compile time.
 - The preview in the online editor, VS Code extension, and the VS Code web extension highlight
   components while the cursor is on the component type name.

### Fixed

 - Compiler panic for files containing no component (#2005).
 - Calling public functions from native code.
 - Fixed crash when using repeaters in C++ on 32-bit architectures.
 - Conversion of array literal containing struct with array literal (#2023).
 - Structs exported by the main file are always generated in native code (#594).

 - VSCode and online editor: Added UI to edit and remove property bindings.

### Fixed

 - Fixed privacy rules in global properties. #1951
 - Fixed drawing of images with the software renderer.
 - Fixed `visible` property on element with drop shadow. #1460

## [0.3.2] - 2022-11-28

### Changed

 - When using a two way binding `foo <=> bar`, the default value will always be the one of `bar`.
   There was a warning about this change in previous versions (#1394).
 - Disallow overrides or duplicated declarations of callbacks. Previously they were silently overwritten,
   now an error is produced.
 - The name `init` is now a reserved name in callbacks and properties.
 - In the interpreter, calling `set_property` or `get_property` on properties of the base returns an error.
 - Deprecated `slint::WindowEvent` and `slint::PointerEventButton` and moved them to the `slint::platform` module.
 - Renamed the `Keys` namespace for use in `key-pressed`/`key-released` callbacks to `Key`. The
   old name continues to work.
 - The style or the backend now always set a value for the `Window`'s `default-font-size` property.
 - In the Rust API, the `GraphicsAPI`'s `NativeOpenGL` variant uses a function signature for `get_proc_address` that
   takes a `&std::ffi::CStr` instead of a `&str` to match the native APIs and avoid unnecessary conversions.

### Added

 - Added new `material` style based on Material Design, with `material-light` and `material-dark` as variants.
 - Added `Window::is_visible` in Rust and C++.
 - Added `From<char>` for `SharedString` in Rust.
 - Added `KeyPressed` and `KeyReleased` variants to `slint::WindowEvent` in Rust, along
   with `slint::platform::Key`, for use by custom platform backends.
 - Added support for the implicitly declared `init` callback that can be used to run code when
   an element or component is instantiated.
 - Properties can be annotated with `in`, `out`, `in-out`, or `private`.
 - Transitions can now be declared directly within the state.
 - Online editor: The property view can now edit properties.
 - LSP preview: When the cursor is on the name of an element, the element's location is highlighted in the preview.
 - LSP: Added a setting to change the style and the include paths.
 - VSCode extension: added the property view.
 - Added `rem` as unit that represents a relative font size and is multiplied with the `Window.default-font-size` when used.
 - Added `relative-font-size` as type that holds values of `rem`.

### Fixed

 - Fluent style: SpinBox gets focus when buttons are clicked.
 - Software renderer: Fix drawing the background color.

 - Switch to yeslogic-fontconfig-sys from servo-fontconfig dependency. This allows for fontconfig
   to be a run-time dependency via dlopen.
 - Skia renderer: Improvements to text input.

### Added

 - Added `slint::FilterModel`, `slint::MapModel` to the C++ API.
 - Added `slint::SortModel` to Rust and C++ API.
 - Added `VecModel::extend` and `VecModel::extend_from_slice`.
 - Online editor: Added "Properties" and "Outline" tabs.
 - Added initial support for input methods with pre-edit text.
 - Added a dark theme for the Fluent style, which is automatically selected if the system
   color scheme is dark.
 - Added `fluent-light` and `fluent-dark` as explicit styles to select a light/dark variant,
   regardless of the system color scheme setting.

### Fixed

 - TextInput now shows the text mouse cursor.
 - In Flickable, added a small delay before passing the Press pointer event to the children.
 - Online editor: Fixed "go to definition" across files.
 - Fixed a panic in the slint compiler when visiting layout properties for loop analysis (#1659).

## [0.2.0] - 2022-02-10

This version changes some APIs in incompatible ways. For details how to migrate your application code, see the [C++ migration guide](api/cpp/docs/cpp_migration.md)
as well as the [Rust migration guide for the `sixtyfps` crate](api/rs/slint/migration.md) and for the
[`slint-interpreter` crate](internal/interpreter/migration.rs).

### Changed

 - Minimum rust version is now 1.56
 - C++ compiler requires C++20
 - In the C++ interpreter API `std::span` is used for callbacks arguments, instead of `sixtyfps::Slice`
 - `Model::row_data` will now return a `Option<T>` / `std::optional<T>` instead of a plain `T`.
 - `Model::model_tracker` no longer has a default implementation.
 - The deprecated methods `Model::attach_peer` and `ModelNotify::attach` were removed.
 - The interpreter does not differentiate anymore between `Value::Array` and `Value::Model`
   everything is a `Value::Model`, which now contains a `ModelRc`
 - In Rust, `slint::SharedPixelBuffer` and `slint::SharedImageBuffer` now use a `u32` instead of `usize` for `width`, `height` and `stride`.
 - In Rust and C++, `slint::Image::size()` now returns an integer size type.
 - `sixtyfps::interpreter::CallCallbackError` was renamed to `slint::interpreter::InvokeCallbackError`
 - Some deprecation warning in .60 became hard errors
 - Replace `ModelHandle` with `ModelRc`
 - `slint::interpreter::ComponentInstance` in Rust now implements `slint::ComponentHandle`. This removes `sixtyfps_interpreter::WeakComponentInstance` in favor
   of `slint_interpreter::Weak<slint_interpreter::ComponentInstance>`.
 - For the Rust API crate, the Rust Interpreter API crate, the `backend-gl`, `x11`, and `wayland` features were renamed to `backend-gl-all`, `backend-gl-x11`, and `backend-gl-wayland`.
 - For the C++ CMake interface, the `SIXTYFPS_BACKEND_GL`, `SIXTYFPS_FEATURE_X11`, and `SIXTYFPS_FEATURE_WAYLAND` options were renamed to `SLINT_BACKEND_GL_ALL`, `SLINT_FEATURE_BACKEND_GL_X11`, and `SLINT_FEATURE_BACKEND_GL_WAYLAND`.
 - The animation `loop-count` property was replaced by `iteration-count` (which is the same as `loop-count` plus one)

### Added

 - `TextEdit::font-size` and `LineEdit::font-size` have been added to control the size of these widgets.
 - Added `slint::Window::set_rendering_notifier` to get a callback before and after a new frame is being rendered.
 - Added `slint::Window::request_redraw()` to schedule redrawing of the window contents.

### Fixed

 - Models initialized from arrays are now also mutable when run in the interpreter.
 - Fixed compilation error when accessing object members of array through the array index syntax

## [0.1.6] - 2022-01-21

### Changed

 - **Breaking:** The internal key code for the keys left, right, home and end
   has changed. This was undocumented, but if you were handling this in the
   `FocusScope` event, these keys will now be ignored. Use the `Keys.LeftArrow`
   and other code exposed in the `Keys` namespace instead.
 - For `sixtyfps::Timer` (C++ and Rust), it's now possible to call `restart()` after
   a timer has been stopped previously by calling `stop()`.
 - Property access in `.60` was optimized by doing more constant propagation.

### Added

 - Color names can now be accessed through the `Colors` namespace (in `.60`).
 - Math function are now available through the `Math` namespace (in `.60`).
 - `TouchArea` gained a `mouse-cursor` property to change the mouse cursor.
 - C++: Added `SIXTYFPS_VERSION_MAJOR`/`SIXTYFPS_VERSION_MINOR`/`SIXTYFPS_VERSION_PATCH` version macros.
 - More special keyboard key codes are provided in the `FocusScope`, and
   special keys are handled
 - `start()`, `stop()`, `running()` and a default constructor for C++ `sixtyfps::Timer`
 - Added math functions `log`, and `pow`.
 - Property animations now have a `delay` property, which will delay the start
   of the animation. Use this to create sequential animations.
 - Rust: Added `sixtyfps::VecModel::insert(&self, index, value)`.
 - C++: Added `sixtyfps::VecModel::insert(index, value)`.
 - Added ability to access elements of a model with the `[index]` syntax.

### Fixed

 - Memory leak in C++.
 - Native style: Colors are updated automatically when the Windowing system switches to and from dark mode (#687)
 - Ctrl/Command+X in text fields copies the selected text to the clipboard and deletes it (cut).
 - Improved native ComboBox look.
 - Fixed panics or compilation error when using two way bindings on global properties.
