New in 2.2.6

Let’s have a look at some of the highlights this new edition introduces.

Java 14 support

This is perhaps the biggest new change for Spring Boot.

So before you jump in and download the new version of Spring Boot, take a moment and familiarize yourself with everything new in Java! Especially if you’re still rocking Java 8. A lot has changed since then!

Quick Spring Boot overview

New to Spring Boot? Let’s quickly get you caught up to speed.

Spring Boot is an open source framework based on Java. Originally developed by Pivotal, it helps users create stand-alone, production-grade Spring-based applications with a minimal amount of configuration.

According to the GitHub README, its main design goals are:

  • Provide a radically faster and widely accessible getting started experience for all Spring development
  • Be opinionated out of the box, but get out of the way quickly as requirements start to diverge from the defaults
  • Provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration)
  • Absolutely no code generation and no requirement for XML configuration

Newcomers should view the quick start guide and learn how to create a basic “Hello World” endpoint. But first, you will need a JDK (Java Development Kit) and some form of an IDE.
