Spring Framework Release History & EOL Status

Spring Framework Lifecycle & End of Life (EOL) Policy

Spring Framework follows a structured support policy that balances innovation with long-term stability. Each major version line receives open-source support for several years, during which the team provides regular maintenance releases that include bug fixes and security patches. The final minor version of each major line is designated for extended commercial long-term support (LTS), offering significantly longer protection for enterprise users.

Open-source support focuses on critical issues and security vulnerabilities for the active branches. Once the open-source support window closes, the version moves into a commercial-only phase where only paying customers with LTS subscriptions continue to receive updates. This approach gives development teams a clear timeline to plan upgrades while ensuring production applications can remain secure for extended periods when needed.

The policy applies to the core Spring Framework and helps organizations align their upgrade cycles with both community-driven improvements and enterprise-grade stability.

Risks of Using End-of-Life (EOL) Versions

Continuing to run an End-of-Life version of Spring Framework exposes your applications to growing risks over time. Without any further security patches, newly identified vulnerabilities in the framework or its dependencies remain unaddressed, increasing the potential for exploits.

You also lose access to official bug fixes, which can lead to persistent stability or performance issues that the Spring team will no longer resolve. Many supporting libraries and Spring portfolio projects gradually drop testing and compatibility for EOL versions, creating hidden integration problems when updating other components.

Organizations subject to compliance requirements often face audit challenges because security standards typically mandate that core frameworks stay under active support. The longer you delay migration, the higher the maintenance effort and operational risk become.

What Happens After Spring Framework Reaches EOL

After a Spring Framework version reaches full End of Life, all official maintenance ceases. The development team stops releasing any patches, security updates, or maintenance builds for that version line. Both open-source and commercial support channels close for issues specific to the EOL release.

Your existing applications will continue to function as before, but you take full responsibility for any future security concerns or defects. Community discussions may still occur, yet no guaranteed assistance or compatibility testing is provided by the Spring team.

Most mature teams treat the EOL date as a non-negotiable milestone and complete their migration to a supported version well in advance. This keeps the application ecosystem secure, maintainable, and aligned with modern Spring development practices.

Tracking & Monitoring Spring Framework EOL Dates

Strong tracking practices begin with maintaining a complete inventory of Spring Framework versions across all your applications and microservices. Many teams integrate this information into their central configuration management or monitoring platforms for easy visibility.

Conduct periodic reviews, at least every quarter, to identify versions approaching the end of their open-source support window. Setting automated reminders when less than nine to twelve months of support remain helps ensure upgrade planning starts early enough to avoid pressure.

Include EOL awareness in your architecture review process. By treating support timelines as important project milestones, teams can schedule migrations smoothly and maintain a consistently secure and supportable codebase.

How To Check Your Spring Framework Version

Checking the exact Spring Framework version in your project is quick and should become a regular habit. For Maven-based projects, run this command in the project root directory.

mvn dependency:tree | grep spring-core

For Gradle projects, use the following command.

./gradlew dependencies | grep spring-core

You can also inspect the version programmatically inside your application by accessing the Spring version property or checking the JAR manifest.

import org.springframework.core.SpringVersion;
System.out.println("Spring Framework version: " + SpringVersion.getVersion());

Run these checks across development, staging, and production environments to keep your version inventory accurate and spot any outdated instances before they become a risk.
