# Smithay Changelog
## Unreleased
### Additions
#### Clients & Protocols
- Added public api constants for the roles of `wl_shell_surface`, `zxdg_toplevel` and `xdg_toplevel`. See the
`shell::legacy` and `shell::xdg` modules for these constants.
- Whether a surface is toplevel equivalent can be determined with the new function `shell::is_toplevel_equivalent`.
- Setting the parent of a toplevel surface is now possible with the `xdg::ToplevelSurface::set_parent` function.
- Add support for the zxdg-foreign-v2 protocol.
### Bugfixes
- EGLBufferReader now checks if buffers are alive before using them.
## 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
