Outside News

0.6.0 - 2020-06-01

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.
