Site Changelog

This page documents substantive content updates, corrections, and additions across Ubuntu Portal. Minor typo fixes and formatting adjustments are generally not listed unless they affect technical accuracy.

February 2026

  • Updated the CLI basics guide to account for apt 2.9 behaviour changes — the new default progress output and modified autoremove prompting needed documentation adjustments.
  • Refreshed the Nvidia Optimus troubleshooting section for 24.04 LTS, including revised instructions for PRIME profile switching under GNOME 46 and notes on the 550 driver series power management improvements.
  • Added clarifying notes to the filesystem recovery section regarding fsck behaviour differences between ext4 and XFS.

January 2026

  • Added a filesystem recovery walkthrough to the mounts guide, covering common corruption scenarios and step-by-step fsck procedures for ext4 volumes.
  • Expanded FAQ content across multiple documentation pages based on recurring reader questions — particularly around apt pinning and /etc/fstab UUID handling after drive replacements.
  • Minor corrections to package names in the tools section following a round of repository changes in the 24.04 archives.

December 2025

  • Refreshed the release timeline to include Ubuntu 24.04.1 LTS point release details — upgrade path notes, known issues with certain Realtek WiFi adapters post-upgrade, and revised kernel version references.
  • Updated GRUB configuration examples in the CLI basics guide after update-grub output format changes in the latest grub2 package revision.

November 2025

  • Updated hardware compatibility notes for the kernel 6.8 series, including revised information on Intel Arc GPU support and Thunderbolt dock behaviour under the new kernel.
  • Added a troubleshooting subsection to the Nvidia Optimus page addressing the nvidia-smi reporting discrepancy that appeared with the 545 driver branch on certain laptop models.
  • Corrected a permissions example in the filesystem guide — the umask value was transposed in the NTFS mount options table.

October 2025

  • Expanded the tools section with terminal emulator comparisons covering Alacritty, Kitty, GNOME Terminal, and Konsole — focusing on GPU acceleration support, configuration portability, and resource usage on Ubuntu.
  • Added Wayland-specific notes to several guides where X11-only instructions needed updating for the default Ubuntu 24.04 session.

September 2025

  • Refreshed apt examples across the documentation section to consistently use the modern apt command instead of apt-get where appropriate, with notes on the remaining cases where apt-get is still preferred in scripting contexts.
  • Updated the releases page with end-of-life date confirmations for Ubuntu 23.04 (Lunar Lobster).

August 2025

  • Added mount option recommendations for NVMe drives to the filesystems guide, including noatime performance considerations and TRIM/discard configuration.
  • Revised the about page to better reflect current site scope and section organization.

July 2025

  • Corrected kernel module loading instructions in the Nvidia Optimus guide — the blacklist syntax for nouveau needed an update after the modprobe configuration directory structure changed.
  • Added a quick-reference table of common systemctl commands to the CLI basics page.
