✨ Highlights in Slint 1.17

🖥 Making Slint desktop-ready

This release adds the building blocks that desktop apps expect:

• 🤏 Drag and drop — new DragArea and DropArea elements and a data-transfer type. See the drag-and-drop guide. Try dragging data between elements — and to/from other apps.
• 🔔 System tray — new SystemTrayIcon element. Add a tray icon and menu and check it on Linux, macOS, and Windows.
• 💬 Tooltips — new Tooltip element. Drop one inside any element and hover.
• 🔘 Radio group — new RadioGroup widget, with static or for-generated RadioButton children.
• …plus minimized / maximized / close() / hide() on Window.

📐 Language & widgets

• 🔁 Two-way bindings to model row data — bind directly to a row and edit in place (e.g. a TextInput bound to a row's field).
• ↔️ cross-axis-alignment on VerticalLayout and HorizontalLayout

🛠 Tooling

• 📱 Remote Slint viewer — run slint-viewer --remote on your machine and connect from a phone or another device to preview live; the viewer now also runs on iOS and Android.
• 🤖 MCP server & AI skills — introspect and drive your running UI from AI assistants

⚡ Node.js

• Faster event loop — integrates with libuv on Linux and macOS to avoid excessive polling.

🎁 And more

• 🤖 C++ on Android — build and run C++ Slint apps on Android. See the Android guide.
• 📝 Markdown in native code — StyledText functions to parse markdown at runtime in Rust, C++, JavaScript, and Python.
• 🎨 Render into an external WGPU texture — new SkiaWGPURenderer (WGPU upgraded to 29).
• 🌈 Drop shadow & gradient improvements — per-corner shadow radii, inner-shadow-*, and at <x> <y> + radius for @conic-gradient / @radial-gradient.
• 🪶 Flickable animation polish — animated wheel scrolling plus focus and selection fixes.

…and many more fixes — see the full ChangeLog.
