Spring Framework整体版本更新时机及术语含义咨询

Great question—this is a super common point of confusion when you're first diving into Spring's ecosystem, so let's break it down step by step.

First: The Two Meanings of "Spring Framework" #

You're spot-on here—this term gets used in two distinct ways:

• The Core, Standalone Project: This refers to the specific project that implements core features like dependency injection, AOP, and application context management. It has its own dedicated version line (e.g., 5.x, 6.x) and is the foundational layer that almost all other Spring projects rely on.
• The Ecosystem Umbrella: Colloquially, developers often use "Spring Framework" to refer to the entire family of Spring projects (Spring Boot, Spring Security, Spring Data, etc.). Officially, though, Spring calls this the Spring Portfolio or Spring Ecosystem to avoid confusion with the core project.

How "Spring" (and the Core Framework) Gets Updated #

Let's clarify the versioning flow, since it's tied to how the projects are structured:

• Core Spring Framework Versioning: The core project's version is managed centrally by the Spring team, following semantic versioning (MAJOR.MINOR.PATCH):
  • MAJOR versions (e.g., 5 → 6) happen when there are breaking changes—like requiring a newer Java version, removing deprecated APIs, or major architectural overhauls. These are planned well in advance as part of the team's public roadmap.
  • MINOR versions (e.g., 5.2 → 5.3) add new features while maintaining backward compatibility.
  • PATCH versions (e.g., 5.3.20 → 5.3.21) focus on bug fixes, security patches, and small tweaks.
    The sub-modules within the core project (like spring-core, spring-context) don't have independent versions—their updates are rolled into the core framework's overall version.
• Independent Spring Projects: Tools like Spring Boot, Spring Security, or Spring Data are separate projects with their own release cycles and versions. However, they always depend on a specific compatible version of the core Spring Framework. For example, Spring Boot 3.x requires Spring Framework 6.x, while Spring Boot 2.x relies on Spring Framework 5.x. These projects update on their own schedules, but they align their major versions with the core framework to ensure compatibility.
• When Does "Spring" Get a "New Version"?: When you hear about a "new Spring version" (like Spring Framework 6.0), that's specifically referencing the core project's major release. The rest of the ecosystem then adapts to this new core version over time—you'll see projects like Spring Boot release their own major versions that support the new core framework. Developers usually track the core framework version or the Spring Boot version (since Boot is the most common entry point) to gauge the ecosystem's overall "current" version.

To circle back to your initial thought: You're partially right that module updates drive minor/patch versions of the core framework, but major core versions are planned strategically. The independent projects update on their own, but they're tied to the core framework's compatibility, so the ecosystem moves in sync around core major releases.
