postmarketOS, an Alpine-based Linux distro designed to run on smartphones, tablets, and other mobile devices, has published its 25.12 release, concluding a six-month development cycle with updates to the distribution’s base system, package management, user interfaces, and device support.

At the foundation of 25.12 is an upgrade to the recently released Alpine Linux 3.23. This base includes the newly released version 3 of Alpine’s package manager, apk. Apk v3 introduces changes intended to improve reliability, including downloading packages before installation, and comprehensive logging of package operations to /var/log/apk.log.

User interface components received broad updates. GNOME was advanced to version 49; the mobile variant remains on GNOME 48.mobile. KDE Plasma Mobile was updated to 6.5.3, bringing enhancements such as improved Waydroid integration, faster lockscreen loading, and homescreen refinements.
