Kotlin End of Life Dates

Developers seeking a modern, high-level programming language for cross-platform development often turn to solutions that offer seamless integration with existing ecosystems. Created to address the needs of modern application development, Kotlin has established itself as a viable option, given its ability to interoperate fully with Java and run on the Java virtual machine. Maintained by JetBrains, Kotlin's popularity stems from its concise syntax, safety features, and tooling support, making it an attractive choice for building a wide range of applications, from Android apps to backend services.

The landscape of Kotlin versions reflects its ongoing evolution, with a total of 12 versions released to date. Out of these, 11 versions have reached their end-of-life, with the most recent EOL occurring on 2026-06-03 for version 2.3. This leaves only one active version, which is the latest stable version 2.4.0. Since there is no announced date for the next version to reach its end-of-life, developers can continue to build and maintain their applications with confidence, knowing that the current version will receive support and updates. This active maintenance is crucial for ensuring the long-term viability and security of applications built with Kotlin.

Given its design and maintenance, Kotlin presents a favorable security profile, with no known Common Vulnerabilities and Exposures (CVEs) tracked to date. This means that there are no critical CVEs to address, and consequently, no most affected version has been identified. The absence of CVEs underscores the language's robustness and the effectiveness of its development and review process. With this clean security slate, developers can focus on leveraging Kotlin's features and capabilities to build secure, high-quality applications without the burden of addressing known vulnerabilities, ensuring a solid foundation for their projects.
