Welcome to the official release of Weston 1.12. Weston's internal code has been restructured into a new software library, libweston. This is intended for use by other compositor efforts that want to more easily utilize Weston's internal functionalities. Weston's own compositor is now a user of this library.
As well, another new library named libweston-desktop provides an additional level of functionality of relevance to compositors implementing a desktop metaphor style of graphical interface. This library API is designed around xdg_shell functionality, providing for handling of popups, window state, and interfacing with Xwayland. Both libweston and libweston-desktop should be treated as unstable libraries (i.e. their APIs are subject to change). A versioning scheme has been adopted for their ABI provisioning to enable compile-time detection of breaks. In other words, this enables users to detect incompatibilities at install-time in their packaging system, rather than when they try to actually use the software. The system is designed to help not only with released Weston components but also to flag inconsistencies when using development snapshots of the libraries, to help developers avoid problems due to inconsistencies, too. Support for the new version 6 of the xdg_shell protocol has been implemented in the Weston compositor, and all clients are ported to it. See the wayland-protocols 1.7 release notes for details on the included changes. A pointer locking and confinement API is implemented for Weston using the wp_pointer_constraints protocol, to allow clients to define window regions to confine the pointer to. These regions can be irregular; a client is included to demonstrate confinement to a H-shaped region, for example. A relative pointer protocol (using wl_relative_pointer) has also been introduced, which allows clients to continue receiving pointer movement deltas even when the pointer's absolute position is clipped for example to the edge of the monitor. The Raspberry Pi backend (rpi-backend) and renderer have been dropped. This code was reliant on a proprietary driver stack, and proved not to be maintainable within Weston. Several other features, build improvements, bug-fixes, code refactorings, refinements to destruction processes, and so on are included. See below for the full list of changes.
