Quick Summary
Canonical has released the official development roadmap for Ubuntu 26.04 LTS. The schedule outlines the timeline for the upcoming Long Term Support release, which is currently under active development. The roadmap provides specific dates for critical milestones that guide the release process.
The development cycle includes several key phases designed to stabilize the operating system before launch. These phases range from initial feature development to strict freezes that prevent new changes. The schedule is designed to ensure a high-quality release for the Ubuntu community.
Key dates in the roadmap include the Feature Freeze in late March and the Beta release in April. The cycle concludes with the Final Release Candidate in May, leading up to the stable launch. This structured approach allows developers and testers to prepare for the new LTS version.
Release Schedule and Key Milestones 🗓️
The roadmap for Ubuntu 26.04 LTS details a precise timeline for the release cycle. The process begins with the upload of the final development kernel, which is scheduled for February 20, 2025. This marks the transition toward the stabilization phase of the project.
The first major milestone is the Feature Freeze, set for March 27, 2025. At this point, the set of packages included in the release is locked down. No new features or major updates are permitted after this date to ensure system stability.
Following the feature freeze, the Documentation String Freeze occurs on April 3, 2025. This milestone prevents changes to user-visible strings in the documentation. It ensures that translators can finalize their work without interference from last-minute text changes.
The User Interface Freeze is scheduled for April 17, 2025. This date locks down the visual appearance of the desktop environment and applications. No changes to the user interface are allowed after this point to maintain consistency for the final release.
Testing and Beta Release 🧪
The roadmap highlights the importance of public testing before the final launch. The Beta Release is targeted for April 24, 2025. This version provides the community and developers with a nearly complete image of the operating system to identify and report critical bugs.
During the beta phase, the focus shifts heavily toward quality assurance. The Kernel Freeze is set for May 1, 2025, meaning no further updates to the Linux kernel will be included in the release unless they address critical security issues or high-impact bugs.
The testing period continues until the Final Release Candidate on May 15, 2025. If this candidate passes all validation tests without critical issues, it will be promoted to the final stable release. This step is the last gate before the official launch.
Final Release and Support 🚀
The official stable release of Ubuntu 26.04 LTS is scheduled for May 22, 2025. As a Long Term Support release, it will receive extended maintenance and security updates from Canonical, making it a preferred choice for enterprise users and stability-focused individuals.
The release will be available for download on the official Ubuntu servers. It will support standard architectures including amd64 and ARM64. Users upgrading from previous versions will be able to utilize the standard upgrade tools provided by the distribution.
The roadmap confirms the commitment to a predictable release cadence. By adhering to the published schedule, Canonical aims to deliver a reliable and feature-rich operating system. The LTS designation ensures that Ubuntu 26.04 will be supported for five years, receiving regular updates to keep the system secure and current.
