Druid v0.6.0 Release Notes

Release Date: 2020-06-01 // over 2 years ago
  • Highlights

    X11 backend for druid-shell.

    ๐Ÿ‘ [@crsaracco] got us started and implemented basic support to run druid on bare-metal X11 in [#599]. โž• Additional features got fleshed out in [#894] and [#900] by [@xStrom] and in [#920], [#961], and [#982] by [@jneem].

    ๐Ÿง While still incomplete this lays the foundation for running druid on Linux without relying on GTK.

    ๐ŸŒ Web backend for druid-shell.

    ๐ŸŒ [@elrnv] continued the work of [@tedsta] and implemented a mostly complete web backend via WebAssembly (Wasm) in [#759] and enabled all druid examples to ๐Ÿ’ป run in the browser.

    ๐Ÿ”Š While some features like the clipboard, menus or file dialogs are not yet available, all fundamental features are there.

    ๐ŸŽ Using Core Graphics on macOS.

    ๐Ÿ‘ [@cmyr] continued the work of [@jrmuizel] and implemented Core Graphics support for Piet in piet#176.

    Those changes made it into druid via [#905]. ๐ŸŽ This means that druid no longer requires cairo on macOS and uses Core Graphics instead.
