<\/center> <\/p>\nIn the new release: <\/p>\n
- \n
- The package base has been synchronized with Alpine Linux 3.15.\n
- The number of officially supported community devices has increased from 15 to 23. Support has been added for the Arrow DragonBoard 410c, Lenovo A6000\/A6010, ODROID HC, PINE64 PineBook Pro, PINE64 RockPro64, Samsung Galaxy Tab A 8.0\/9.7, and Xiaomi Pocophone F1. The Nokia N900 PC communicator has been temporarily removed from the list of supported devices, with support being moved from the community-supported category to the 'testing' category, for which ready builds are not published. This change is due to the departure of the maintainer and the necessity of updating the kernel for the Nokia N900 and testing builds. Among projects that continue to develop builds for the Nokia N900, Maemo Leste is noted.\n
- Builds with user interfaces Phosh, KDE Plasma Mobile, and Sxmo, optimized for mobile devices, have been created for supported smartphones and tablets. For other types of devices, such as the PineBook Pro laptop, builds featuring desktop environments based on KDE Plasma, GNOME, Sway, and Phosh have been prepared.\n
- Mobile user interface versions have been updated. The Sxmo (Simple X Mobile) graphical shell, adhering to Unix philosophy, has been updated to version 1.6. A key change in the new version is the switch to using the Sway window manager instead of dwm (support for dwm remains as an option) and the transition of the graphical stack from X11 to Wayland. Other improvements in Sxmo include a redesign of the screen lock code, group chat support, and the ability to send\/receive MMS.

<\/center> <\/p>\n- The Phosh environment, based on GNOME technologies and developed by Purism for the Librem 5 smartphone, continues to be based on version 0.14.0, proposed in the release of postmarketOS 21.06 SP4. It implements features such as a splash screen for indicating application launches, a Wi-Fi indicator in hotspot mode, rewind buttons in the media player widget, and playback cessation when headphones are disconnected. Among additional changes added in postmarketOS 21.12, many GNOME programs, including gnome-settings, have been updated to GNOME 41, as well as resolving issues with the display of the Firefox icon in the preview window.

<\/center>\n- A TTYescape handler has been added, allowing users to switch to console mode with a classic command line on devices that do not have an external keyboard connected. This mode is considered analogous to the 'Ctrl+Alt+F1' screen provided in classical Linux distributions, which can be used for selective process termination, diagnosing interface hangs, and other diagnostics. Activation of console mode is performed by pressing the power button three times while holding down the volume up button. The same combination is used to return to the graphical interface.

<\/center>\n- The postmarketos-tweaks application has been updated to version 0.9.0, introducing the ability to manage the application list filter in Phosh and change the deep sleep timeout. In postmarketOS 21.12, this timeout has been reduced by default from 15 to 2 minutes to save battery life.

<\/center>\n- The toolkit for generating boot files (postmarketos-mkinitfs) has been rewritten, improving support for scripts to install additional files related to the boot process (boot-deploy), which has significantly increased the stability of kernel and initramfs updates.\n
- A new set of configuration files for Firefox (mobile-config-firefox 3.0.0) has been proposed, adapted for the design changes in Firefox 91. In the new version, the Firefox navigation bar has been moved to the bottom of the screen, the reader view interface has been improved, and the ad blocker uBlock Origin has been added by default.
