April 2025 was a dynamic month in the world of Linux, marked by a significant new release from a major player, ongoing updates across popular distributions, and important security fixes. As we close out the month, let’s recap some of the key happenings in the Linux ecosystem.
Ubuntu Steps Forward with 25.04 “Plucky Puffin”
Headlining the April news was the release of Ubuntu 25.04, codenamed “Plucky Puffin.” As an interim release (not a Long Term Support version), “Plucky Puffin” serves as aटेस्टbed for new technologies and features that will eventually make their way into future LTS releases. This version comes packed with updates, including:
GNOME 48: Bringing the latest desktop environment with user experience improvements, potentially including battery health features, a wellbeing panel, and enhanced HDR support.
Linux Kernel 6.14: Incorporating the newest kernel with improved hardware support, performance tweaks, and new features for developers like sched_ext. Gamers might also benefit from the new NTSYNC driver for better Windows game compatibility via Wine/Proton and support for technologies like Nvidia Dynamic Boost.
Updated Toolchains: Developers will find the latest versions of programming languages and tools like Python, Golang, Rust, .NET, OpenJDK, and GCC.
Installer and Boot Improvements: Work continues on refining the installation process and exploring alternatives to initramfs-tools like Dracut for a better boot experience.
New Default Applications: “Papers” replaces Evince as the default PDF reader, offering a more modern interface.
Geolocation Updates: Ubuntu 25.04 transitions to BeaconDB for geolocation services.
Keep in mind that as a non-LTS release, Ubuntu 25.04 will receive support for 9 months. For users prioritizing long-term stability, Ubuntu 24.04 LTS remains the recommended choice.
Fedora’s Continuous Evolution and Development Focus
Fedora, known for its commitment to free and open-source software and its role as an upstream for Red Hat Enterprise Linux, saw its usual stream of package updates throughout April. Notably, there were critical OpenJDK updates released for supported versions like Fedora 40 and 41, addressing security vulnerabilities.
Beyond routine updates, April saw the launch of a significant Fedora Dependency Upgrade Project. This initiative aims to modernize the core Fedora codebase by updating outdated libraries, improving robustness and maintainability, and facilitating community contributions to testing and development. This behind-the-scenes work is crucial for the future health and stability of the distribution.
Debian’s Stable Foundation Receives Security Attention
Debian, the bedrock for many other Linux distributions, continued its focus on stability and security in April. While not a major version release month, Debian users received important security updates to address vulnerabilities. This included a Linux kernel security update (DSA 5907-1) and a critical security advisory for tomcat9 (DLA-4108-1) addressing a remote code execution vulnerability in Debian 11 (bullseye). These regular security patches are a cornerstone of Debian’s reliability.
Arch Linux: The Rolling Edge
For users of Arch Linux and its derivatives, April was another month of continuous updates. As a rolling-release distribution, the latest software versions are constantly pushed to the repositories. A notable change observed in April was the replacement of the Redis package with the Valkey fork, following licensing changes by the upstream Redis project. This demonstrates the Arch community’s agility in adapting to shifts in the open-source landscape.
Additionally, the Arch-based distribution CachyOS released its April 2025 ISO update, bringing specific improvements particularly for handheld gaming devices like the ASUS ROG Ally and Lenovo Legion Go, alongside general package updates. Development continued on various fronts, including updates to the Haskell toolchain with GHC 9.4.8 entering testing and ongoing efforts in a “Spring cleanup” to manage packages in the repositories.
Linux Mint’s Glimpse into the Future
While Linux Mint didn’t have a major stable release in April, the development team provided insights into upcoming features and ongoing work. News from the Linux Mint blog highlighted progress on:
- Nemo File Manager Enhancements: Improvements to the file search functionality within the Nemo file manager.
- Cinnamon on Wayland: Continued development to improve compatibility and support for the Wayland display protocol in the Cinnamon desktop environment, including better handling of keyboard layouts and input methods.
- OEM Support in LMDE 7: The upcoming LMDE 7 (Linux Mint Debian Edition) is planned to include full support for OEM installations, making it easier for vendors to pre-install Mint on computers.
- Cinnamon JavaScript Engine (CJS) Versioning: Changes are being made to version the CJS independently of Cinnamon, allowing for more frequent updates to the JavaScript engine.
April also marked the end of support for Linux Mint 20. Users still on this version were strongly advised to upgrade to a supported release like Linux Mint 21.3 to continue receiving security updates and support.
A Month of Progress
In summary, April 2025 for Linux users was characterized by a significant new interim Ubuntu release showcasing future directions, crucial security patching across distributions like Debian and Fedora, and continuous development and adaptation within rolling-release distributions like Arch. The focus on both immediate security needs and future improvements highlights the vibrant and ever-evolving nature of the Linux ecosystem.
