Cos End of Life Dates

Developers rely on Cos to stay informed about the lifecycle of each release, ensuring they can plan and execute timely upgrades to maintain the security and stability of their systems. Created to address the need for transparency around end-of-life dates and supported versions, Cos has become an essential tool for teams that need to manage complex software ecosystems. The maintainers of Cos continuously update the platform to reflect the latest information on Cos releases, providing users with accurate data to make informed decisions. With its comprehensive tracking capabilities, Cos helps developers avoid potential security risks and compatibility issues that can arise when using unsupported software.

The Cos ecosystem consists of 16 versions, with 12 of these already having reached their end-of-life, and 4 remaining active. The latest stable version, cos-125-19216-395-55, is the current benchmark for supported releases. However, developers should be aware that another version, cos-117, is scheduled to expire on 2026-09-01, marking an important milestone in the Cos lifecycle. This information is crucial for planning and executing upgrades, as using unsupported versions can expose systems to unnecessary risks. The most recent end-of-life date was 2026-05-12, when version cos-113 reached the end of its support period, underscoring the dynamic nature of the Cos release landscape.

Given the current security landscape, Cos has a clean slate with 0 tracked CVEs and 0 critical vulnerabilities, indicating a strong security posture. As a result, there is no most affected version to report, and no Known Exploited Vulnerabilities (KEV) have been identified. While this is a positive situation, developers should still remain vigilant and ensure they are using a supported version of Cos to minimize potential risks. By staying informed about the latest Cos releases and their corresponding end-of-life dates, developers can proactively manage their software dependencies and maintain a secure environment for their applications.
