Canonical has released Mir 2.26.0 \u2014 a new version of the compositor and library set for building shells and graphical environments based on Wayland.<\/p>\n
Wayland and new protocols<\/strong><\/p>\n
\n
A MVP implementation of the protocol has been added ext-input-triggers (V1)<\/strong>.<\/li>\n
The protocol draft has been implemented ext-input-triggers<\/strong> for handling input triggers in Wayland. This functionality is considered privileged and is not included by default.<\/li>\n
The specification file has been updated ext-input-trigger-action-v1.xml<\/strong>: it has been supplemented with clarifications on token validity and availability.<\/li>\n
Added Partial implementation of ext_image_copy_capture_v1 for cursor sessions<\/strong>.<\/li>\n
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<\/strong>.<\/li>\n<\/ul>\n
Rust and architectural development<\/strong><\/p>\n
\n
Development has started of the Wayland frontend in Rust<\/strong>.<\/li>\n
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.<\/li>\n<\/ul>\n
Input subsystem: evdev-rs<\/strong><\/p>\n
\n
Support for touch events has been implemented.<\/li>\n
The device module code has been cleaned up.<\/li>\n
The processing of pointer device events has been corrected: button states have been moved to storage at the individual device level.<\/li>\n
Event processing logic has been reworked for clarity and maintainability of the code.<\/li>\n<\/ul>\n
Cursor, windows, API, and internal infrastructure<\/strong><\/p>\n
\n
For CursorObservers<\/strong> the ability to track changes in the cursor image has been added.<\/li>\n
Component CursorObserverMultiplexer<\/strong> now sends the initial state to newly registered observers.<\/li>\n
Refactoring has been conducted MinimalWindowManager<\/strong>.<\/li>\n
self-repair the index to set the window alpha channel and retrieve it through WindowInfo<\/strong>.<\/li>\n
requires clauses have been added to libmiral templates , which improves the strictness of constraints at the template code level in C++.<\/strong>The transfer of<\/li>\n
logging APIs and default values to mircore has been completed The call to strerror() has been replaced with<\/strong>.<\/li>\n
thread-safe strerror_r() A bug has been fixed where<\/strong>.<\/li>\n<\/ul>\n
Bug Fixes<\/strong><\/p>\n
\n
BasicXCBConnection::destroy_window called xcb_map_window instead of xcb_destroy_window An issue has been resolved where<\/strong>.<\/li>\n
XCB responses were not always freed A bug has been fixed:<\/strong>.<\/li>\n
fullscreen video playback in Google Chrome might not work if the window was not initially in fullscreen mode.<\/strong> For X11, correct setting has been added<\/li>\n
_NET_CLIENT_LIST_STACKING An unsafe implementation of<\/strong>.<\/li>\n
fatal signal handling has been corrected , which was specifically described in the release as 'wildly unsafe'.<\/strong>A bug has been fixed where the check for<\/li>\n
DRM_CLIENT_CAP_ATOMIC was conducted through an incorrect ioctl call.<\/strong> Cleanup and logic improvement have been carried out.<\/li>\n
The logic has been cleaned up and improved. mgk::find_crtc_with_primary_plane<\/strong>.<\/li>\n
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.<\/li>\n<\/ul>\n
Other<\/strong><\/p>\n
\n
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.<\/li>\n<\/ul>\n
