🥇Mir 2.26.0 | ProHoster

Canonical has released Mir 2.26.0 — a new version of the compositor and library set for building shells and graphical environments based on Wayland.

Wayland and new protocols

A MVP implementation of the protocol has been added ext-input-triggers (V1).
The protocol draft has been implemented ext-input-triggers for handling input triggers in Wayland. This functionality is considered privileged and is not included by default.
The specification file has been updated ext-input-trigger-action-v1.xml: it has been supplemented with clarifications on token validity and availability.
Added Partial implementation of ext_image_copy_capture_v1 for cursor sessions.
If the user refreshes the page in private browsing mode, Firefox will interpret this as a problem and suggest cursor image transmission via ext_image_copy_capture_v1.

Rust and architectural development

Development has started of the Wayland frontend in Rust.
Work on the input platform based on Rust has continued. This is not yet the main input processing path, but a practical step toward gradually integrating Rust into the project.

Input subsystem: evdev-rs

Support for touch events has been implemented.
The device module code has been cleaned up.
The processing of pointer device events has been corrected: button states have been moved to storage at the individual device level.
Event processing logic has been reworked for clarity and maintainability of the code.

Cursor, windows, API, and internal infrastructure

For CursorObservers the ability to track changes in the cursor image has been added.
Component CursorObserverMultiplexer now sends the initial state to newly registered observers.
Refactoring has been conducted MinimalWindowManager.
self-repair the index to set the window alpha channel and retrieve it through WindowInfo.
requires clauses have been added to libmiral templates , which improves the strictness of constraints at the template code level in C++.The transfer of
logging APIs and default values to mircore has been completed The call to strerror() has been replaced with.
thread-safe strerror_r() A bug has been fixed where.

Bug Fixes

BasicXCBConnection::destroy_window called xcb_map_window instead of xcb_destroy_window An issue has been resolved where.
XCB responses were not always freed A bug has been fixed:.
fullscreen video playback in Google Chrome might not work if the window was not initially in fullscreen mode. For X11, correct setting has been added
_NET_CLIENT_LIST_STACKING An unsafe implementation of.
fatal signal handling has been corrected , which was specifically described in the release as 'wildly unsafe'.A bug has been fixed where the check for
DRM_CLIENT_CAP_ATOMIC was conducted through an incorrect ioctl call. Cleanup and logic improvement have been carried out.
The logic has been cleaned up and improved. mgk::find_crtc_with_primary_plane.
Fixed the occlusion behavior: if a surface has an opaque area but its alpha is not equal to 1.0, it should no longer be used as fully occluding.

Other

Noted the increase in the number of new participants in the project: the release of Mir 2.26.0 includes contributions from several newcomers, which developers interpret as a sign of community growth around Mir.
