Why upgrade to the latest versions of Java?

Compatibility with spring boot:

• Spring Boot 1.x :?

Java support: Spring Boot 1.x requires at Minimum Java 7 for versions up to 1.3.x?

and Java 8 from version 1.4.x.

End of Life: It is important to note that Spring Boot 1.x has reached its End of Life (EOL), meaning it is no longer receiving security or maintenance updates.

• Spring Boot 2.x :?

Java support: Spring Boot 2.0 to 2.4 supports Java 8, 9, 10, 11.

Java 8 and 11: These versions of Java are most commonly used with Spring Boot 2.x because they provide long-term stability.

• Spring Boot 2.5:?

Java Support: Starting with Spring Boot 2.5, there is an effort to support Java versions beyond 11, including Java 16 and 17, depending on the specific Spring Boot version.

• Spring Boot 3.x:?

Java support: Spring Boot 3.0 requires at Minimum Java 17, aligning with LTS versions of Java and taking advantage of new Java features and performance improvements.

The latest version of Spring Boot is version 3.2.3.

Recommendation :

For a new project, it is recommended to use the most recent version of Spring Boot that is compatible with the LTS version of Java you plan to use. This ensures you benefit from the latest features, performance improvements and security fixes.

?Increase the cost of vendor support for older versions, as you need to pay for security patches.????

• Oracle's recommendations to uninstall versions prior to version 8 to avoid security risks.
• Third-party Java libraries are no longer developed or supported

Older versions are no longer publicly supported.

Community Support :

• Transitioning to Java 22 provides access to a vibrant community of developers, collaboration opportunities, support, and a conducive environment for learning and leveraging new Java features .

Improved Performance :

• Java optimizes the Java Virtual Machines (JVM) speed, enhances garbage collection mechanisms, and strengthens just-in-time (JIT) compilation, resulting in faster and more efficient Java applications .

Enhanced Security :

• Upgraded security features in Java protect user data, ensure application integrity, and reduce the risk of security threats like unauthorized access and malicious attacks .
