SpringSource Tool Suite (STS) 3.0.0.M2 是 SpringSource（现为 VMware Tanzu 团队的一部分）于 2012 年初发布的里程碑版本（Milestone 2），属于 STS 3.x 系列的早期预览版。该版本基于 Eclipse 3.7（Indigo），深度集成 Spring Framework 3.1.x、Spring IDE 插件、AspectJ 开发工具（AJDT）、m2e（Maven 集成）、Groovy/Grails 支持，并首次强化了对 Spring Roo 和 Spring Security 的可视化支持。作为 M2 版本，它并非正式生产就绪版，主要用于开发者尝鲜、反馈问题及适配新 Spring 生态特性。

注意：STS 已于 2020 年正式停止维护，官方推荐迁移到 Spring Tools 4（基于 Eclipse 2019-06+ 或 VS Code 的现代化轻量级工具，代号 “Spring Tools for VS Code” 和 “Spring Tools 4 for Eclipse”）。
SpringSource Tool Suites 3.0.0.M2 released
I am pleased to announce the availability of the second milestone build of the upcoming SpringSource Tool Suites 3.0.

This M2 build includes a number of significant changes and reflects the new structure of the tooling going forward. The main goal was to move away from one big monolithic tool towards smaller independent components. Therefore the different components of the SpringSource Tool Suite have been separated from each other and are now usable on an individual basis.

All this allows us to start shipping different flavours of our tooling projects. Beginning with this M2 build we start to ship two different ready-to-use distributions:

The Dashboard comes with each distribution and allows you to add the remaining projects into your installation on demand.

Due to the componentization effort some artifacts have been renamed and this renaming has impacted some of the eclipse metadata stored in your projects. The M2 versions of the distributions include migration tools that well help you update your project metadata automatically to use the new naming scheme.

For more details about new and changed features, please refer to the New and Noteworthy for 3.0.0.M2 document.

If you come across incompatibilities, migration problems, bugs, or any other suggestions, please provide feedback in the forum and file issues via JIRA.

Downloads are available from the STS download page, take a look in the „Other Downloads“ section.

3.0.0.M3 is planned for early July 2012, followed by the 3.0.0 Release in early August 2012.
