One of the most significant changes in this version is the desktop upgrade to Gnome 46, which introduces a series of improvements and new features among which A global search feature is included that makes it easy to locate files and applications, performance improvements in file manager and terminal emulators, experimental support for the VRR mechanism (variable refresh rate) that optimizes the visual experience, better output quality for fractional scaling, expanded capabilities to connect to external services, an updated configurator and an improved notification system. Additionally, it is worth noting that GTK uses a new rendering engine based on the Vulkan API, which significantly improves the performance and graphical efficiency of the system.

Another important aspect of this update is the improved Windows game support released through Wine, thanks to the increasing sysctl parameter vm.max_map_count from 65530 to 1048576 by default. This change not only allows previously unsupported games to run, such as DayZ, Hogwarts Legacy, Counter Strike 2, Star Citizen, and THE FINALS, but also resolves performance issues with memory-intensive applications, thus providing a smoother experience. user more fluid and without problems.

In addition to improvements in performance and gaming support, this version of Ubuntu includes significant software updates, Well they have been updated important development tools as GCC 14, Python 3.12, OpenJDK 21 LTS, LLVM 18, Rust 1.76, Golang 1.22 and .NET 8, among others. The user applications have also been updated, with new versions of Firefox 124 (with Wayland support), LibreOffice 24.2, Thunderbird 115, Ardor 8.4.0, OBS Studio 30.0.2, Audacity 3.4.2, Transmission 4.0, digiKam 8.2.0, Kdenlive 23.08.5 and Krita 5.2.2, among others.

Additionally, Apparmor configuration changes have been implemented to allow secure access to the configuration files of the GnuTLS and OpenSSL libraries, thus improving system security.

In addition to these updates, Improvements have been made to the installer and system management, and the "ubuntu-desktop-installer" installer has been modernized and is now part of the broader ubuntu-desktop-provision project, offering a more efficient and customizable installation experience, in addition to having also implemented additional security measures such as enabling Apparmor by default to ensure secure access to configuration files.

En APT has changed the priority of the “proposed pocket” repository, which evaluates new versions of packages before they are released to the main repositories for the general public. This update seeks to reduce the probability of automatic installation of unstable updates. Once enabled, updates will no longer be downloaded automatically, but users will be able to selectively install necessary updates.

Regarding network configuration, Netplan 1.0 has been implemented, which uses configuration storage in YAML format and provides backends that simplify access to NetworkManager and systemd-networkd configuration. This new version offers the ability to simultaneously use the WPA2 and WPA3 security standards, adds support for Mellanox network devices, among other improvements.

Finally, it is also worth mentioning that in Ubuntu 24.04 LTS has addressed the year 2038 issue in armhf, ensuring that systems can manage time effectively even beyond that date. Updates have been made to over a thousand packages to implement a 64-bit value instead of the previous 32-bit.
