Spring Boot End of Life Dates: Complete Version EOL Guide (2.x, 3.x and 4.x)

By Scott Bissett  ·  Last updated: August 9, 2026  ·  Covers Spring Boot 2.7 through 4.1

Spring Boot follows a time-limited support model where each minor version has a defined open source (OSS) support window and an optional commercial support extension. If you're running an unsupported Spring Boot version, you're missing security patches and bug fixes — and likely out of compliance with many enterprise security policies. This guide covers every Spring Boot 2.x and 3.x version with exact OSS and commercial support end dates, what changes between versions, and how to plan your upgrade.

Key Dates at a Glance

• Spring Boot 4.1: OSS support ends 2027-07-31; commercial support ends 2028-07-31
• Spring Boot 4.0: OSS support ends 2026-12-31; commercial support ends 2027-12-31
• Spring Boot 3.5: OSS support ends 2026-06-30; commercial support ends 2032-06-30
• Spring Boot 3.4: OSS support ends 2025-12-31; commercial support ends 2026-12-31
• Spring Boot 3.3: OSS support ends 2025-06-30; commercial support ends 2026-06-30
• Spring Boot 3.2: OSS support ends 2024-12-31; commercial support ends 2025-12-31

Spring Boot Version EOL Dates — Complete Table

Understanding the Spring Boot Release Cycle

Spring Boot releases a new minor version approximately every 6 months, alternating between May and November each year. The support lifecycle is:

OSS Support Window (~12–15 months)

From release until approximately 3 months after the next minor version ships. During this window, the Spring team publishes patch releases (e.g., 3.4.1, 3.4.2) with bug fixes and security patches. This is the standard, freely available support that all Spring Boot users rely on.

Commercial Support Window (VMware Tanzu / Broadcom)

An extended 6-month to 1-year window beyond OSS EOL, available to Tanzu Spring Runtime subscribers. The Spring team backports critical security fixes into the commercial release stream. This is intended for enterprises with longer upgrade cycles, not as a permanent state.

End of Life

After both windows close, the version is fully end of life. No patches of any kind are available through any channel.

Spring Boot 4.1 and 4.0 — Current Supported Releases

Spring Boot 4.1, released June 30, 2026, is the current recommended version, with OSS support until July 31, 2027. Spring Boot 4.0, released November 30, 2025, remains supported until December 31, 2026. Both are built on Spring Framework 7.0 and require Java 17 as a minimum. The 4.x line brings major modernization to the Spring ecosystem and is the target for new projects in 2026.

Spring Boot 3.5 — OSS EOL June 30, 2026

Spring Boot 3.5, released May 31, 2025, reached OSS end of life on June 30, 2026. Built on Spring Framework 6.2. Key improvements: enhanced virtual threads support (Project Loom), improved observability with Micrometer, Spring gRPC integration, and further AOT/GraalVM native image improvements. Commercial support (Tanzu) extends to June 30, 2032, but open source users should upgrade to Spring Boot 4.0 or 4.1.

Spring Boot 3.4 — OSS EOL December 31, 2025

Spring Boot 3.4 OSS support ended December 31, 2025. It is still eligible for commercial support for Tanzu Spring Runtime subscribers until December 31, 2026. It introduced improvements to structured logging, enhanced Docker Compose support, and improved @MockitoBean test annotations. Upgrade to Spring Boot 4.0 or 4.1.

Spring Boot 3.3 — OSS EOL June 30, 2025

Spring Boot 3.3 OSS support ended June 30, 2025, and commercial support ended June 30, 2026. Spring Boot 3.3 is no longer receiving patches through any channel. Upgrade to Spring Boot 4.0 or 4.1.

Spring Boot 3.2 — OSS EOL December 31, 2024

Spring Boot 3.2 OSS support ended December 31, 2024. This was a significant release that introduced initial virtual threads support for Tomcat and Jetty, RestClient (replacing RestTemplate for new code), and initial GraalVM native image improvements. The OSS window is now closed, and commercial support ended December 31, 2025. Upgrade to 4.0 or 4.1.

Spring Boot 2.7 — OSS EOL, Long Commercial Support

Spring Boot 2.7 was the last Spring Boot 2.x release and the final version to support Java 8. OSS support ended June 30, 2023. However, commercial support (VMware/Broadcom Tanzu) extends to June 30, 2029 — making 2.7 the longest-supported Spring Boot 2.x version. Even with commercial support active, the underlying Spring Framework 5.3 reached OSS EOL August 31, 2024, meaning unpatched framework-level vulnerabilities may exist. Migration to Spring Boot 3.x or 4.x is strongly recommended.

Spring Boot vs. Spring Framework EOL

Spring Boot and Spring Framework have separate but related release cycles. Spring Boot sits on top of Spring Framework:

Spring Framework 5.3 reached end of life August 31, 2024. This means even if you're using Spring Boot 2.7 with a commercial subscription, the underlying Spring Framework is no longer patched.

Migrating from Spring Boot 2.7 to 3.x

The biggest migration challenge is the Java EE to Jakarta EE namespace change. Every import that begins with javax. must be changed to jakarta. — this affects web, persistence, security, and many other APIs. Key steps:

1. Upgrade to Java 17 first — Spring Boot 3.x requires it as a minimum.
2. Run OpenRewrite's UpgradeSpringBoot_3_0 recipe to automate namespace migration and most dependency updates.
3. Replace deprecated javax.* imports throughout your codebase.
4. Update Spring Security configuration — the 6.x security model uses a lambda DSL; the older WebSecurityConfigurerAdapter is removed.
5. Update property keys — many Spring Boot properties were renamed in 3.x.
6. Test thoroughly: Spring Boot 3.x also removed several deprecated APIs that 2.7 still supported.
