Long-Term Support Version (LTSV)
See: Java Long-Term Support Version (LTSV) - https://www.oracle.com/java/technologies/java-se-support-roadmap.html
TLDR: A long term support version (LTSV) refers to a software release with an extended maintenance and update period, typically designed for users and enterprises prioritizing stability and reliability. In the context of Ubuntu, LTSV releases occur every two years and receive official support, including Linux security patches and Linux security updates, for at least five years. These versions are ideal for production environments, offering a balance between modern features and long-term Linux stability.

LTSV ensures that critical updates and security patches are provided over an extended period without the need for frequent upgrades. For example, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS include consistent Linux kernel updates and compatibility with newer hardware while maintaining backward compatibility. The LTSV model is particularly beneficial for servers, cloud deployments, and systems requiring minimal downtime, as it reduces the risks associated with frequent migrations.

Beyond stability, LTSV releases often align with Canonical's enterprise support offerings, such as Ubuntu Advantage, which provides extended security maintenance (ESM) and 24/7 technical support. Developers and businesses rely on LTSV for creating scalable and secure infrastructures, particularly in cloud computing and containerization. By offering predictable updates and extensive support, LTSV remains a cornerstone of software lifecycle management for critical applications.
