### Added
- `image::Handle` type with `from_path` and `from_memory` methods. [#90]
- `image::Data` enum representing different kinds of image data. [#90]
+- `text_input::Renderer::measure_value` required method to measure the width of a `TextInput` value. [#108]
+- Click-based cursor positioning for `TextInput`. [#108]
+- `Home` and `End` keys support for `TextInput`. [#108]
+- `Ctrl+Left` and `Ctrl+Right` cursor word jump for `TextInput`. [#108]
+- `keyboard::ModifiersState` struct which contains the state of the keyboard modifiers. [#108]
+- `TextInput::password` method to enable secure password input mode. [#113]
### Changed
- `Image::new` takes an `Into<image::Handle>` now instead of an `Into<String>`. [#90]
- `Button::background` takes an `Into<Background>` now instead of a `Background`.
+- `keyboard::Event::Input` now contains key modifiers state. [#108]
### Fixed
- `Image` widget not keeping aspect ratio consistently. [#90]
+- `TextInput` not taking grapheme clusters into account. [#108]
