Druid v0.6.0 Release Notes

Release Date: 2020-06-01 // almost 4 years ago

  • Highlights

    X11 backend for druid-shell.

    👍 [@crsaracco] got us started and implemented basic support to run druid on bare-metal X11 in [#599]. ➕ Additional features got fleshed out in [#894] and [#900] by [@xStrom] and in [#920], [#961], and [#982] by [@jneem].

    🐧 While still incomplete this lays the foundation for running druid on Linux without relying on GTK.

    🌐 Web backend for druid-shell.

    🌐 [@elrnv] continued the work of [@tedsta] and implemented a mostly complete web backend via WebAssembly (Wasm) in [#759] and enabled all druid examples to 💻 run in the browser.

    🔊 While some features like the clipboard, menus or file dialogs are not yet available, all fundamental features are there.

    🍎 Using Core Graphics on macOS.

    👍 [@cmyr] continued the work of [@jrmuizel] and implemented Core Graphics support for Piet in piet#176.

    Those changes made it into druid via [#905]. 🍎 This means that druid no longer requires cairo on macOS and uses Core Graphics instead.
