version 0.3.0 (2021-07-25)

Large parts of Smithay were changed with numerous API changes. It is thus recommended to
approach version 0.3 as if it was a new crate altogether compared to 0.2.

The most notable changes are:

- Deep refactor of the graphics backends around a workflows centered on allocating graphics buffers,
  and a Gles2-based renderer abstraction is provided.
- Support for DRM atomic modesetting as well as client-provided DMABUF
- Most backends are now `calloop` event sources generating events. The recommended organization for
  your smithay-based compositor is thus to centralize most of your logic on a global state struct,
  and delegate event handling to it via the shared data mechanism of `calloop`. Most of the callbacks
  you provide to Smithay are given mutable access to this shared data.
- The `wayland::compositor` handling logic now automatically handles state tracking and delayed commit
  for wayland surfaces.

Many thanks to the new contributors to Smithay, who contributed the following:

- Support for [`libseat`](https://sr.ht/~kennylevinsen/seatd/) as a session backend, by
  @PolyMeilex
- Support for graphics tablets via the `tablet` protocol extension, by @PolyMeilex
- Support for running Smithay on `aarch64` architectures, by @cmeissl
- A rework of the `xdg-shell` handlers to better fit the protocol logic and correctly track configure
  events, by @cmeissl
- Basic Xwayland support, by @psychon
