Plasma Desktop now brings enhancements to task icon sizing, panel opacity, and file dragging between screens. Additionally, Plasma Audio Volume Control streamlines unnecessary symlinks and Plasma Systemmonitor correctly positions loading overlays. Powerdevil enhances the battery protection user interface and governs backlighthelper calls effectively.
  • Python-setuptools 70.0: Notable features in this significant version update involve warning emission for ignored [tools.setuptools] entries in pyproject.toml, refined error messaging for pkg_resources.EntryPoint.require, and better handling of None location distributions. The update also refreshes unpinned vendored dependencies, conforms to PEP 625 by standardizing package name and version in filenames, and ensures encoding consistency for .pth files. Obsolete Python < 3.8 code has been eliminated, and pkg_resources now leverages stdlib importlib.machinery. Bug fixes concentrate on streamlining install command race conditions, enhancing handling of nested namespaces with package_dir, and rectifying various pkg_resources method behaviors. The reproducibility patch has also been refreshed.
  • Xen 4.18.2_06: This version resolves intermittent system hangs when Power Control Mode is set to Minimum Power. Patches additionally improve CPU mask handling and interrupt movement in diverse scenarios. Upstream bug fixes focus on scheduler resource data management improvements and include fixes for GNU Compiler Collection 14 compatibility during the build process.

Prominent Package Upgrades

  • NetworkManager 1.48.2: This update bolsters support for matching OVS system interfaces by MAC address and corrects issues related to port reactivation and VPN secrets handling for 2-factor authentication. Connection timestamps are now saved during shutdown to enable proper autoactivation post-restart. Key changes in version 1.48.0 include the deprecation of autotools building, the addition of support for changing OpenSSL ciphers for 802.1X authentication, and the visibility of unmanaged device reasons in the StateReason property through nmcli. Moreover, it replaces the mac-address-blacklist property with mac-address-denylist, improves WiFi 6 GHz band detection, and optimizes performance to prevent high CPU usage during route updates. Version 1.46 introduced dynamic SSID-based stable IDs, randomized MAC addresses, and various enhancements for managing IPv6, D-Bus, and cloud configurations.
  • ibus-table 1.17.6: This update bids farewell to Python2 support and transitions all scripts to Python3 using pyupgrade. It now supports utilizing keys with Unicode keysyms in keybindings, enriching customization capabilities. Additionally, the frames_per_buffer=chunk_size option is now integrated into self._paudio.open() for refined audio handling. The update also features translation improvements from Weblate, with Czech reaching 36.6 percent, Japanese at 45.3 percent, and Chinese (Simplified) at 92.0 percent.
  • btrfsprogs 6.9: The mkfs utility now halts if the mount status remains undetermined with the --force option and corrects the minimum size calculation for zoned devices. The check command removes the --clear-ino-cache option, transferring its functionality to the rescue command group, and adds detection and rectification for inaccurate file extent item ram_bytes values. The qgroup commands now synchronize the filesystem before searching for stale entries, manage uncleaned subvolumes and squota enabled scenarios, and exhibit the cleaning status of subvolumes.
