This is an update to the original blog post about creating docker images with Spring Boot 2.3. There were a few things related to image creation that changed between the first milestone of Spring Boot 2.3 and the GA release.

The two new features introduced in Spring Boot 2.3 to help improve image creation techniques were: layered jars and buildpack support.

Layered Jars

The layered jar feature evolved quite a bit as we started adding support for custom layers. While the need to express layers that the jar should be split into for image creation was evident, changing the format of the jar to do so no longer seemed necessary. Spring Boot 2.3 includes support for layering a jar using a layers.idx file. The layers index file provides a list of layers and the parts of the jar that should be…

Spring Boot 2.4.0.M2 has just been released, and it brings with it some interesting changes to the way that application.properties and application.yml files are loaded.

If your applications use the fairly typical setup of only using a single application.properties or application.yml file, then you’ll probably not notice any difference. If, however, you have applications that use more complex setups (such as profile specific properties), you might want to read on to learn about what we’ve changed and why.

Why We’re Making These Changes

With recent versions of Spring Boot we’ve been working hard…

On behalf of the team and everyone that contributed, I am pleased to announce that the second milestone of Spring Boot 2.4 has been released and is available from our milestone repository. This release closes just over 250 issues and pull requests.

If you're trying this release with an existing Spring Boot 2.3 project, please note the slight change in the format of the version. 2.4.0-M2 is using our new versioning scheme.

Highlights of this second milestone include:
