+This release includes support for Apache Groovy 3, Micronaut framework 3, Gradle 7, Spring Boot 2.6, Spring framework 5.3, and Spock 2.0.
 
 Apache Groovy 3 is a major highlight of this release. It comes with a brand new Parrot parser and a bunch of new features and capabilities. The Parrot parser supports additional syntax and language features, such as lambda expressions, default methods with interfaces, and a lot more. In addition, several new extension methods are added to existing Java classes. See the https://groovy-lang.org/releasenotes/groovy-3.0.html#releasenotes[release notes for Groovy 3.0] for details.
 
 Grails framework 5 updates to Spring 5.3.10 and Spring Boot 2.5.5. We strongly recommend checking the following Spring technologies release notes for more information.

 Grails framework 5 is built with Groovy 3.0.7, which requires JDK 8 as the minimum version of JRE. We have tested most Grails projects up to JDK 14.
