The latest Ubuntu version brings together new features, performance improvements, and security enhancements to appeal both to regular desktop users and developers. As of April 2025, the most recent interim release from Canonical is Ubuntu 25.04, codenamed Plucky Puffin. Alongside it, the current Long Term Support (LTS) release remains Ubuntu 24.04 LTS Noble Numbat, which provides a stable foundation for users who prefer extended support. This update cycle highlights Ubuntu’s release rhythm newer, cutting-edge interim versions every six months, and more stable LTS releases every two years. For many users, this dual approach balances innovation with reliability.
Ubuntu Release Cycle
Ubuntu’s release schedule is predictable and helps users decide when to upgrade or stick with a stable version. The short-term or interim versions arrive every six months, while LTS versions are released in April every two years. The LTS versions are important for those who want long term stability since they receive standard security maintenance for five years. With additional support services, such as Ubuntu Pro and Expanded Security Maintenance (ESM), support can be extended further.
Interim vs LTS Releases
Interim releases like Ubuntu 25.04 are full releases with new features, newer kernels, and updated desktop environments. But they are only supported for nine months. On the other hand, LTS releases such as 24.04 Noble Numbat are supported for five years under standard maintenance, and they are ideal for servers, production machines, and users who want less frequent updates.
What’s New in Ubuntu 25.04 Plucky Puffin
Ubuntu 25.04 brings a number of noteworthy improvements, especially for developers and desktop users. Because it’s an interim release, it pushes forward with new desktop tools, refreshed environments, and better support for modern hardware. Here are some of its major additions
- Latest GNOME 48 desktop environment, with usability enhancements and modern UI features.
- Improved installer experience, particularly when setting up dual-boot or detecting encrypted drives, including better handling of Windows BitLocker partitions.
- New default PDF reader called Papers, replacing the previous Evince viewer. Papers offers a more modern design built on GTK4 and Libadwaita.
- Enhanced support for developers via devpacks, bundles that include frameworks such as Spring, updated compiler toolchains, newer versions of Python, Rust,.NET, and others.
- Kernel 6.14, which brings improved hardware support and performance on Intel, AMD, and ARM platforms.
- Better user-experience features, including HDR support out of the box, Wellbeing Panel for screen time tracking, new power/battery health modes, and smoother graphics performance thanks to updates like triple buffering.
- Support for confidential computing, especially AMD SEV-SNP features, for those needing higher security in cloud or data center environments.
Improvements for Hardware and Performance
Ubuntu 25.04 includes optimizations tailored to newer hardware. Users with modern GPUs, Intel or AMD integrated graphics, or ARM64 devices benefit from better driver support, smoother graphics, and faster boot times. Also, there is a purpose-built ISO for ARM64 enthusiasts, which helps those using single board computers or ARM laptops. These improvements help Ubuntu stay competitive on both desktop and cloud platforms.
Ubuntu 24.04 LTS Noble Numbat Status and Point Updates
Ubuntu 24.04 LTS is the long term support version and remains the preferred choice for users who want stability over cutting edge features. Maintenance for 24.04 LTS includes routine updates and point releases, which bundle together security patches, bug fixes, and hardware enablement updates. The LTS version is supported until April 2029 for standard updates. With Ubuntu Pro or ESM, support can be extended further.
Ubuntu 22.04.5 LTS as a Point Release
As part of the maintenance of 24.04 LTS, Ubuntu 22.04.5 LTS has been released (for the older LTS cycle) to provide updated installation media and newer kernels, including the Linux 6.8 kernel, which improves compatibility with newer hardware. Such point releases help reduce the update burden for new installations of LTS versions.
Who Should Upgrade?
Deciding whether to upgrade to Ubuntu 25.04 or stay with Ubuntu 24.04 LTS depends on your priorities.
- If you want the latest desktop features, improved visuals, updated toolchains, and are okay with upgrading more often, then Ubuntu 25.04 might be the right choice.
- If you value stability, long term security, and fewer disruptive updates, sticking with Ubuntu 24.04 LTS is safer.
- Developers looking for newer kernels, newer language versions, or better hardware support may benefit from the interim release.
- Servers, production environments, or mission-critical systems should generally prefer the LTS release.℠
Support, Security, and Lifecycle
Ubuntu’s support model ensures that all versions receive security patches during their supported lifetimes. Interim releases are supported for nine months. LTS releases have five years of standard support. With Ubuntu Pro, users can get extended security maintenance and support for Universe packages, and even legacy support beyond the base support period. This makes Ubuntu viable for both individual users and enterprise deployments.
