Context & Background

Ubuntu’s Long-Term Support (LTS) releases are a cornerstone of its strategy, providing a stable foundation for users who prioritize reliability and extended support cycles over the bleeding-edge features found in interim releases. LTS versions are typically supported for five years for standard security maintenance and can be extended with Ubuntu Pro for up to ten years. This long support window makes them particularly attractive for enterprise environments, servers, and users who prefer not to undertake frequent system upgrades.

The preceding LTS release, Ubuntu 22.04 LTS (Jammy Jellyfish), has been a popular choice for many. Ubuntu 24.04 LTS, codenamed “Noble Numbat,” represents the next step in this lineage, building upon the advancements of its predecessor and incorporating refinements based on user feedback and ongoing development. The “.3” designation in 24.04.3 indicates that this is a point release, a crucial update that often bundles together a significant collection of bug fixes, security patches, and sometimes minor feature backports that have been tested and stabilized since the initial 24.04 release.

Point releases are vital for LTS users as they allow for the accumulation of important fixes without requiring a full distribution upgrade. This means that users who installed Ubuntu 24.04 LTS shortly after its initial release will now have a more polished and secure experience by simply applying the updates delivered through this point release. It’s a testament to the ongoing commitment of the Ubuntu development team to maintaining the quality and security of their LTS offerings.
