Grails Changelog

What's new in Grails 4.0.1

Nov 8, 2019

Grails 4 ships with the following dependency upgrades:
Groovy 2.5.6
GORM 7 and Hibernate 5.4 (now the default version of Hibernate for new applications)
Spring Framework 5.1.5
Spring Boot 2.1.3
Gradle 5.1.1
Spock 1.2
Micronaut Parent Context:
Micronaut is now the parent application context of Grails thus allowing using many Micronaut features including the Micronaut HTTP Client and Kafka Client.
Micronaut has also been used to improve startup and reduce overall memory consumption of Grails applications (along with associated improvements in Spring Boot 2.1).

New in Grails 3.0.4 (Jul 29, 2015)

New in Grails 3.0.0 (Mar 31, 2015)

Core Features:
Groovy 2.4:
Grails 3.0 comes with Groovy 2.4 which includes many new features and enhancements.
Spring 4.1 and Spring Boot 1.2:
Grails 3.0 comes with Spring 4.1 which includes many new features and enhancements.
In addition, Grails 3.0 is built on Spring Boot 1.2 which provides the ability to produce runnable JAR files that can embed Tomcat, Jetty or Undertow containers.
Gradle Build System:
Grails 3.0 deprecates the older Gant-based build system in favour of a new Gradle-based build that integrates closely with the Gradle plugin ecosystem.
Application Profiles:
Grails 3.0 supports the notion of application profiles via a new profile repository. A profile encapsulates an application structure, set of commands, plugins and capabilities. For example the "web" profile allows construction of web applications deployable to a Servlet container. In the future more profiles will be developed targeting different environments.
Redesigned API based on Traits:
The Grails API has been redesigned so that public API is correctly populated under the grails. package whilst private / internal API that is subject to change can be found in the org.grails. package. The core API has also been rewritten and based around the Groovy Traits.
Web Features:
New Interceptors API:
In previous versions of Grails, filters were used to define logic that intercepts controller action execution.
As of Grails 3.0, this API is deprecated and has been replaced by the new Interceptor API. An example interceptor can be seen below:
class MyInterceptor {
boolean before() { true }
boolean after() { true }
void afterView() {
// no-op
Development Environment Features:
New Shell and Code Generation API:
Replacing Gant, Grails 3.0 features a new interactive command line shell that integrates closely with Gradle and provides APIs for writing scripts that interact with Gradle and perform code generation.
The new shell integrates closely with the concept of application profiles with each profile capable defining profile specific commands. As with previous versions of Grails, plugins can define new shell commands that can invoke Gradle or perform code generation and project automation tasks.
Enhanced IDE Integration:
Since Grails 3.0 is built on Gradle, you can now import a Grails project using IntelliJ community edition or GGTS's Gradle tooling support without the need for Grails specific tooling. Grails 3.0 plugins are published as simple JAR files greatly reducing the need for additional IDE support specific to Grails.
Application Main Class:
Each new Grails 3.0 project features an Application class that has a traditional static void main signature, meaning to run or debug a Grails 3.0 application from an IDE like IntelliJ or GGTS you can simply right-click on the Application class and execute to start your Grails application. All Grails 3.0 tests can also just be run from the IDE directly without needing to resort to the command line (even integration / functional tests!).
Testing Features:
Integration and Geb Functional Tests:
Grails 3.0 supports built in support for Spock/Geb functional tests using the create-functional-test command. Functional tests are based on Spring Boot's test running mechanism and load the application just once for an entire suite of tests. The tests can be run from and IDE and don't require the command line.
Gradle Test Running:
Since Grails 3.0 is built on Gradle the test execution configuration is much more flexible and can easily configured to execute in parallel.
