# CHANGELOG: wayland-server
## Unreleased
## 0.30.0-beta.13
#### Breaking changes
- `Resource::client_id` has been replaced by `Resource::client` making the owning `Client`
of a `Resource` accessible without a roundtrip to `DisplayHandle`
## 0.30.0-beta.11
#### Bugfixes
- `Weak::upgrade` now checks if the object has been destroyed
## 0.30.0-beta.10
#### Additions
- Introduce `Weak`, a helper type to store resources without risking reference cycles
- Introduce `Proxy::is_alive()` method checking if the protocol object referenced by a resource is still
alive in the protocol state.
#### Bugfixes
- Ensure that `XDG_RUNTIME_DIR` is an absolute path before trying to use it
## 0.30.0-beta.9
#### Additions
- `Client` is now `Clone`
## 0.30.0-beta.8
#### Breaking changes
- `Display::null_id()` has been removed, instead use `ObjectId::null()`.
- The traits `DelegateDispatch` and `DelegeteGlobalDispatch` have been removed, their functionnality being
fused into more generic versions of the `Dispatch` and `GlobalDispatch` traits.
- `DisplayHandle::disable_global()` and `DisplayHandle::remove_global()` now require the state type parameter,
like `create_global`. This is required for compatibility with libwayland 1.21.
- The `socket` module has been flattened into crate root.
#### Additions
- Introduce the `log` cargo feature to control logging behavior.
## 0.30.0-beta.4
#### Breaking changes
- `Resource::post_error` no longer requires a `&mut DisplayHandle`
#### Additions
- Introduce `Resource::client_id`
## 0.30.0-beta.2
#### Breaking changes
- `delegate_dispatch!` can no longer delegate multiple interfaces at once, in order to properly support
generic delegate base types.
## 0.30.0-beta.1
#### Breaking changes
- Large rework of the API as a consequence of the rework of the backend.
## 0.30.0-alpha10
- Introduce conversion methods between `wayland_backend::Handle` and `DisplayHandle`
## 0.30.0-alpha7
- Introduce `DataInit::custom_init()`
## 0.30.0-alpha5
- Introduce `Display::backend()`
## 0.30.0-alpha4
#### Breaking changes
- The trait `DestructionNotify` is removed, and replaced by a `Dispatch::destroyed()` method.
## 0.30.0-alpha2
#### Breaking changes
- The `DelegateDispatch` mechanism is changed around an explicit trait-base extraction of module
state from the main compositor state.
- The `DisplayHandle` no longer has a type parameter
- Global manipulation methods are moved from `DisplayHandle` to `Display`
## 0.30.0-alpha1
Full rework of the crate, which is now organized around a trait-based `Dispatch` metchanism.
This can effectively be considered a new crate altogether.
